help designing a computer control unit with the given info below.

A digital computer has the following instruction formats 15 12 11 10 9 0 Op-Code Tag Address Memory Reference Instruction Format The tag field bit assignment is as follows: Tag IX mo m1 m2 Description Direct addressing Indirect addressing Indexing addressing 01 10 a)Draw a block diagram for a hardwired control unit that can be used for the above computer. Show all blocks required to generate the various control signals. b) The computer has five cycles: Fetch, Execute, Indirect, Indexing and Interrupt. Draw a flow chart for the first four cycles neglecting the Interrupt cycle (15 is the decoded signal for non-memory reference instructions.)
