Abstract

PURPOSE:To enable the processing in byte unit for fixed memories, by adding 0's to the upper rank of code by the number of bits excessive, when the bit length exceeds 8-bit. CONSTITUTION:The code 8-bit of less is read out and the code bit length is selectively output from output terminals O1-O7 of the fixed memory 13. If the bit length thus loaded is greater than 8-bit, the output of a NOT circuit 18 is zero to make OFF an AND circuit 17 and 0's are output every clock until it reaches 8-bit.
