Suppose that you are working with a CISC machine using a 1.6 GHz clock (i.e., the clock ticks 1.6 billion times per second). This particular computer uses MASM-like instructions with the following timings: ADD reg, mem ADD reg, immed LOOP LabelName ; 7 clock cycles ; 8 clock cycles (i.e., the ADD micro-program has 8 instructions) ; 3 clock cycles Suppose that the following code fragment is used to sum elements of a numeric array. For this problem, assume that memory limitations are non-existent and that there is no limit to the size of the array. MOV MOV MOV _ProcessArray: ADD ADD LOOP ProcessArray BX, ECX, MAX_SIZE ESI, OFFSET list ;initialize array pointer ;initialize sum ;initialize LOOP counter вх, [ESI] ESI, 2 ;Add current list element Move array pointer to next element ;auto-decrement ECX, jump to more if ECX - 0 After initialization, how many array elements can be processed in 2.8 millisecond (ms)? Round your answer to the nearest integer. Note that 1 ms = 0.001 second.

hi can u anwser this qustion plesc ? Consider a Computer which has a memory which is capable of storing 4096 K words and each word in memory can be of size 32 bits. The computer supports a total of “K” addressing modes, and it has “M” computer registers. The computer supports instructions, where each instruction consists of following fields: Mode Operation code Register Register Memory AddressGiven that each instruction will be stored in one memory word, discuss with a suitable diagram the format of instruction by specifying number of bits for each field of instruction. Discuss each field of instruction.Note: Choose your own values for K (number of addressing modes) and M (number of Registers) k=8 m=50

If a microprocessor has a cycle time of 0.5 nanoseconds, what’s the processor clock rate? If the fetch cycle is 40% of the processor cycle time, what memory access speed is required to implement load operations with zero wait states and load operations with two wait states?
Imagine we have a small computer which contains a simplified version of a CPU and RAM. The CPU can execute a single program that is stored in the RAM, and while running the program it can access 3 memory locations: its internal register AL, and two RAM locations that we'll call address 1 and address 2. Since this is a simplified computer it is able to skip some of the steps to access memory that are in our textbook, but accessing RAM still takes longer than accessing AL. The only values this computer is capable of storing in memory are unsigned bytes (8 bit binary numbers), and when it starts running a program all 3 of its memory locations initially contain the value 00000000. Here is a list of all of the instructions our imaginary computer can perform: Write [number] to AL This instruction takes the operand [number], which must be an 8-bit binary number, and puts it into AL. This overwrites whatever was in AL previously. It takes 3 cycles to complete: 1 cycle each to fetch, decode,…

Write an assembly language program that reads a specified number of positive integer inputs from standard input and outputs the largest value that was read. For example, if standard input contains: 5 3 2 7 9 4 The 5 indicates that there will be 5 additional values. Then program should read those 5 additional values and print the largest of them (e.g 9 in this case). One strategy here would be to outline the program in high-level language code and then translate it into assembly code. Be sure to assemble, run and test your program to ensure that it is syntactically correct and that it works correctly. The program should work for any valid input not just the one shown above.
