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.

Q. The equations for a two-port network are given by V 1 = z 11 I 1 + z 12 I 2 0 = z 21 I 1 + (z 22 + Z L )I 2 V 2 = - I 2 Z L (a) Satisfying the equations, dev
Q. An antenna has beam widths of 3° and 10° in orthogonal planes and has a radiation ef?ciency factor of 0.6. Find the maximum radiation inten- sity if 1 kW is applied to the anten
Many circuits, particularly amplifiers, use negative feedback (nfb) in order to function reliably. The nfb changes the performance of the circuit to which it is applied, in most ca
Two identical three-phase, 33-kV, wye connected, synchronous generators operating in parallel share equally a total load of 12 MW at 0.8 lagging power factor. The synchronous react

Q. Define Number Systems? A number system, in general, is an ordered set of symbols (digits) with relationships defined for addition, subtraction, multiplication, and division.
Are you able to give a list of factors that could be considered as the transformer''s characteristics?
A 13.8 kV feed er circui t breaker has a 600:5 multira tio curr ent transform er with charact eristics as show n in Figure 5.11. Th e max - imum load on the feed er is 80 A pri mar
