Hope it's ok to post this question here, otherwise let me know.
I'm considering buying a Korg MR-1000 portable audio recorder which uses a Blackfin BF532 400 MHz core processor as the main controlling unit. The I/O bus speed appears to be 133 MHz. The maximum sampling frequency normally is 5.6 Mhz per channel (2 channels - one bit) but varies between many settings, also 24 bit, 192 kHz. However, I'm interested in rewriting the code so that the sample frequency can go up to e.g. 5.6 MHz * 4 (one bit).
As far as I can see the ancillaries like RAM, harddisk etc. operate at much higher frequencies (maybe the 133 MHz bus speed?) or seem to be able to manage this.
My question is if it is likely to be accessible to rewrite the code for higher sampling & data storage rates, while maintaining the other parts of the code? If so I am interested in connecting with a person who is capable of doing so to discuss what it takes (budget frame is below $1000).
