We have three 4-bit registers A, B, and C available, each with the standard "Load" input. When "Load" is at 1, then 4-bit data available on the input of a register is loaded into the register at the next rising clock edge. Assume registers A and B are already loaded with 4-bit data representing unsigned numbers. We need to design the data path for the following case: If value stored in register A is an odd number, then register C should be loaded with the sum of values present in A and B registers; else, register C should be loaded with binary value 0000. Your design may include standard logic gates, adders, and multiplexers.
A) Identify dependencies add R3, R3, R4 sub R4, R2, beq RO, R2, end addi R4, R4, 12 end: R2, R3 B) insert NOPS add R3, R3, R4 sub R4, R2, R3 beq RO, R2, end nop addi R4, R4, 12 C) reorder for performance
How would i create this chip in hdl (hardware description language) HiLoMux - This has one 8-bit input bus, in, and one 4-bit output bus, out. Alsopresent is a sel input, which is used to select what appears on out. Ifsel is false, then out should contain the lower 4-bits of in (i.e. in[0],in[1], in[2], in[3]). If sel is true, then out should contain theupper 4-bits of in (i.e. in[4] mapped to out[0], in[5], mapped toout[1], etc.). In other words, the HiLoMux can be used to select anibble from a byte… this is what ive got so far CHIP ALUcore { IN a[4], b[4], carryIn, sums, ands, xors, ors; OUT out[4], carryOut; PARTS: }

Consider the code below that runs in the five stage pipeline that does not handle any data hazard (no forwarding and no write/read register in the same cycle). Add NOP operations so that the code runs correctly. You may draw a time diagram to help you answer the question. ADDI X1, X2, #3 ADD X3, X1, X2 ADDI X4, X1, #13 ADD X5, X3, X2
