The program converts hexadecimal instructions to binary ones.
All machine instructions on the standard version of the Simplified Instructional Computer have the following 24-bit format:
opcode(8) x(1) address(15)
- The number in the parentheses next to a particular field indicate the number of bits needed to specify the value of that field.
xis used to indicate indexed-addressing mode.
Enter the hexadecimal instruction: 03C300
Binary representation: 0000 0011 1100 0011 0000 0000
Opcode: 00000011
Mode: Indexed
Address: 100001100000000
