Problem 4: Easy-to-follow Assembly Instructions The conversion of a mnemonic instruction to its binary representation is called assembly. This tedious process is generally delegated to a computer program for a variety of reasons. The first is that it alleviates the need to keep track of all the various bit encodings for each type of instruction. A second reason is that frequently the precise encoding of an instruction cannot be determined in a single pass This is particularly true when referencing labels. In the following exercises, you will get a taste of what the task of translating from assembly to machine language is like. Give binary and hexadecimal encodings for the following instructions: Hex Binary A. B. C. D. E. F. EOR R4, R3, R11 AND R10, R9, R7 ADC R1, R0, #599785472 MOV R9, R10 MVN R3, #6144 ORR R9, R2, #171
