This project showcases a custom implementation of the memset function written in RISC-V assembly, integrated with a C program. The memset function is designed to fill a block of memory with a specified value, demonstrating low-level memory manipulation and efficient assembly programming.

• main.c: Contains the main C program that declares and calls the custom memset function.
• memset.s: Implements the memset function in RISC-V assembly, optimized for memory alignment and performance.
• README.md: This file, providing a comprehensive overview, instructions, and insights into the project.

The program performs the following tasks:

1. Declares a 32-byte character buffer in the C code.
2. Calls the custom memset function to fill the buffer with the character 'A'.
3. Prints the contents of the buffer to verify correct operation.

Before running this project, ensure the following tools and environment are available:

• A RISC-V toolchain (e.g., riscv64-unknown-elf-gcc).
• A RISC-V emulator (e.g., QEMU) or access to a physical RISC-V hardware platform.

1. Save the C code in a file named main.c and the assembly code in a file named memset.s.
2. Compile and link the files using the RISC-V compiler: riscv64-unknown-elf-gcc -o memset_program main.c memset.s
3. Run the program: Using QEMU: qemu-riscv64 ./memset_program On RISC-V hardware: ./memset_program

The program will print 32 'A' characters in a single line: AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
