ABSTRACT:
An apparatus and methods are provided for pre-compressing data to be sent to a peripheral device in a computer system, sending the data to the peripheral device as a compressed data stream, and decompressing the data for use in the peripheral device in a real-time format. In a preferred embodiment, a unique peripheral device controller is provided having a data handling and decompression pipeline for receiving and decompressing an incoming compressed data stream in concert with a state machine for sensing the states of elements of the peripheral device, and for providing the decompressed data stream to data-using elements of the peripheral device. The peripheral device can be any device for which large amounts of data are typically needed, including, but not limited to printers, video displays, robotic driving devices, and data recording and media writing devices. Alternative methods are disclosed for compressing and decompressing data in systems according to the invention.
