Latest Patents
Lewis W. Brown holds a patent for a data processor input/output controller. This invention is particularly useful as a microcontroller for the transfer of data between a host processor and one or more peripheral input/output devices in a digital data processing system. The I/O controller functions as a subchannel controller, offloading a substantial portion of the subchannel control function from the host processor. It includes a microprocessor that assists and supervises the internal operations of the controller.
Additionally, the controller features an automatic high-speed data bypass mechanism. This allows data to be transferred between the host processor and the I/O device without passing through the microprocessor, thus requiring no intervention during the automatic transfer. The microprocessor can perform other functions, such as presenting interrupts to the host processor and servicing additional I/O commands concurrently with data transfer. This capability is especially beneficial when multiple I/O devices are connected to the controller. The automatic bypass mechanism communicates with the host processor in a cycle steal mode, and a look-ahead mechanism is provided for issuing cycle steal requests more quickly.
