Rijurekha Sen

Hi,

According to several posts, a detailed documentation of the hardware accelerator on the c5505 ezdsp was supposed to be released. Is there any update on that?

Thanks,

Hi Rijurekha,

The hardware accelerator document is in the process of being released and should be available by early next week. We will post an update once it has been released.

Best regards, Vishal

Thanks Vishal. What is the advantage/disadvantage of calling the hardware fft functions from RAM (using hwafft.asm) vs calling them from ROM (uncommenting the addresses in c5505.cmd)?

Thanks,

Riju

Hi Riju,

Calling the FFT functions from ROM allows you to use the on-chip RAM to store other code/data. Since each of the eight FFT functions is quite large, placing them in ROM frees approximately 4 KBytes of on-chip RAM.

Calling the FFT functions from RAM allows you to step through each assembly instruction, set breakpoints, and debug the FFT functions.

The instructions, results, and execution times are identical.

Hope this helps,
Mark
