2. Write Microinstructions for machine instruction in the Instruction Set i.e. LDA addr, STA addr, and JN addr of UCS2011 machine.

need solution for questions 1 and 2.

Questions below are based on this example CPU. The case study is also available in Lecture folder of study Material. (Let us name this CPU as UCS2011 for convenience of reference) 12 1898 PC ACC ES MAR ALU EU NF 12 B RAM IR CLK 98 TIT TIT MDR 4 OLK CONTROL NF HLT 16 Control Signals 1. The UCS2011 has 7 machine instructions in its Instruction Set (LDA addr, STA addr, ADD, SUB, MBA, JMP addr, JN addr). Its hardware includes PC, IR, ALU, two registers - AC and B, MAR, MDR, and a Control Unit. The datapath control in the CPU is achieved through 16 different control signals connected to various hardware components. Given below are Boolean expression for two of these 16 controls for designing a Hardwired Control unit: W(memory write) = T5 * STA R(memory read) = T1+T4* LDA Where + means logical OR and * means logical AND Write such Boolean expressions for LD, ED, El and Ll control signals. Also, design the Hardwired Unit for above four control signals using basic logic gates
