ust use simple assembly code to do the uestion. 6) Write assembly language code that takes an 8-bit signed number in a register as its input and sign extends the number to 32-bits. The 8-bit signed input will be stored in the least significant byte of the register. The upper three bytes of the input register might contain any value. You may choose any register as the input and output. Sign extending means that the sign bit (bit 7 of the input) is copied to the upper 24-bits in the answer. Examples: input: Ox1F54_E778, output: Ox0000_0078 input: OXOF39 29E2, output: OXFFFF FFE2
