Abstract
An integrated circuit, slave microprocessor with its bus protocol is described. The slave unit may be activated by either a master microprocessor or a DMA controller. When activated by the DMA controller, handshaking signals between the controller and slave microprocessor permit the transfer of data between these units without intervention by the master microprocessor. Unique flags permit the master processor to readily determine the status of the slave microprocessor.
