Objective:

Translate C code involving global arrays and variables into RISC$-$V assembly within the

main function.

Develop an understanding of global data manipulation and memory addressing in assembly.

Apply assembly instructions to modify and evaluate global data directly.

Assignment:

Write RISC$-$V assembly code within the main function that replicates the functionality of the

provided C code examples, emphasizing manipulation of global data.

Task $1$: Initialize and Modify a Global Array

C Code:

int globalArray$[3]=\{10,20,30\}$;

int main$()\{$

globalArray$[1]=50$;

return $0$;

$\}$

Expected RISC$-$V Assembly:

$1.$ Define and initialize a global array with three integers within the main function.

$2.$ Modify the second element of the array to $50.$

$3.$ End the program gracefully.

Task $2$: Calculate the Sum of Elements in a Global Array

C Code:

int globalNumbers$[4]=\{5,15,25,35\}$;

int main$()\{$

int sum $=0$;

for $($int i $=0$; i $<mtext></mtext><mn>4</mn>$; i$++)\{$

novabrains.ai

sum $+=$ globalNumbers$[$i$]$;

$\}$

return $0$;

$\}$

Expected RISC$-$V Assembly:

$1.$ Initialize a global array and a sum variable.

$2.$ Sum the array elements using a loop structure.

$3.$ Terminate the main function correctly.

Task $3$: Determine the Minimum Value in a Global Array

C Code:

globalData$[5]=\{40,30,20,10,50\}$;

int main$()\{$

int min $=$ globalData$[0]$;

for $($int i $=1$; i $<mtext></mtext><mn>5</mn>$; i$++)\{$

if $($globalData$[$i$]$ min$)\{$

min $=$ globalData$[$i$]$;

$\}$

$\}$

return $0$;

$\}$

Expected RISC$-$V Assembly:

$1.$ Define and initialize a global array and a variable for the minimum.

$2.$ Implement a loop with conditional logic to find the minimum value.

$3.$ End the program in the main function properly.Lab: Manipulating Global Arrays and Variables in RISC$-$V Assembly

performed.

Ensure that all global data is appropriately defined and manipulated.

Confirm that your assembly code effectively replicates the operations outlined in the C code,

including program termination.
