a) Give four features that were traditionally reserved to RISC architectures?
b) Determine the overall throughput for 21 sequential instructions assuming a four-stage pipeline and each instruction goes through fetch (7 nanoseconds), decode (2 nanoseconds), execute (1nanosecond) and write-back (10 nanoseconds) stages?
c) Calculate the CPI for a hypothetical 1.8 GHz processor with a benchmarked rating of 500 MIPS?
d) Assume a processor with instruction frequencies and costs as follows
• Integer ALU: 50%, 2 cycles• Load: 25%, 5 cycles• Store: 10%, 3 cycles• Branch: 15%, 2 cycles
Determine which of the following three cases will improve or reduce overall performance and by how much:
CASE 1: Reduce Branch cost to 1 cycle and Store cost to 2 cyclesCASE 2: Reduce Load cost to 3 cycles while increasing ALU cost to 4 cyclesCASE 3: Reduce Load cost to 4 cycles
e) Mention one advantage of using DMA over Interrupt-Driven I/O. Give the basic structure of a basic DMA module.

Figure shows the cross-section of an electrostatic problem with translational symmetry: a rectangular coaxial cable. The inner conductor is held at 10 volts and the outer conductor
what would the change after adding a registor paralelly in clampers?
how capacitor works as transducer?
Mode 1 ( 0 By applying a positive output pulse of the pulse width modulator to the transistor Q 1 it gets turned on. An input current in flows through V in Q 1
Direct Addressing In this addressing mode one of the operands is the data stored in the memory. The memory address of the operand is directly given in the instruction
