I am in trouble with connecting DSPs to MCU,
Actually I planed to connect three DSPs to MCU over SPI first, but found that DSPs support only master mode and don't support multiple master mode.
The MCU supports also I2C, but maximum bit rate does not meet system requirement.
1> Can tms320c6671 be operated as a peripheral?
I didn't find any CS pin in 6671, so I don't think I can use MCU's external bus i/f.
Am I right? Or, if I am wrong, please let me any clue.
2> 6674 instead of three 6671s
The system should process three high speed signals at once.
If I use 6674 instead of three 6671s, is it possible that three cores can access different area of internal shared memory or external DDR3 memory at the same time?
