So maybe the problem is is that I keep putting this question under computer science, so I'm going to try and put this under electrical engineering and see if you guys know how to solve this, (this class type question is computer logic and organization but im going for my bachelors is in computer science which is why I kept putting it under computer science)

Design a tiny control unit for a one-address machine. In your design you must show the Instruction Register (IR) fields (op-code, addr). The op-code is 2 bits and is connected to a decoder. The outputs of the decoder are numbered 0, 1, 2, and 3 and each one of them is associated to a different instructions (0 = LOAD, 1 = ADD, 2 = STORE, and 3 = SUB). A 3- bit ring counter is used to execute the instruction in three clock ticks (T1, T2, and T3). In your design you must show IR, the decoder, and ring counter for the execution of the instruction STORE. Show, (using a box with a label for each computer component), the part of the computer that receives signals T1, T2, and T3.
