3 – Write the following sequence of code into the RISC-V assembler. Assume that x, y, and z are stored in registers x18, x19, and x20 respectively.

z = x - 2;

x = z +4 - y;

Solutions

Expert Solution

Given assumption is that x, y, and z are stored in registers x18, x19, and x20 respectively.

z = x - 2;

x = z +4 - y;

The code in RISC-V has been given below:

addi x20, x18, -2 // z=x-2
addi x20, x20, 4 // z=z+4
sub x18, x20, x19 // x= z-y;
HLT

Output:

An output with online RISC-V interpreter with x18=15 and x19=6 has been shown below. The final register contents are: x18=11, x19=6, x20=17.

Write the following Python code: A string X is an anagram of string Y if X can be obtained by arranging all characters of Y in some order, without removing any characters and without adding new characters. For example, each of the strings "baba", "abab", "aabb" and "abba" is an anagram of "aabb", and strings "aaab", "aab" and "aabc" are not anagrams of "aabb". A set of strings is anagram-free if it contains no pair of strings which are anagrams...

Write a program in "RISC-V" assembly to convert an ASCII string containing a positive or negative integer decimal string to an integer. ‘+’ and ‘-’ will appear optionally. And once they appear, they will only appear once in the first byte. If a non-digit character appears in the string, your program should stop and return -1.

A single product (A) moves in sequence through 3 operations: V, W, and X. The processing time at each operation (in minutes per unit) is 10, 20 and 10 respectively. If the process batch size and the transfer batch size are both 100, what is the total amount of time required to process the batch? If the transfer batch size is reduced to 50, now how much total time will be required to complete the batch (do not worry about...
