From: oen_no_spam on 23 Jun 2005 10:47 Hi Jim, My problem is the SHARC, not the TigerSHARC. The TS permits debug using it's external bus. Anyway it looks like you have nice tools. Thanks, Luiz Carlos
From: oen_no_spam on 23 Jun 2005 10:53 Hi Ron, We sell boards based on ADSP-218x. But it is running out of gas! We are looking for a floating point DSP replacement. Well, even BlackFin doesn't have a host port! I'll try again to get more information from ADI. Thanks, Luiz Carlos.
From: Jaime Andr?s Aranguren Cardona on 23 Jun 2005 11:15 To Luiz: I think that if you were heading for the TS, but are also considering the ADSP-2136x, it's because you need some big computational power for your application. Couldn't a ADSP-21161 work for you? It has a host port, allowing you to debug it without the need of diving deep into the JTAG internals. I think that Ron's suggestion of the emulator + remote access software (NetMeeting, VNC) could be a good option for you. Ask Dr. Mike Rosing, maybe he could give you good advice, since his company (BeastRider, http://www.beastrider.com/) makes low cost JTAG debuggers for SHARC, 2106x and 2116x, though. Anyway, they are experienced with what you need. To Ron Huizen, Jim Thomas: Thanks for coming in, and commenting from your experience.

In both cases, we treat the JTAG port as a black box so we don't know any more than you about the specifics. We also provide the capablility to upload code into flash on our boards using USB or RS-232 using a proprietary loader that we wrote. This doesn't provide debug support but it does work well for production programming and upgrades. We have customers using our dspblok 21261sm with its FPGA for a host port interface. Depending on you application, SPI, SPORTs, USB or RS-232 are also possibilities with our dspstak boards. -- Al Clark Danville Signal Processing, Inc. -------------------------------------------------------------------- Purveyors of Fine DSP Hardware and other Cool Stuff Available at http://www.danvillesignal.com

Hi Jaime, Yes, a lot of processing power, besides you never have enough! The ADSP-21161N runs at 100MHz, has 1Mbit of on chip SRAM and costs $26. As we need the processing power of one or more Tigers, a cluster of ADSP-21161s would be very expensive. The ADSP-21363 runs at 333MHz, has 3 Mbits of internal RAM and costs $17. But lacks the host port. I hate TI's assembly language! What will I do? :) As I said, we sell boards, so it's not practical to bundle an external debugger. Luiz Carlos |
