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.
Define Lines Parameters In power system analysis, the parameters of interest when modelling power lines are: inductance, capacitance, series resistance and leakage resistance.
Q. A balanced delta-connected load with a per-phase impedance of 12 + j9 is supplied by a 173-V, 60-Hz three-phase source. (a) Determine the line current, the power factor, th
Question: a) Give the instruction cycle state diagram for a typical Von Neumann machine. b) Give two diagrams to differentiate between a Memory and CPU connections. c) Co
To have the same value of P e , show that E b /N 0 in a coherent-ASK system has to be twice that in a coherent PSK system.
Q. The K map of a logic function is shown in Figure, in which ds denote don't-care conditions. Obtain the SOP expressions.
can you differentiate the alpha,beta and gamma
What is the similarities between a vacuum diode and a triode?
what is the working of thermal transducers?
The circuit is altered by replacing the capacitor, C1 with an inductor of 150mH and left with the switch in position (a) for a long time. At time t=0, the switch is moved from posi
Sign flag Since D 7 bit in the results is 0sign flag is reset. This also shown that the results is positive.
