How can I access same RAM module in many different modules ?

[sweetlies12]

Hi experts,

Could you help me out this problem, please ?
In my project, I have to access same RAM to read/ write content in different modules. I cannot instantiate many RAM because it creates independent RAM module.

Thank you very much.

Hi Sweetlies,

I need some info from your questions,
1.whether you need to read different address at a time in a single ram?
2.Are you using any ip or your own rtl?

Hi Sureshaa,
1. Just one address at a time is OK.
2. I wrote my own rtl. Each module ( consequently ) has to read , process and write back to RAM.

Any suggestion would be appreciated.

Ok then you are reading a address and feeding the data to 'n' no of blocks. The 'n' no of blocks will process and needs to write 'n' no of data into the same ram.correct me if i am wrong. And please be specify where the problem is?
