Hex2Bin

The program converts hexadecimal instructions to binary ones.

Details

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.
• x is used to indicate indexed-addressing mode.

Example

Enter the hexadecimal instruction: 03C300
Binary representation: 0000 0011 1100 0011 0000 0000
Opcode: 00000011
Mode: Indexed
Address: 100001100000000
