Multi-Port Front End Memory Module IP Core

Overview:

The Multi-Port Front-End provides a multi-port interface to Memory Controller Cores. It also performs request reordering to maximize memory throughput and prioritize high priority requests.

Each request is provided with its own request priority. High priority requests are selected by the arbiter and moved to the
front of the reorder queue for priority processing. Each port also has a programmable time out period. Once a request times out, its priority is raised to the highest level ensuring its quick execution.

Request reordering is performed to maximize memory throughput. This includes moving same bank/same row requests next to each other, same bank/ different row requests away from each other, moving reads next to reads and write next to writes, and other throughput optimizations.

The Multi-Port Front-End also incorporates the functionality of the Multi-Burst Module. It automatically translates long burst requests into multiple requests matching the memory’s native burst length. This enables read or write requests of 256 data cycles or more.

The Status Port notifies the user when each request is dispatched to the Memory Controller Core. It also provides Reorder Queue status.

The Multi-Port Front-End is provide with a reference design which incorporates example user logic for each port.
