Section 21 Ethernet Controller Direct Memory Access

Controller (E-DMAC)

This LSI includes a direct memory access controller (E-DMAC) directly connected to the Ethernet
controller (EtherC). A large proportion of buffer management is controlled by the E-DMAC itself
using descriptors. This lightens the load on the CPU and enables efficient data transfer control to
be achieved.

21.1 Features

The E-DMAC has the following features:

•

The load on the CPU is reduced by means of a descriptor management system

•

Transmit/receive frame status information is indicated in descriptors

•

Achieves efficient system bus utilization through the use of block transfer (16-byte units)

•

Supports single-frame/multi-buffer operation

Figure 21.1 shows the configuration of the E-DMAC, and the descriptors and transmit/receive
buffers in memory.
