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.
Design a logic circuit when to provide an output when any two or three of four switches are closed.
Switched Mode Power Supply (SMPS) Switching mode power supply converts an unregulated DC voltage to a regulated DC output voltage . SMPS stands for switched mode power
In a 3-stage continuous ultrafiltration process, a solution is concentrated from 5 gm/Liter to 50 gm/Liter of protein. The final retentate is to have a flow rate of 1000 L/hr. The

RIM is Read Interrupt Mask. Used to ensure whether the interrupt is Masked or not. SIM is Set Interrupt Mask. Used to mask the hardware interrupts.
Problem: The current voltage characteristic [ ID versus VD] of a semiconductor diode for VD > 0 [forward bias] is given in Figure Under reverse bias conditions [VD Fi
Question: Consider the circuit shown in Figure. There is no initial energy stored in the circuit until time t=0 when the switch is closed. (i) Transform the given circ
