Abstract:
A protocol for communication through a bus controller to control data transfers between a host processing platform and the data bus of a bit map printer. This protocol is optimized for a data bus which connects a number of ASIC accelerator cards in addition to the printer, disk controller, bus controller and other typical system cards. The basic data transfer cycle transfers eight data words on the bus between ASIC's, I/O devices, printer and any other devices.
