The Microtronix Avalon Multi-port Front End provides a complete, easy-to-use solution for interfacing multiple Avalon Memory Masters to a single Avalon Memory Mapped Slave such as Intel® FPGA's line of memory controller IP cores.The Avalon MPFE integrates easily into any Intel® Quartus® Prime II Platform Designer (formerly Qsys) project. It is designed to optimize the performance of Avalon bus based video and streaming data systems. It supports one Avalon Memory Mapped Master port and up to 26 Avalon Memory Mapped Slave ports. The MPFE supports independent clocks for each slave and implements buffers in on-chip memory for each port to support high speed data transfer to the master port.


  • Five priority levels for arbitration of port service requests
  • Up to 26 Avalon Memory Mapped Slave interfaces
  • User configurable cache for each Slave port
  • Each slave port can use an independent clock
  • Two Avalon Slave port types: Burst Slave and Random Slave

Device Utilization and Performance

Arbitration Controller: 4,000 LEs, Avalon Burst Port: 240 LEs (per port), Avalon Burst Port: 1200 LEs (per port).Typical Avalon-MM bus interconnect clock rate: 175 MHz
