Using 8-bit 2’s complement math, Subtract 17 from 8 (8-17)
VHDL structural code please
Design an 8-bit add/subtract in Verilog AND VHDL using any of the coding styles and language features covered so far in modules 8 and 9. When AS Sel0 it performs an addition, else when AS Sel 1 it performs a subtraction. OpA and OpB are assumed to be signed, 2's-Complement numbers. Hint: Bit-wise XOR AS Sel with OpB before adding it to OpA- see lecture notes Op87.0Add/ Subtract Vout
5. Add 21+27 using 6-bit signed binary numbers.
P7.20. Perform these operations by using eight-bit signed two's-complement arithmetic: a. 17 10 + 15 10; b. 17 10 - 15 10; C. * 33 10 - 37 10; d. 15 10 - 63 10 : e. 49 10 - 44 10.
Please convert the 4-bit, signed value to it's unsigned magnitude (absolute value) in binary and it's signed decimal value: Ob0101 Binary magnitude: Ob Signed decimal value:
Ouestion 8 Perform the following subtraction in binary system (using 8-bit signed number representation) and express the result in decimal: (a) - 33 + 71 (b) - 105- 90 (c) -80 +59
Consider a negative number detector which accepts a 5-bit signed-magnitude binary number A as input and outputs 1 if and only if A is a negative number. (hint: A can be written as A4A3A2AAo) (3096) Implement this circuit using: a. One AND gate and one OR gate b. One 4-to-2 priority encoder with valid bit
Please convert the 4-bit, signed two's complement value to it's unsigned magnitude in binary and it's signed decimal value: 0b1100
Using single bit Full Adder (FA) blocks (as shown below) and
required gates, construct a 6-bit Adder/Subtractor for signed
numbers.
Use the signed two’s complement system for the signed
numbers.
Verify your design for the following addition and subtraction by
specifying A as A5A4A3A2A1A0 and B as B5B6B3B2B1B0, determining the
inputs to the FAs and their outputs and showing that the outputs
correspond to the correct results:
a) A-B with A = -13, B = +20 (5 points)
b) A+B...
(a) Subtract (78) in base 10 from (97) in base 10 using 2's complement arithmetic , (b) Divide the number (221) in base 10 and (17) in base 10 by converting the original decimal number to its 8-bit equivalent using straight binary.
