Here is the latest compilation of information on the
MIB RTOS & networking software. No info on Java, yet,
and almost no info on tool sets, but there is enough
information in the document to do a RAM budget for
an RTOS, network stack, FTP Server, Telnet Server,
and HTTP server.

comments: 1. The preemption threshold model implemented in ThreadX may be useful.
2. The same individual, Bill Lamie, was the author of both
Nucleus Plus & ThreadX. ThreadX was written after Nucleus PLUS.
These two RTOSes are so similar that the third party network vendor
named Interniche uses the same build for both. ThreadX claims to
be smaller & faster. Those claims are probably true.
3. I put the following question to the Express Logic (ThreadX) sales
rep - "Will the kernel (& tool sets) merge the 512KB and 1 MB
chunks of memory on the TC11IB into a "unified" memory space ?"
The reply was - "If the TC11IB has the ability to remap memory areas
then it's certainly possible to put them together. If not, it is
very simple for ThreadX to manage memory in non-contiguous areas."
4. Nucleus PLUS does support MMUs for some platforms (PPC, ARM). For
the TriCore, expect a flat, unprotected memory space. It is possible
that MMU support could be developed, but it would be an additional
expense.
5. With regard to a "unified" memory space - Nucleus PLUS supports
multiple memory pools. However, if the various memory segments are
not contiguously addressed, Nucleus PLUS will not "unify" the segments.

comments: 1. IGMP is required to support multicasting. Multicasting is not
identical to broadcasting.
2. The Interniche products include "NicheTool", a menu driven
debugging/optimizing tool.
3. The Interniche products are zero copy stacks. Their claim for
speed is that for most target systems, TCP/IP transfer rates are
limited by processor speed. Is this claim an oxymoron ?
4. Adding IGMP to NicheStack to support multicasting will increase its
footprint by ~ 2 KB code & 850 bytes for data.

comments: 1. NicheStack supports an unlimited number of devices. NicheLite
supports only one hardware device. IGMP and multicasting are not
included in NicheLite. I do not know if they can be added as options.
2. Descriptions of the socket APIs for NicheStack & NicheLite are
available in my office.
3. Very cheesey name.
4. Elmic's TCP/IP stack uses an integration file to port to various
operating systems. A pre-configured integration file for ThreadX
is available from Elmic. The sales rep could not tell me if an
integration file is available for Nucleus PLUS. She is
researching that question. She was sure that some of their
customers are using the Turbo Treck TCP/IP stack with Nucleus
PLUS (& with VxWorks). A tech note on porting has to be sent.
5. For its TCP/IP stack Elmic Systems claims zero copy to/from the
application, inside the protocol stack, and to/from the device
driver. The TCP/IP stack requires a timer to signal the protocol.
6. The IGMP package costs $5K. The TFTP package costs $3K. A package
containing the DHCP client, relay agent, & BOOTP is available for
$5K. The RAM requirements for these packages have been requested.
7. The vendor supplied figures did not include code size for ICMP,
ARP, or RIPv2.
8. The number 16 KB was arrived at by adding together the vendor
supplied figures for interfaces, memory, SACK, Path MTU, Speed
Opt, & IP frag. (See material which follows)

ETHERNET DRIVERS
We will need one. Since the TC11IB is a new chip it is unlikely that an
Ethernet driver will exist. I am very wary of attempting to develop this
driver in-house. It strikes me as a time sink. It is likely that we will
make development of the Ethernet driver a part of the RTOS port to the TC11IB,
or if we use a third part network stack, we may want to farm this job out
to the developer of the stack. We will be charged for it, but I have no idea
of price at this time.
The salesman at ATI estimated that an Ethernet driver would require approximately
4 - 5KB for code and 0.5KB of additional RAM space.
The salespeople at Elmic Systems use a figure of ~ 3KB code for Ethernet.

comments: 1. FTP servers require a filesystem. For the ATI Nucleus line
of products, a file abstraction layer is provided with Nucleus
NET that allows the FTP _client_ to use a block of memory as the
physical file medium. The Nucleus FTP Server seems to require a
true file system. The Nucleus FILE system does provide a RAM
disk driver. I am seeking confirmation that the Nucleus FTP
Server can work with this RAM disk driver.
2. The Interniche FTP Server requires a file system. NicheFile is
available. NicheFile can use RAM, flash, or disk. It's basic
footprint is 2 KB, and the price is $2,000.

comments: 1. The FTP package requires a file system. I find no mention of a
a file system package on the Elmic web pages. I will investigate
further. ThreadX does offer a file package (FileX) which can use
both RAM & Flash. FileX costs $5250.00. The footprint of FileX
varies from one architecture to the next. The footprint for the
code varies from 5KB to 20KB, plus 500 bytes for global data
structures, plus 200 bytes for each media opened, plus a buffer
sized to hold 1 sector of data. Presumably the Turbo Treck FTP
Server could use this file system. The Nucleus PLUS file system
also has a RAM driver.

