Abstract

One of the most important factors in the performance of a processor or CPU is the time required to access storage. If data cannot be obtained as fast as the processor logic can handle it, then a loss in the potential performance of the system will result. Many schemes have been devised to speed up storage accesses. One prior method used to improve the average access time of storage was to provide a 2-byte-wide data path between storage and the main storage processor (MSP). This technique of getting 2 bytes (or more) for each access is commonplace in the data processing industry. As in many systems throughout the computer industry, the present arrangement includes as part of its design the packaging of storage in increments so that storage can be supplied to users in different sizes.
