Other Parts Discussed in Thread: TMDSDOCK28335
I am a user of the TI eval board for the TMS320F28335, also known as TMDSDOCK28335
This uses a 100 pin DIMM.
I want to gang several of these DSP boards together where one DSP copies a set of floating point numbers into memory of a second identical eval board,,,,,and so on.
I believe SPI can be used to do this with interrupts.
Has anyone ever done this? Are there tutorials or app notes on how to do this?
I also think DMA or external zone based memory accesses can also be used but I do not know enough about it, I am also not sure if the 100 pin DIMM eval board has the pins necessary to do it,
Does anybody know if this has been done and if so are there any reference designs or tutorials?
Basically all I want to do is distribute processing to a number of parallel DSPs to improve execution time, and do some inventive programming and architecting.
What I am looking for is suggestions and hints and ideally a detailed example. But if there are none I would also be very happy just knowing it is possible and then I will spend time figuring out the details.
Thanks.
