# CDMA
## Overview
CDMA library provides CDMA (Crystal Direct Memory Access) functionality for
user-space applications, enabling asynchronous memory read and write operations
between hosts or between host and devices.

The key features are described as follows:

1. Peer-to-peer communication between hosts, enabling bidirectional asynchronous memory read or write.
2. Asynchronous memory read and write between host and devices via DMA.
3. Asynchronous memory read and write between devices and host via DMA.
