Latest Patents

One of Hayakawa's latest patents is for a single-chip microcomputer that features an expandable address area. This invention includes expansion registers E0 to E7, which are added to the existing general registers R0 to R7 built on-chip in an 8-bit CPU. The design allows all registers, including the added expansion registers, to be utilized as a single unit of address data for memory access. The address operation is executed at a unit that includes both the expansion register and the corresponding general register. This innovation reduces the number of executable instruction combinations without significantly compromising data processing ability, thereby minimizing the logical and physical scales of the CPU. The register is enhanced to 32 bits by integrating the 16-bit expansion register with the general registers, allowing for versatile usage in software or hardware applications.
