ABSTRACT:
A novel microprocessor architecture can be easily interfaced with various peripheral devices. The microprocessor is generally made up of a CPU core, a RAM, a ROM and an input/output option. The RAM adjoins one edge of the CPU core and the ROM adjoins the opposite edge of the CPU core. The input/output (I/O) option adjoins a third edge of the CPU core and the parallel edges of the RAM and ROM. The input/output option is adapted to allow interfacing with various peripheral devices. The CPU core comprises CPU and segments commonly used to form a complete microprocessor. Such common segments may include a RAM address register facilitating access to the CPU by the peripheral devices.
