Abstract
A system and method for providing a control store arrangement in which a single memory having a plurality of memory locations can be used for storing sequences of microinstructions or scratch pad information. The number of storage locations defining the scratch pad area can be increased or decreased as required by assigning tag addresses to a desired number of scratch pad storage locations when the microinstruction routines are being assembled. In this manner, the locations defining the scratch pad areas can be tailored to the particular system operation to be performed. This eliminates the need for modifying the control store circuits to change the size of the control store scratch pad area.
