Hi, I plan to use both EMIF1(32-bit) and EMIF2(16-bit) which are connected with FPGA.

Our system can access like below. Could you let me know if below usages is possible ?

1) CPU1 software access EMIF1 and EMIF2 to read/write FPGA.

2) CPU2 software access EMIF1 to read/write FPGA.

Best regards,

Hi,

1) CPU1 software access EMIF1 and EMIF2 to read/write FPGA.

Yes, it can be done.

2) CPU2 software access EMIF1 to read/write FPGA.

Yes, it can be done but please note that at any given time only one master (CPU1 or CPU2) has write access to EMIF1 based on EMIF1 semaphore ownership.

Regards,

Vivek Singh
