Analog Device SHARC DSP

I have a few question about AD SHARC DSPs. 1. I read ADSP-21375 datasheet but I still don't know whether I can use DATA port as General Purpose IO? This question concerns also ADSP-21367/8/9. 2. I heard that all new SHARC DSP (early revision) have some mistake. Is that true? I want to use...

Multi-Sharc architecture

Help with SHARC 21161 SPORTs

I am having problems with SHARC 21161 transmit serial port starting too early with external frame sync. On my board, an external device supplies a frame sync signal to the DSP. The DSP is supposed to wait until it receives the frame sync before starting the serial transfer. In this way, the e...

MP3/Ogg-Vorbis and SHARC

do they make $10 SHArCs anymore?

there used to be an ADSP-21161 that was about $10 at Digi-Key. now the cheapest SHArC i can see at Digi-Key is the ADSP-21262 which is about $20. i thought the older ADSP-21065L was under $10 eventually. didn't they replace that with a newer chip that's just as cheap? i know about the ADI Si...

DSP Processor Tools

Code generation for ADSP-211xx SHARC processore

questions about SHARC

Hi, I am evaluating ADI SHARC 21375/371 against TI C6722/6. I am kinda lean toward Sharc because it's easier to deal with. Before making decision there are a couple of things I'd like to find out. 1. ROM use. TI has a nice DSPlib inside the ROM that has many functions we need such as FFT an...

Re: Question on fixed point division

Here's my 2 cents. To do a divide, first code it up in C, and check the lst file to see what the compiler generated. The compiler may inject the code directly, or it may call a function. I think Code Composer includes the source code for all the functions. Another approach that is efficie...

SHARC ADSP FFT from SDRAM

Hi I'm having some issues with a SHARC ADSP 21369. I'm perfroming a number of FFTs on 8k sample blocks using the ADSP21369 EZKIT LITE and have encountered a show stopper. If I run the FFT using the SDRAM to store the buffers (too big for internal) then it takes 10 times as long. 2-3 times I w...

Will ADI ever make DSCs?

Hi: TI recently announced the TMS320F283xx 32-bit DSC with an FPU. This is basically an upgrade over the C28xx platform which had an integer-only 32-bit 150MHz DSP core and loads of peripherals oriented toward motion control. The gobs of counter/timers on the C28xx got me interested a f...
