TMS570LS3137: Help on TMS570LS3137 loading

Part Number: TMS570LS3137
Other Parts Discussed in Thread: OMAPL138,

Hello,

We want dedicated to use TMS570LS3137 as IOP for handle 2 CAN, 2 Flexray, 1 Ethernet, 1 UART, 1 SPI EEPROM, EMIF (1 FPGA for another I/O purpose, 1 SRAM ( at least 8MB),1 to OMAPL138) ,

Who knows the loading might be too heavy or not

Thanks,

Andy

    Hello Andy,

    The loading is really dependent on the transfer rates (not just baud rates but frequency of data arrival) and processing needs on the incoming data. If it is simply receiving data and moving it to another protocol and sending it out, then there could be heavy use of the DMA to help manage moving of data independent of the CPU but if there is a need to process the data for each communication channel before sending it on its way via another channel, then it is highly dependent on the nature of the processing and how often data has to be processed and moved around.

    In short, we can't really answer this without specifics about the application. If I had to venture a guess, I would think that it shouldn't be a problem but again, it is pure speculation without application details about frequency of data reception and transmission as well as turn around requirements on each protocol.
