Multi-Port Front-End The Northwest Logic Multi-Port Front-End Core from Rambus provides a multi-port interface to Northwest Logic 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
