The 32-bit RISC-V base integer instruction set (rv32i) does not support multiplication and division operations. To deal with this, a compiler may call a function when a multiplication is needed. For example, gcc expects that a function - mulsi3(unsigned int a, unsigned int b) is provided to multiply two integers. A multiplication can be carried out by repeated additions and shifts: unsigned int -_mulsi3 (unsigned int a, unsigned int b) { unsigned int r = 0; while (a) { if (a & 1) { r += b; } a >>= 1; b <<= 1; } return r; } a) Translate the above C code into equivalent RISC-V rv32i assembler code. Comment the as- sembler code to explain how the calculation proceeds. Note that the arguments are passed via the registers a0 (x10) and a1 (x11) and that the result is returned in a0 (x10). b) Does the function need function call prolog and epilog? Explain why or why not. You are invited to use emulsiV to develop and test your assembler code.
Write a assembly code for 8086/8088 that replace the contents of each cell with the sum of the contents of all the cells in the original array from the left end to the cell in question. Thus, for example, if the array passed to the function looks like this: 5 2 9 3 7 then when the function returns, the array will have been changed so that it looks like this: 5 7 16 19 26

PROGRAM 9: hasDuplicatesWrite an HLA Assembly language program that implements a function which correctly identifies whether two or more parameters have identical values and returns a boolean value in AL. Return 1 in AL when two or more parameters are identical; 0 otherwise. In order to receive full credit, you should be preventing register corruption by preserving and then restoring the value of any register your function touches. This rule applies to every register except for EAX which is being used to pass an answer back to the calling code. This function should have the following signature:procedure hasDuplicates( x: int16; y: int16; z: int16 ); @nodisplay; @noframe; Feed Me x: 5Feed Me y: 13Feed Me z: 10AL = 0 Feed Me x: 35Feed Me y: 5Feed Me z: 5AL = 1 Feed Me x: 5Feed Me y: 5Feed Me z: 5AL = 1

There is an application that requires the following hardware: an Intel 8031, a Program ROM of 8Kx8, a Data ROM of 4Kx8 for look-up tables and a Data RAMs of 8Kx8. The memory map of the design: Program ROM should start at address 0000H. Then, the Data ROM should come above the Program ROM. Finally the Data RAM must go to the top of the memory map. There should be no gaps between the memory addresses of the external ROMs. Calculate the address space of the ROMs and RAMs of your design.
Suppose a program segment consists of a purely sequential part which takes 100 cycles to execute, and an iterated loop which takes 400 cycles per iteration. Assume that the loop is dependent on the sequential part, i.e., both parts cannot run in parallel. Also assume that the loop iterations are independent, and cannot be further parallelized. If the loop is to be executed 100 times, what is the maximum speedup possible using an infinite number of processors (as many processors as you could possibly need) compared to a single processor?
