Question

What operation is NOT in an ALU? A: Float ng point arithmetic B: Binary logic ND/OR/NOT C:B t shifting D: integer arithmetic What do the letters in the initial ism ALU represent? Arithmetic Link Unifier B:Arithmetic Logic Unifier C Arithmetic Link Unit D:Arithmetic Logic Unit An ALU performs a l of its operations simultaneously. How does the CPU select which result it wants? A:By writing to RAM B: Through the instruction encoding C: Through a multiplexer D: B triggering the ENABLE bit on the appropriate register The amount of time before the ALU receives input and it produces a valid result is known as what? A: Electron delay B: Time delay C: Slow, piece of crap computer D: Propagation delay If during subtraction, the operands 0011 and 0011 are passed as the two inputs to the ALU, what status flag will be set? A. Carry B: Zero C: Sign D: Overflow E:Parity If two signed integers A 0011 and B 0111 are subtracted through the ALU (A B). which status flag would be set? A.
