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 and FIR. I did not see an equivalent on SHARC, despite having a large ROM (4Mb on 371). Can we build ...

Just curious... to perform SHARC software development (particularly on their newer SHARC devices), you pretty much have to pony up the $$$ for VisualDSP++, yes? I found a few old projects for porting, e.g., gcc to the SHARC architecture (such as he g21k project... which hasn't been updated in well over a year), but nothing that appeared current/maintained. This surprised me a little, s...


SHARC dtmf decode source

Does anyone have an example of dtmf decoding using a SHARC dsp? How about a Goretzel routine written for the SHARC? Thanks for your help.

SHARC, cache and sdram

Hi, I really liked the VDSP and VisualAudio but I have a serious double about SHARC. In my application, the program will most likely reside on SDRAM. But SHARC has an inst cache that holds only 32 instructions. Does it mean if I have a loop has more than 32 instructions, the program sequencer will have to make multiple access to the SDRAM in a loop? If this is true, SHARC is out of my l...

Hello, Anyone has experience using gnICE with SHARC processors? I'd like to know if it's possible to download a dxe file through the gnICE JTAG interface into any SHARC processor. I wouldn't care to lose emulation capabilities or integration with VisualDSP++. I know that emulation is currently restricted to propietary tools. Thanks in advance, Marcos

I spent a bunch of time tracking down an issue with the 21161 SHARC, so I thought I'd mention it to you guys. The issue has to do with the timing of the automatic context switching on returning from interrupts, specifically with SIMD mode and a delayed RTI instruction. On the SHARC, when certain interrupts are received, the MODE1 and ASTAT registers are automatically pushed onto the stack,...

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.

Hi Sharc fellows, I'm stuck with a problem which is trivial for those who've done it. However, I don't find documentation which helps me. Given, I want to multiply two stored variables with two constants from a table (all are floating point 40bit) , then sum the results and store the new result for further use.

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 external device can drive the transfer. However, I see on the oscilloscope that the SHARC starts t...

Hi Folks, I've been getting acquainted with the SHARC 21369 the last few days and have some questions on its memory architecture: 1. Is the basic idea a sort of crossbar switch in which the three buses, DM, PM, and IOP, are connected with the four parallel memory spaces ("blocks" in ADI's parlance) in as parallel a manner as possible? E.g., if a data value, program value, and I/O...
