how to calculate the maximum load voltage of 3 phase halve and full wave rectifier

Q). The unique addresses assigned to the four registers (R1,R2,R3,R4) of the I/O interface are equal to the XX3 , XX7 , XXB and XXF in Hex . Where XX is hex digits equal to your 82 .Show the well labeled external circuit that must be connected between and 12-bit I/O address from the CPU and the CS, RSI, and RS0 Inputs of the Interface

Q) Find the values of the flags (carry ,sign ,zero, overflow) of the processor status register for the given example of two 16 bit no’s in Hex (ABCD + 5678) and draw the circuit diagram also

Q) Explain the difference between RISC and CISC in detail ?

Q)Explain the Register stack organization of 64 locations of stack(0 to 63). take the initial value of the stack pointer is SP = 1F in Hex. Explain the following push and pop instructions through the Register stack organization diagram.

(1) PUSH R9 WHERE R9 = (82) Hex

(2) POP R8 WHERE R8 = (82 + 5 ) Hex for example roll no 64 is having the data in R9 = 64 Hex and R8 is ( 64+5 = 69 Hex)

1. Design a circuit of General register organization in which 2 registers are there from R0 to R1. (a) Perform the following microoperation and explain the operation in the steps through the diagram properly: - SUB R0 ,R0 ,R1 .

(b) Explain the control word as per the register configuration given above

The unique addresses assigned to the four registers (R5, R6, R7, R8) of the I/O interface are equal to the XX3, XX7, XXB, and XXF in Hex. Where XX is hex digits equal to your roll no. (if the student is having to roll no 45 then addresses are 453,457 ,45B, 45F in Hex ) .Show the well-labeled external circuit that must be connected between the 12-bit I/O address bus from the CPU and the CS, RSI, and RS0 Inputs of the Interface.

Find the values of the flags(carry, sign, zero, overflow) of the processor status register for the given example of two 12 bit no’s in Hex (AB7 + DEF) and draw the circuit diagram also. 

Explain the instruction format in detail as per the no of address in the instruction with examples?

Explain the Register stack organization of 32 locations of the stack (0 to 31 ). take the initial value of the stack pointer is SP = 09 in Hex. Explain the following push and pop instructions through the Register stack organization diagram.

(1) PUSH R2 WHERE R2 = XX in Hex

(2) POP R1 WHERE R1 = (XX + 5 ) in Hex where XX is your class roll no , for example roll no 64 is having the data in R2 = 64 Hex and R1=( 64+5 = 69 Hex)
