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. A three-phase ac motor, used to drive a draft fan, is connected to a 60-Hz voltage supply. At noload, the speed is 1188 r/min; at full load, the speed drops to 1128 r/min. (a
what is the equation for rc phase shift oscillator?
A three-phase transposed line is composed of one conductor per phase with flat horizontal spacing of 11 m as shown in Figure 1(a). The conductors have a diameter of 3.625 cm and a
Define Time and Shift Invariant? Time and shift invariant means that the system characteristics and shift do not change with time, i.e. the system output is independent of the
Q. Explain the procedure of Binary to Hex Conversion? It is simple to convert from an integer binary number to hex. This is completed by: Break the binary number int
Write three m ?les to generate M ensemble members of length N, for the following three random processes: i) function v=rp1(M,N); a=0.02; b=5; Mc=ones(M,1)*b*sin((1:N)*p
Electromagnetic torque The torque is given by the force on the armature winding multiplied by its radius. Force on a conductor in magnetic field B is: F=B.I.L so, T=B
