2. Design a simple microprocessor called Ege-ARM which is a simple 16-bit single-cycle processor that implements a custom instruction set. The processor should consist of the following four main components: • A register file • An Arithmetic and Logic Unit (ALU) • A read-only instruction memory (IMEM) • A read/write data memory (DMEM) This processor has 8 registers (RO-R7) and the program code is stored as NM-bit instructions (NM is a two digit, base ten number with M being equal to the mod 10 of your student number, and N being 2 if M>=2 and being 3 if M<2. Thus, NM is a two digit number in the interval [22,31]) in the IMEM. The processor implements three types of instructions, an instruction format example for 22-bit instructions is shown at Table 1. Some instruction examples are shown at Table 2.
