Question
Identify the following statements as true or false (3% for each question). 19. The closer devices to a centralized bus arbiter gets always the prionity last 20. 4 bits are required to address 4 words where each word has 3 bytes 21. The simple comparator takes two inputs, A and B, each of length 4 bits, and produces a O if they are equal and a 1 otherwise 22. Gates are not manufactured or sold individually but rather in units caled integrated Cirouits, often called ICs or chips 23. The time interval between the corresponding edges of two consecutive pulses is known as the clock cycle time 24. Latches are used to build memory 25. Registers cannot be read and written at high speed since they are internal to the CPU 26. The Instruction Register (IR), which holds the instruction currenty being executed 27. Pipeline is an example of parallelism and has 3 stages 28. The half adder has two inputs and one outputExplanation / Answer
19.False: closest device gets high priority
20.False:To address 4 words we need 2 bits(00,01,10,11)
21.False( produces 1 if equal and produces zero if not equal)
22.True
23.True
24.True
25.True
26.True
27.False: Pipeline is an example of parallelism but it has 4 to 5 stages
28.False: Half adder has two inputs ( bits to be added) and two outputs(sum and carry)
