AMBA AHB ram
u need to write a wrapper for ur ram to make ur module compatible with the ahb signals.
it may be a master or slave port depending on ur application.
if ur ram has to write out data to any peripheral then u have to write a master interface. if ur ram doesn't have to write out any data and only accepts data that is some peripheral writes to your module a slave port is sufficient.
refer the amba ahb manual for implementation.
