Abstract

The method described here uses a split bus technique to improve data throughput. In the split bus, address bus, read data, and write data can be transferred independently. When read data or write data bus is used a bus master, other master must wait until the bus becomes empty. But if another bus is empty, by changing transfer type from read to write or write to read, two read cycles or write cycles operate at the same time.
