This project involves designing a stage to implement specified logic micro-operations and constructing a 5-to-32 line decoder using four 3-to-8 line decoders with enable functionality and one 2-to-4 line decoder. Additionally, it includes writing micro-operations for Increment and Skip Zero (ISZ) and Interrupt. The architecture of a common bus system for 30 processor registers with a memory size of 65,536 x 12 bits will be illustrated. We will determine the sizes of various registers (IR, PC, ACC, TR, AR, INP, OUT) and calculate the number and sizes of multiplexers required.

1. Design a typical stage that implement the following logic micro-operation 2. Construct a 5-to-32 line decoder with four 3-to-8 line decoders with enable and one 2-to-4 line decoder. 3. Write microperations for ISZ and Interrupt. 4. Draw the common bus architecture system for 30 processor registers where size of memory is 65, 536* 12. a) What is the size of IR,PC,ACC,TR, AR, INP, OUT and other registers. b) How many multiplexers are required also specify the size of each multiplexer.
