SHARC development -- VisualDSP++ is pretty much the only game in town, right?

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...

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...

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
