The Microtronix Streaming Multi-port SDRAM Memory Controller IP Core provides a native RD or WR local port bus interface to SDRAM memory. The core integrates: a burst memory controller core, a port arbitrator and intelligent look-ahead FIFO controller into one easy-to-use core. It supports SDR, DDR, DDR2 and Mobile DDR memory devices in a single IP Core assuring designers of a smooth low-risk migration path with changing SDRAM technology. The core supports up to ten independently clocked streaming data sources operating from one shared high-bandwidth memory system. Using the intuitive Microtronix GUI interface, with a few clicks of a mouse, designers can create a multi-port system, a design task which would normally take several man-months of effort!


  • Supports 10 local bus RD/WR interface ports
  • Provides simple target and register interfaces
  • Reduces the memory design process to a two-step compilation process
  • FIFO port interface enables independent clock domains for memory and local buses
  • Source-synchronous date capture design
