a) Convert 89806910h from machine language to its corresponding assembly language. Show all of your workings.  (b) Suppose the instruction MOV DI, [BP+42h], appears in a program. What is its machine language for the given instruction?

In generall, computers think in terms of numbers (i.e. binary data). Thus, any operation performed in the computer must be done using either mathematical or logical operations. Given this inherit limitation of computers, what is the compare instruction actually doing when we, as assembly programmers, provide two numbers for it to "compare"? Furthermore, what assembly instruction is similar to the compare instruction? How are the two instructions different?

Write an assembly code to assign the register BX with 4014H, and register DX with 4028 H. Move the content of BX to DX, und verse versa. Then, copy the now value of low content for BX and DX .to memory location [2131 H], and [2139H]

Provide the format and assembly language instruction for the following hex values Address 1001: 03

Suppose that we are developing a new version of the AMD Barcelona proces- sor with a 4 GHz clock rate. We have added some additional instructions to the instruction set in such a way that the number of instructions has been reduced by 15% from the values shown for each benchmark in Exercise 1.12. The execution times obtained are shown in the following table. a. Name Execution Time (seconds) Reference Time (seconds) bzip2 700 9650 SPECratio 13.7 1.13.2 [10] In general, these CPI values are larger than those obtained in previous exercises for the same benchmarks. This is due mainly to the clock rate used in both cases, 3 GHz and 4 GHz. Determine whether the increase in the CPI is similar to that of the clock rate. If they are dissimilar, why?

Consider a system in which Data and Code are distinct. When necessary, the CPU acquires instructions or data using two base-limit register pairs. Data and instructions should be kept separate. By default, this pair is read-only, allowing several users to share the programme. This method should be compared to others.

E In the following code block(Reference:Q11), you will a set of assembly instructions with corresponding line numbers (line numbers are for informational purpose only and they are not part of the source code). 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 mov edx, 5 dec ecx jmp LABEL1 mov eax, 1 LABEL1: mul edx jmp ecx mov edx, 0678h sub edx, eax jmp DWORD PTR [edx] neg ebx add ecx, ebx mov eax, 0 For each of the conditions/scenario listed below, indicate the corresponding line number (that cause or is associated with the condition/scenario). Enter 0 (Zero) if the condition is not caused by the block of code. 1) Memory indirect jump: type your answer... type your answer... type your answer... type your answer... 2) Register indirect jump: 3) Relative short jump: type your answer... 5) Two's complement type your answer... 4) Relative near jump: 6) Unreachable code

Consider the instruction fields below: Op= 0, rs= 17, rt= 3, rd= 4, shamt= 0, funct= 39 Provide the assembly language instruction in correct format.The grader is formatted, so please note the small letters, spaces, commas, dollar signs, etc. like the examples below. instructions and register names use small letters, hex digits (A,B,C,D,E,F) are capital, ALL 16-bit immediate values should be represented in hex, with a Ox prefix and 4 hex digits like the examples below addi $t0, $s1, OX00A2 Iw $s2, 0X40E2($a2)

As part of the von Neumann architecture, the a) processing unit and b) programmer counter serve which of the following?
