hi, this might be specifically to BIill. I have a BFin BF537-EZKIT board (96kHz codec, 64MB SDRAM, 4M flash). ucLinux runs neatly, but the audio is not supported at all on this card. Bare metal dsp works fine, been playing getting analog from ADC, filtrating with variable fir-filter and then outputting to DAC. Once I coded double buffered audio and used 1D-convolution in time domain, convoluting left and right channels, and there's enough power to do that in real time.
The U-Boot bootloader has serial i/o so Scheme REPL should be easy. Haven't looked much the s7-code, but the bin-elf-gcc compiler may have all the ingredients. Audio (perhaps) is sufficiently easy to implement. First I was thinking of Forth (coded that ages ago for 8085), but Scheme could be more usable. It's really a pity the bf537-version of ucLinux needs extra ADC/DAC-card to get audio on EZKIT. tia -matti _______________________________________________ Cmdist mailing list [email protected] http://ccrma-mail.stanford.edu/mailman/listinfo/cmdist
