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.
State whether Lamis theorem is applicable for more than three coplanar concurrent forces?
Q. Figure (a) shows the seven-segment array that iswidely used to formthe decimal digits 0 to 9 in LEDdisplays, as indicated in Figure(b). Let the inputs be the four binary digits
Q. Design the high-pass filter shown in Figure (by determining C) to have a half-power frequency of 1 MHz.
Its not essential that a power plant uses only two rectifiers, it depends on the load there at the site and the capacity of the rectifier or SMPS. Assume the load at the site is 12