comments: 1. Nucleus WebServ includes a utility which can be used to select
files on a hard disk & convert them to a C file which contains
the binary representation of the files and an associated directory.
This converted reprsentation then serves as an embedded file
system. Optionally, Nucleus FILE can be used.
2. Serves static HTML files, can build dynamic pages, can respond to
function execution requests, HTTP 1.0/1.1 Support, CGI (as a plugin),
Server Side Include (SSI), multiple concurrrent requests, Basic &
DES authentication.
3. WebPort appears to take the same approach to a file system as
Nucleus WebPort, but the needed utility is _may_ be an optional,
added cost item.
4. HTTP 1.1 support, SSI, CGI, a "server side" push capability that
allows for continuous update of browser screens, Basic & DES
autnentication
5. HTTP 1.1, CGI, dynamic HTML pages, HTML 2.0, 3.2, 4.0, stndrd &

memory, task level debugging, remote invocation of Nucleus PLUS
services. The shell appears to have very limited capabilities.
PROTOTYPING TOOLS/ENVIRONMENTS
ATI provides 2 products which can be used to begin software development prior
to the availability of the target hardware. The first product is known as
Nucleus MNT. Nucleus MNT is, basically, a version of Nucleus PLUS that has been
adapted to run in a Windows environment. It used the Windows thread model to
manage tasks and the Microsoft Visual C++ tool set for code development.
The second product is Nucleus NET for MNT. Nucleus NET for MNT is a binary
bundle of the Nucleus networking products that have been ported to Nucleus MNT.
It is used to simulate (via a shared memory region) a environment which consists
of tasks running under multiple versions of Nucleus MNT within a Windows
environment. I am unclear on the full capabilities of Nucleus Net for MNT,
but it appears to also enable communication with nodes on a physical network
via the Windows NT/2000 routing facilites. Nucleus MNT is $995 per seat.
Nucleus NET for MNT is also $995 per seat.
ExpressLogic provides a WIN32 port of ThreadX which would enable the development
of code under Windows that is written to the ThreadX API. I have very little
information on this particular product. The price for this product is $12,500
for three seats.
TOOL SUITES
There appear to be two candidates for tool sets - the Green Hills Multi IDE and
the TASKING tool suite by Altium. Green Hills is integrated with ThreadX.
TASKING is integrated with Nucleus PLUS, and can also be used with ThreadX.
Green Hills appears to be particularly strong in the area of language support,
offering not only assembler, C, C++, and Embedded C++ (EC++), but several
variants of C++ & EC++ that enable/disable certain features of the language.
TASKING appears to be (very) strong in the area of support for the specifics of
the TriCore architecture and specific chips which use that acchitecture,
including specific support for TriCore V1.3, the PCP2 processor and the TC11IB
chip.

Pricing
I do not yet have detailed info on pricing. However, we can expect the
tool sets to cost ~ %5.5K to $6.5K per seat for a node-locked license.
JAVA
I have not yet had the opporutnity to explore Java platforms/JVMs.
Sample configurations
I'm going to start with the networking software becuase it is, in many respects,
the most complex. In his email of 3/8/2002, (subject: eVLA discussion March
12),Barry listed the follwoing items as a starter list for the networking
software:
Socket connection
UDP (directed & broadcast)
NFS
FTP (client & server)
rlogin or telnet (client & server)
and discussion of thiese points led to the addition of
ICMP
HTTP
IPv6
My attempt to translate these requirements into the terms of this document
results in the following:
NETWORK STACK, including
TCP
UDP
IPv4
ICMP
ARP
TFTP client
sockets layer
sockets API
ethernet driver
Ipv6 is not yet available from the vendors queried for this report. Most or all
expect to have it available in Q2 or Q3 of 2002. Most or all plan a dual
stack implementation that will support both IPv4 & IPv6. The IPv6 stacks will
probably be fairly expensive (~ $10 - $15K), and will consume more RAM than the
IPv4 versions.
NETWORK "PACKAGES", including
TFTP Server
FTP Server
Filesystem for FTP Server
FTP Client
Telnet Server
Telnet Client
HTTP Server
No one at any time, on any web site, or in any conversation mentioned NFS. I
admit to having forgotten about NFS in the course of my research. I can/will
ask about it, but I doubt that it is available.
RAM BUDGET
NETWORK STACK
All of the network stacks except NicheLite include at least a few protocols not
mentioned above - typically, BOOTP, DNS client, DHCP client, and in some cases
RIP and RARP. Since most or all of the stacks are implemented as libraries
which do not include unused/unreferenced components, I will attempt to make
adjustments based on vendor-supplied info where possible. The estimated amount
of additional RAM is based on one connection. I do not really have enough
expertise or information to estimate the amount meeded for additional
connections.

Codes size for Nucleus NET was computed by taking the max of the avg size (75KB)
and subtracting the figures given by ATI for BOOTP, DHCP client, DNS client, and
RARP. IGMP and RIP II are also included in the Nucleus NET stack. For IGMP, I
averaged the figures given by Elmic (3.8KB) and Interniche (2.8KB) and
subtracted the result. RIP II was ignored as I have no information.
Code size for Turbo Treck was based on adding the sizes given for TCP, UDP,
IPv4, socket layer, socket API, TFTP client, and add a few KB to account for
ICMP and ARP. RAM requirements were taken simply as the sum of the
vendor-supplied figures.
The Interniche stacks include NicheTool, a debugging & optimizing tool.

comments: 1. The Interniche WebPort HTTP server has a feature of potential
interest to us - a server-side push facility that allows for
the continuous update of browser screens.
File system for FTP Server
To help simplify my life, I will examine only the filesystems associated with
the two RTOSes - Nucleus FILE and FileX.
Nucleus FILE - from 30KB to 45KB for the code + ~ 7KB for data. For the
purposes of the RAM budget, I will use the figure 47KB. Nucleus FILE does come
with a RAM disk driver & can use those flash devices on the market which emulate
an ATA/IDE disk. To use raw flash for the file system a media manager layer is
required. ATI does not offer the media manager, but they are aware of several
third part sources.
FileX - 5KB to 20KB depending on processor architecture, plus 500 bytes for
global data structures, plus 200 bytes for each media opened, plus a buffer
sized to hold 1 sector of data. Take 20KB as the code size, 1 media opened,
and 512 bytes as a sector size: total ~ 21.2 KB.
