Architecture program usage diagram2/25/2024 ![]() Control Unitįor any microprocessor, control unit is the heart of the whole process and it is responsible for the system operation,so the control unit design is the most important part within the whole design. The barrel shifter is especially created with multiplexers. ![]() The shifttype indicates the needed shift sort of 00, 01, 10, 11 are corresponding to shift left, shift right, an arithmetic shift right and rotate right, respectively. The shift_val input bus is 6-bits, permitting up to 32 bit shift. The quantity by which the register ought to be shifted is contained in an immediate field within the instruction or it might be the lower 6 bits of a register within the register file. This field indicates the kind of shift to be performed (logical left or right, arithmetic right or rotate right). The Shift field within the instruction controls the operation of the barrel shifter. The shifter has different control inputs coming back from the instruction register. This input is coming back from the register file or it might be immediate data. The barrel shifter features a 32-bit input to be shifted. It’s clear that the multiplication finishes only in16 clock cycle. The figure shows the simulation results for the multiplier test bench. Moreover, the runs of 0’s or 1’s within the multiplier factor are skipped over without any addition or subtraction being performed, thereby creating possible quicker multiplication. This treats positive and negative numbers uniformly. Booth Algorithmīooth algorithm is a noteworthy multiplication algorithmic rule for 2’s complement numbers. Fin of the output goes high when finishing. ![]() The multiplication starts whenever the beginning 04 input goes active. The entity representation of the multiplier factor is shown in the above block diagram. The multiplier output is barely 32-Least Significant Bits of the merchandise. ![]() The multiplier factor has 3 32-bit inputs and the inputs return from the register file. The ALU has a 4-bit function bus that permits up to 16 opcode to be implemented. Whereas the foremost significant bit really represents the S flag, the ALU output operation is done by NORed to get the Z flag. The V-bit output goes to the V flag as well as the Count goes to the C flag. Status registers flags modified by the ALU outputs. The primary comes from the register file, whereas the other comes from the shifter. ![]()
