Introduction
This DRAM Controller core provides two basic benefits:
- A simple and convenient tool to achieve high system performance.
- Cost and PCB area reduction, by using the combination of DRAM and Multiport
core instead of multiple external memories (e.g. FIFO etc.)
- The PROCMultiPort™ DRAM Controller provides a flexible interface to DRAM. It
allows the definition of multiple ports, each with it's own characteristic
parameters.
Key Features:
- Each port has it's own clock
- Each port (and memory) can work with a different data width
- Simple interface (similar to synchronous FIFO) for Sequential ports
- Straightforward random memory access with Random ports.
- Possibility of progressing in Segmented Mode.
- Minimum external delay; DRAM controlled directly from DFF's.
- DRAM zero wait state
- Automatic arbitration between ports, with priority given to random
access ports
- Allows burst DRAM access with unlimited burst length.
- Automatic generation of refresh cycles at background.
