2.10 Consider the following program: int x = 0, y = 0; co x = x + 1; x = x + 2; // x = x + 2; y = y X; ос (a) Suppose each assignment statement is implemented by a single machine instruction and hence is atomic. How many possible histories are there? What are the possible final values of x and y? (b) Suppose each assignment statement is implemented by three atomic actions that load a register, add or subtract a value from that register, then store the result. How many possible histories are there now? What are the possible final values of x and y?

Select the logic to implement a loop using the LOOPNZ instruction. ECX = ECX – 1 if ECX > 0 and ZF=0 , jump to destination O ECX = ECX + 1 if ECX > 0 and ZF=1, jump to destination EDX = EDX - 1 if EDX < 0 or ZF=0 , jump to destination

Example: The Problem Input File Using C programming language write a program that simulates a variant of the Tiny Machine Architecture. In this implementation memory (RAM) is split into Instruction Memory (IM) and Data Memory (DM). Your code must implement the basic instruction set architecture (ISA) of the Tiny Machine Architecture: //IN 5 //OUT 7 //STORE O //IN 5 //OUT 7 //STORE 1 //LOAD O //SUB 1 55 67 30 55 67 1 LOAD 2- ADD 3> STORE 4> SUB 5> IN 6> OUT 7> END 8> JMP 9> SKIPZ 31 10 41 30 //STORE O 67 //OUT 7 11 /LOAD 1 //OUT 7 //END 67 70 Output Specifications Each piece of the architecture must be accurately represented in your code (Instruction Register, Program Counter, Memory Address Registers, Instruction Memory, Data Memory, Memory Data Registers, and Accumulator). Data Memory will be represented by an integer array. Your Program Counter will begin pointing to the first instruction of the program. Your simulator should provide output according to the input file. Along with…

1.9 Assembly language uses branch instructions to implement loops and selection statements. Explain why a for loop and an if statement in high-level languages represent an improvement on this assembly language technique.

Can you explain please

Answser must be in MIPSzy assembly language. Max of 3 - Branch

Suppose the implementation of an instruction set architecture uses three classes of instructions, which are called A, B, and C. The total dynamic instruction count is 1 x 10^7 and the processor's clock rate is 2.5 GHz. Details for the three classes are given in the table below: Class A B C ΙΑ Complete the following table. Express all answers in scientific notation and round to two decimal places, when needed. Class Instruction Count B CPI 1 2 3 C % of instructions 20% 50% 30% x 10^ x 10^ x 10^ Number of Clock Cycles x 10^ x 10^ x 10^

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
