Dual-port on-chip memory for two nios communication

hello,

I implemented 2 nios processors. i want to send some calculations from one nios to other nios. so i decided to use Dual-port on-chip ram for this.

For example i want to send a simple 2 sinus calculations from one to other. How can i implement this communication with c code?

Hi, Taha

 

You can implement the dual-port RAM to be one write port and one read port. One Nios write the sinus data to the write port, and the other Nios read it from the read port.

The write and read ports can be implemented by using a single clock, or separate clocks.

 

Please refer to below for implementation:

You may use pointer to the variable in the dual port RAM.

 

Thanks.
