Multi-Port Front-End

The Rambus Multi-Port Front-End Core from Rambus provides a multi-port interface to Rambus Memory Controller Cores.

Overview

The Rambus Multi-Port Front-End Core from Rambus provides a multi-port interface to Rambus Memory Controller Cores.

Each user request is provided with its own request priority.
The arbiter selects requests based on priority and then round
robin arbitration. The arbiter can also perform Quality Of Service
(QOS) based arbitration. In this mode, the arbitration
results in each port receiving a specified amount of memory
bandwidth. 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.

The Multi-Port Front-End Core includes the Multi-Burst Core. 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
Multi-Port Front-End Core can be used with or without the Multi-Burst Core.

The Multi-Port Front-End Core can optionally include the
Memory Test Core which performs address and data testing.

The Multi-Port Front-End Core can be used with the ReorderCore
to perform request reordering. The Reorder core rearranges
the order of the requests coming from the Multi-Port
Front-End to prioritize high priority requests and optimize
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. Data coherency is maintained during
the reordering operation.

Rambus also provides IP Core customization services.

Why Anti-tamper Sensors Matter: Agile Analog and Rambus Deliver Comprehensive Security Solution

If your device processes valuable data, controls a critical function, or connects to a wider network, it’s a target. Attackers don’t just try to break software; they increasingly physically tamper with hardware; probing, fault injecting, or opening enclosures to bypass protections and extract secrets. The consequences range from IP theft and fraud to orchestrated downtime across fleets of connected devices.
