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.
The goal of this project is to model a system and to design a controller for the system so that the closed-loop system performs satisfactorily.

Actual Loading Method This method is employed commonly for testing of single phase meters within laboratory. On a meter testing bench that is equipped along with several taps
Q. What is thermal runaway. The problem of self heating arises due to dissipation of power at the collector junction. The leakage current ICBO is extremely temperature dependen
CMOS processes: The low-performance "lateral" bipolar transistors occasionally employed in CMOS processes are sometimes designed symmetrically, i.e., with no distinction betwe
