I am currently designing a dual processor system. One of the processors is a NIOS and the other is external to the FPGA and is a Freescale Coldfire. I have a requirement for both of the proces...

Hi Paul,

You could use dual port RAM if you are planning on simultaneous read/write from coldfire and Nios II. The single port RAM will allow for sequential operation only, i.e., only one master can have access to this RAM at a time. So you can select the RAM configuration (dual port/single port) as per your design requirements.

Cheers!

I have the same needs with external processor :

I want to instantiate a Dual-Port in SOPC

- Data will be written by NIOS or DMA.

- Data will be read by external processor.

Have you some idea ?
