You are given a homework processor (HPro) capable of addressing 32 8-bit (1 byte) wide registers. However, it has only 29 physical registers. Register RO, R1 and R31 are not physically implemented. Instead, every read from RO, R1 and R31 will return a constant zero (00000000), constant one (00000001) and all ones (11111111), respectively. Every write to RO, R1 and R31 will go to null (dummy write). Assume that all other registers have initially unknown (X) state (This in fact...

Suppose we add another SRC instruction xor ra, rb, rc that xors the contents of registers rb and rc and stores the result in register ra. Develop a concrete RTN and a control sequence for this instruction. Note that the SRC ALU does not have an XOR operation, so you will have to design it using the AND, OR and other operations.
Assume that the instruction code is 0x00026140 and the content of some of the registers are as follows: $0 = Oxabcdabcd Oxfefebb of $ 1 = $ 2 = Ox12345678 S3 = 0x769affdd ALU operation Instruction Zero ALU ALU Read register 1 Read Read data 1 register 2 Registers Write register Read Write data 2 data RegWrite result ALU operation 000 001 010 011 100 101 110 111 OPERATION ADD SUB AND OR NOR XOR SHIFT LEFT SHIFT RIGHT Assume...
