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.
SIM Set Interrupt Mask Instruction This instruction is used to mask unmask 8085 interrupts and send serial output data. The accumulator is used to load the require data
AC and DC distribution onboard ships
Write a program to count how many from your data set called MYDATA, which is a set of signed single-byte numbers, has positive value and are odd numbers. Save the result in POSOD
The energy consumption for a small factory is given at the end of the brief. a) Three commercial tariffs from an energy supplier are shown below. Using these (or other commercia
Paper is hygroscopic and absorbent. This statement is true or false. Ans: Paper is hygroscopic and absorbent. This statement is true.
Flag Registers Flag register is also an 8 bit register. Out of 8 bit five are defined as flags to indicate status of the accumulator hence it is also called status reg
Guarding Against Loss in Transformers Distribution transformers are expected to convert up to 95-98% of the input power into usable output power. A distribution transformers i
Q. Basic working of optical coupler? The optical coupler is suitable for frequencies in the low megahertz range. The photodiode type shown above can handle only small currents;
Q. A bandpass filter circuit is shown in Figure. Develop a PSpice program and use PROBE to obtain a Bode magnitude plot for the transfer function ¯H(f) = ¯Vout/ ¯Vin for frequency
Q A handbook lists the 60-Hz resistance at 50°C of a 900-kcmil aluminumconductor as 0.1185/mile. If four such conductors are used in parallel to form a line, determine the 60-Hz r
