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;

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.

In Assembly Code write an assembler code (Fibonacci.s) and show results The Fibonacci Sequence is a series of integers. The first two numbers in the sequence are both 1; after that, each number is the sum of the preceding two numbers. 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, ... For example, 1+1=2, 1+2=3, 2+3=5, 3+5=8, etc. The nth Fibonacci number is the nth number in this sequence, so for example fibonacci(1)=1, fibonacci(2)=1, fibonacci(3)=2, fibonacci(4)=3, etc....

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...

Convert the following C program into the RISC-V assembly code. You should look up a table to convert the lines manually and you can use "ecall" when appropriate (Don't make it too complicated than it needs to be): #include int main() { int x = 30, y = 17; printf("x * y = "); printf("%d\n", x*y); return 0; }
