8237 DMA Controller IP Core from iWave Systems

BANGALORE, India - Oct. 10, 2013 - PRLog -- 8237 DMA Controller is a peripheral core for microprocessor systems. It controls data transfer between the main memory and the external systems with limited CPU intervention.

Highlights

·         Compatible with 8237 and uPD71071

·         Controller can improve the system performance by allowing external devices to transfer data directly to or from system memory

·         Multi-mode programmability allows the user to select from three different transfer modes

Benefits

·         Used to reduce the load of the CPU

·         Configurable for ease of use

Features

·         24-bit length address register

·         16-bit length count register

·         4 independent DMA channels

·         4 clock / 1 bus cycle

·         Byte transfer / word transfer selectable

·         Supports three transfer modes (Single, Demand, Block)

·         DMA request Mask able on an individual channel basis

·         Software DMA request in uPD1037 mode

·         Auto initialization function

·         Two kinds of channel priority order (Fixed & Rotating)

·         Cascading capability

Target Applications

·         Core is designed to use with industry standard microprocessors.

Deliverables

·         Design Document

·         Verilog RTL or Netlist Source code

·         Test Bench

·         IP User Guide
