Abstract
PURPOSE: To shorten the time of the information access to the fixed address within the main memory with a small amount of the control storage capacity, by securing the setting of the literal constant address to the storage address register SAR.
CONSTITUTION: The data read out from control storage CS301 is ratched by control storage data register CSDR302 to give control to various areas. Decorder DEC303 functions when the specified pattern emerges at SAR setting field 31. The output of DEC303 is supplied to gate 304 an functions to ratch the contents of literal field 32 to SAR305. Thus, the literal constant is set to SAR with one cycle, and an access is given to the main memory at the next cycle. As a result, an access is ensured to the fixed address within the main memory in a high speed and with a small amount of the CS capacity
