Abstract
PURPOSE: To reduce an overhead generated due to control bit processing by outputting stored control bits, justified to one side, after shifting them by a fixed number of bits with stored initial address information.
CONSTITUTION: With inputs to assigned-bit register 5 that assigns the kind of memory operation and to register 6 that sets three low-order bits of memory length, memory-control-bit generating circuit 8 generates basic control bits justified to the left as many as eight bytes and with eight basic control bits 18 and an input from memory position rgister 7 that sets three low-order bits of the initial address of the memory, shifter 9 shifts basic control bits to the right. The former half of eight bits of the output of shifter 9 is input to memory-control-bit register 10, and the latter half of eight bits is input to buffer-memory-control-bit register 11, so that the contents of register 10 will be transferred to memory unit MEM together with memory data.
