TRANSLATE C CODE TO MIPS

In this assignment, a palette of eight such values are created and stored in memory. The intensity of a pixel is defined as: I = (R+G+B) /3

Objective: For this assignment, you will write two programs, one in C and one in MIPS. There are three key tasks each color matching program needs to be able to do: 1. Unpack a color by pulling the individual unsigned 8-bit red, green, and blue component values from the lower 24 bits of a 32-bit integer. Hint: in C, the shift (>) and mask 2. (&) operators may be useful; in MIPS, the load byte instructions may be helpful. Note that the Misasim memory implementation is little endian (the least significant byte is located at the word address). 2. Compute the difference in intensity between two given unpacked colors using the defini-tion of intensity given above. 3. Use nested loops and conditionals to orchestrate the comparison of all pair
