Streaming Multi-port SDRAM Memory Controller

Overview

The 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!
