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.
