At the January 98 PWG 1394 meeting, I mentioned that Technology
Rendezvous Inc. was prototyping the IP1394 solution, and had
already developed SBP-2 target and initiator modules. (FYI, I've
appended the announcement that I was forwarded to the bottom of
this message.)
I approached them about sharing some rough estimates of code size
for the IP1394 glue, SBP-2 target and initiator, and 1394 bus
manager modules to get a feel for how "heavy" the protocol
implementations really are. They graciously shared the flowing
estimates with us, and certainly deserve our thanks. Since the
technology is still being developed, these implementations are
certainly going to be tuned and the numbers will change a little
bit.
Component Rough ROM size (KBytes)
--------- -----------------------
SBP-2 initiator core 15 +/- 5
SBP-2 target core 15 +/- 5 (incl. Mgmt+Fetch agent, no exec agent)
IP1394 glue layer 15 +/- 5 (curr proto impl., not quite fully func)
OS supplied TCP/IP stack 50 -> 100 (depends on other stack components incl.)
Serial Bus Mgr 12 -> 15
Tailgate core 12 +/- 3
Link Ctlr driver cores 12 -> 18

>/*** About TRI ***/
>Technology Rendezvous Inc. is a leading supplier of embedded
>system solutions. TRI provides a well layered and portable
>IEEE-1394 software for peripheral and embedded systems. The
>software stack supports both Isochronous & Asynchronous data
>transfers and various protocols including SBP-2 target, SBP-2
>initiator, SBP-2 with MSP, SBP-2 with printer profile and
>IP over 1394. The software stack has been designed to work with
>or without an operating system and hence it is very suitable for
>deeply embedded systems. The stack supports TI and IBM link
>Controllers and the Hardware adaptation layer (HAL) of the stack
>can be changed to support other 1394 Link Controllers.
>TRI also provides IEEE-1394 link layer core and FPGA based test
>and development environment as a complete system solution.
