1. Answer True or False to the following statements --(36%) (A) Overflow cannot occur when subtracting operands with same signs. (B) When implementing the hardware for 32-bit integer division, the remainder and the quotient can share the 64-bit space for better utilization. (C) There is always a trade-off between precision and range when representing a floating-point number because a fixed size is used. (D) In computer arithmetic, floating-point addition may not be associative; that is, x+(y+z) != (x+y)+z. Se 9 (E) The register is considered as a type of combinational elements. De (F) When designing the processor, the control signals RegRead and Reg Write are used for controlling the data access of register files. (G) Designing the control is more complicated than designing the datapath since it requires an understanding of how all the components in the processor operate. (H) In the pipelined processor, all control signals can be immediately set after the current instruction is decoded in the 2nd stage. - (1) Increasing the depth of pipeline (i.e., number of stages) without balancing the cost of each stage may reduce the overall performance. The CPI value of an ideal pipeline processor is 1.0. 1 -> (K) Pipelining increases throughput and reduces individual instruction execution time. (L) Pipeline bubbles cause loss of performance since that a number of pipeline stages are left empty. UULIN e
