# KF8237 - 8237/8237A-like programmable DMA controller written in SystemVerilog 

## About

KF8237 is programmable DMA controller like 8237/8237A.

## Differences from original

- AEN timing

- Memory-to-Memory transfer is not supported (TODO)

- I/O ports is separated into input and output port

## Features

- Single transfer mode

- Block transfer mode

- Demand transfer mode

- Cascade mode

- 3 Transfer types (Read/Write/Verify)

- Autoinitialize

- Rotating priority

- Compressed timing

## Block
