Abstract
A unique memory access system and method to handle memory access requests to a memory shared by multiple independent data access devices (“IDADs”). More particularly, the present invention relates to a method and system that allows IDADs to efficiently execute memory access requests without having to wait for the shared memory to be available. In addition, the IDADs do not have to be designed to observe the specific memory protocol. The memory access requests from the IDADs are accepted by access request logic which then queues the requests. Memory access logic then executes the requests from the queue when the shared memory is available. The memory access logic places data obtained from read requests in a read buffer for the IDADs to access when convenient.
