The SAB 82258A is an advanced general-purpose fourchannel DMA controller tailored for efficient high speed data transfer between peripheral devices and memories. It is either coupled tightly with a companion CPU (local mode) or working in stand alone applications using the remote mode. The SAB 82258A is unique among DMA controllers providing complete direct .
