7.List the steps needed to executed the machine instruction

Add LOCA,R0

in terms of transfer between the components shown in following figure (pls refer to figure 1.3 in text book) and some sample control commands. Assume that the instruction itself is stored in the main memory at location INSTR and that this address is initially in register PC. The first two steps might be expressed as:-
i. Transfer the content of register PC to register MAR
ii. Issue a Read command to the main memory, and then wait until it has transferred the requested word into register MDR.

remember to include the steps needed to update the content of PC from INSTR to INSTR+1 so that the next instruction can be fetched.

answer

Transfer the contents of register PC to register MAR
Issue a Read command to memory, and then wait until it has transferred the requested word into register MDR
Transfer the instruction from MDR into IR and decode it
Transfer the address LOCA from IR to MAR
Issue a Read command and wait until MDR is loaded
Transfer contents of MDR to the ALU
Transfer contents of R0 to the ALU
Perform addition of the two operands in the ALU and transfer result into R0
Transfer contents of PC to ALU
Add 1 to operand in ALU and transfer incremented address to PC


8. What is word length? p 22
9.Explain the difference between Big-endian and Little-endian assignment. p25
10. Explain the following expression:- p 27
i. R1 <-- [LOC]
ii C=A+B
iii. C <-- [A] +[B]
iv. Add A,B,C


11. Consider the following figure (pls refer to figure 3.1 in textbook). Explain the function of following register:-

"Hari Kekasih"

Adakah anda merayakan hari kekasih / Valentine's Day. Jika anda beragama islam- perbuatan tersebut adalah ditegah. Fatwa Kebangsaan telah di keluarkan, dan berikut adalah keratannya..

"Muzakarah Jawatankuasa Fatwa Majlis Kebangsaan Bagi Hal Ehwal Ugama Islam Malaysia Kali Ke-71 yang bersidang pada 22-24 Nov 2005 telah membincangkan Hukum Orang Islam Menyambut Perayaan Valentine's Day. Muzakarah berpandangan bahawa ajaran Islam amat mengutamakan kasih sayang dan tidak ada hari tertentu di dalam Islam bagi meraikannya.

Oleh itu, Muzakarah bersetuju memutuskan bahawa amalan merayakan Valentine’s Day tidak pernah dianjurkan oleh Islam. Roh perayaan tersebut mempunyai unsur-unsur Kristian dan amalannya yang bercampur dengan perbuatan maksiat adalah bercanggah dan dilarang oleh Islam."

Assignment BCS1303

1. 1. Briefly explain the basic functional units of a computer.

2. 2.Explain the connections between the processor and the main memory

3. 3.Lists seven system software functions.

4. 4.A processor cache as shown below is used in most computers to reduce program execution time. Suppose that execution time for a program is directly propotional to instruction access time, and that access to an instruction in the cache is six time faster than access to an instruction in the main memory. Assume that an instruction is found in the cache with probability 0.9, and also assume that if ann instruction is not found in the cache and it must first be fetched form the main memory to the cache and then fetched from the cache to be executed. Compute the ration of a program execution time without the cache to program execution time with the cache. This ratio is usually defined as the speedup factor resulting from the presence of the cache.

5. 5.If the size of a cache is double, assume that the probability of not finding a requested instruction there is cut in half. Repeat question 4 for a double cache.
