Processor and information processing method

摘要

A processor for performing calculations based on an instruction code, the number of bits of which is not an integer multiple of a byte. The instruction code is divided into higher order bits and lower order bits. The number of the lower order bits is an integer multiple of one byte. A memory stores the lower order bits in a lower order bit storage section and the higher order bits in a higher order bit storage section. The lower order bits and the corresponding higher order bits are read from the memory in the same cycle when generating the instruction code.
