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.
Explain Magnetostriction. Magnetostriction: If ferromagnetic materials are magnetized a small change of dimensions of the material obtains place. There is a small extension alo

How can I get an oscillator to genarate a sinusoid instead of a triangle wave
Q. A BJT is biased by the method shown in Figure. If V BEQ = 0.7V, β = 100, V CEQ = 10 V, and I CQ = 5 mA, find I 1 , I 2 , and IEQ.
Q. Describe transistor stability parameters The two parameters are · The stability factor ,K · Stability measure,ß1 These parameters determine the transistor stability
Current Source Inverter (CSI) Current source inverter has constant input but it can be adjusted. In CSI the amplitude of output current is independent of load. The lo
