Identity the following statements as true or false (3% for each queston) 16. The closer devices to a centralized bus arbiter gets aways the prionity last 17. 4 bits are required to address 4 words where each word has 3 bytes 18. 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 19 Gates are not manufactured or sold individually but rather in units called Integrated Circuits, often called ICs or chips 20. The time interval between the corresponding edges of two consecutive puises is known as the clock cycle time 21. Latches are used to build memory 22. Registers cannot be read and written at high speed since they are internal to the CPU 23. The Instruction Register (IR), which holds the instruction currently being executed 24. Pipeline is an example of parallelism and has 3 stagers 25. The half adder has two inputs and one output 26 (5%) What function does the following machine instruction perform in ALU? 000000000 000 00001100 000000000 000 0000 1. (1096) Build a truth table to show that X-NOT X AND Y) OR (X AND Y) 2, (10%) A pipeline is designed with 5 stages having execution times respectively as 3ns, 3ns, 2ns, 5ns and 5ns. What is the total time it will take to execute 1000 instructions
