Introduction Encoding is the procedure used in computers to convert a string of letters (letters, numbers, punctuation, & specific symbols) into a format that is specifically designed for efficient storage or transmission. The process of converting an encoded format into the original string of characters is known as decoding.Solution: All instructions can put together with their needed operands if length of the variable opcodes are utilized. then, we will be able to find this without the use of encding by the enum method. 1) 3 2-address inst: 3*25*25 =30722) 30 1-address inst: 30*25=9603) 45 1-address inst:45Total=3072+960+45 =40774) 212==4096, and 4077<4096So, it must be possible Now, let's split down: 3 inst=2bits with 1 additional encoding+5 bits * 2 addresses=12 bitsSo, 00+2*5 bit addr0110Next set will have to employ the 4th (11) value to differentiate from the starting 330 inst fits in 25=32 , so now we have 2 remaining=2 bits+5 bits opcode+ 5 bits addr=12 bits11+00000+5 bit addr11+11101+5 bit addrUtilizing the remaining two encodings (like in 11 + 11110 and 11 + 11111)plus the remaing bits to represent the 0 adress instructions.45 inst < 26 (64), so unique bits for opcode11 + 1111 + 6 bits Hence, they all can be encoded.
