ABSTRACT:
A data processing method of operation and system uses a processor, an addressable data memory, and an addressable data extension read-write memory. As a data word is written into and read out of the data memory, a data extension associated with the data word may be simultaneously respectively written into and read out of the extension memory. The extension supplements the data word to effectively double the length of the data word. An address bus and control bus cause the simultaneous inputting/outputting of data and extensions to and from the data memory and extension memory respectively. An intermediate storage means is used for inputting and outputting extensions to and from the extension memory. The intermediate storage means includes an interface adapter which interfaces the extension memory to the processor as though the extension memory is a peripheral I/O device. An INTERRUPT is used to alert the processor of the reading of an extended data word.
