Question:
(a) Comment on the general structure of the IAS Computer, illustrate your answer using a diagram.
(b) (i) Define CPU time.
(a) (ii) A program runs in 10 seconds on a computer A, which has a 100 MHZ clock. A designer has to build a machine B that will run the same program in 6 seconds. The designer has determined that a substantial increase in clock rate is possible, but this will affect the rest of the CPU design, causing machine B to require 1.2 times as many clock cycles as machine A for this program. What clock rate should the designer target?
(c) Explain what is meant by a "bus". Name the two types of buses and give a brief description of both.
(d) Explain with the help of a diagram how to accommodate interrupts in an instruction cycle.
1. (e) In respect of computer disks, explain the terms: (i) Sector, (ii) Track, (iii) Cylinder.
VuGen have two options to help debug Vuser scripts-the Run Step by Step command and breakpoints. The Debug settings in the Options dialog box permit us to verify the extent of the
What are overlays? To enable a process to be larger than the amount of memory allocated to it, overlays are used. The idea of overlays is to keep in memory only those instructi
Write "heterogeneous" functions If a program uses simulated, dynamically allocated multidimensional arrays, it becomes possible to write "heterogeneous" functions which don't h
Why is Translation Look-aside Buffers (TLBs) important? The implementation of page-table is completed in the following manner: Page table is maintained in main memory.
Draw the ISDN address structure and explain how the addressing works? Address Structure: The ISDN address structure is demonstrated in figure. ISDN number part has a maximum
an asyncronous sequential circuit is described by the the exitatio function and the output function y=x1x2''+(x1=x2'')y output function z=y a)draw the logic diagram of the circuit.
Q. Show the fundamental process of instruction execution? The fundamental process of instruction execution is: 1. Instruction is fetched from memory to CPU registers (calle
Q. Observations of High Level Language Program? Observations Integer constants appeared nearly as frequently as structures or arrays. Most of the scalars were foun
How many address bits are required to represent 4K memory ? Ans. 12 address bits are required for representing 4K memory, as 4K = 2 2 x 2 10 = 2 12 Therefore 1K = 1024
Subtract the given number using 1's complement 11011 - 11001 Ans. 11011 - 11001 = X - Y X = 11011 1's complement of Y = 00110
