1. Given Hexadecimal EDCC₁₆

Detail steps are required.

a) What is the binary representation?

b) What is the negation of EDCC in HEX?

c) Convert it to decimal number if this is a 2s-complement signed binary representation in 16-bit register

d) Convert it to decimal number if this is an unsigned binary representation in 16-bit

2. Suppose we have 3 arrays A, B, and C, array As base address is in $S3, Bs base address is in $S4, Cs base address is in $S5. You can only use two temporal registers $t0 and $t1. Convert the following code into MIPS assembly language code. Suppose every array element occupies 1 word in MIPS (32 bits).

A[21] = B[2] + C[16];
