Design a datapath that consists of four four-bit, general-purpose registers and one four-bit processor status word (PSW) register. There are four status bits, carry, overflow, sign, and zero; these will be stored in the four bits of the PSW. The PSW must be written for any operation that uses the function unit but not for those that do not. The function unit for the datapath is the same as designed in the previous lab.During a single clock cycle the register file will produce two outputs, A and B. It has the ability to write to a single register on the rising edge of the clock signal but is not required to write to any register. Output A of the register file is connected directly to the A bus that is the input to the function unit. Bus B data can come from the B output of the register file or from constant data that is supplied by the control unit. Bus B is the B input to the function unit.The data input to the register file is from bus D. Bus D receives data either from the output of the function unit or from an external source, such as memory.Provide the datapath control word for the functions specified for the function unit in the previous laboratory and for load and store operations. The load operation will specify the address to read on the A bus and the data will be presented for the D bus. The store operation will specify the address to write on the A bus and the data to be stored will be from the B output of the register file.
Discuss the various ways to include conditional program flow control in 80x86 assembly programming. What are some limitations implementing this flow control when compared to higher level languages

Design a sequential Mealy circuit with two inputs A and B, and output X using JK flip-flops. The circuit produces an output X = 1 when it detects the sequence of either A = 00 or B = 11, otherwise X = 0.
Let us assume that a synchronouse 3 phase alternator produces a no-load line voltage of 13.2 KV. if a load having a lagging power factor of 0.8 is connected to the machine, must the excitation be increased or decreased
a) Draw the state diagram b) Draw the schematic for the logic to implement this circuit using Inverters, AND gates, OR gates and D flip flops. Use the reverse side and additional sheets if needed.
You balanced a pump impeller by placing a 5 gram weight at a radius of 100 mm. The original vibration amplitude was 10 mm/s, and after adding the balancing weight, the vibration is 1 mm/s. The speed of the pump is 1500 rpm and the weight of the im..
