TMS570LS3137: I would like to do EMIF asynchronous communication using the TMS570LS3137.

Part Number: TMS570LS3137

Dear All.

I would like to do EMIF asynchronous communication using the TMS570LS3137.

I will create a task to verify asynchronous EMIF communication.
And when an external device writes data to the EMIF asynchronous area, I want this task to recognize it and read the memory area.

What I'm curious about is is there a way for the task to recognize when an external device writes data to the emif area? For example, something like interrupt.

It's a basic question, but I'm really curious as I'm using TI chips for the first time.

Best Regards,

  • Hi Iblee,

    Using asynchronous communication, you can interface NOR or SRAM memories.

    That means you can write data to the memories or else you can access the written data from the memory. But remember these memories can not write any data they will just store the data written by the master.

    Like as shown in above block diagram, the master peripherals like CPU/DMA will access the slave memories like NOR flash or SRAM through EMIF asynchronous communication.

    What I'm curious about is is there a way for the task to recognize when an external device writes data to the emif area?

    So, this is not possible, external devices will not write any data to the EMIF area. EMIF area is not a physical memory, it is virtual address region and using that region we can access external memories.

  • Dear Jagadish.

    It's getting worse and worse.
    I'll study some more and ask again.
    thank you.
