How would you suggest the counter design be modified so that only decimal count values are displayed?The upper 16 -bit binary count value are displayed on the four seven -segemnt displays as four hexadecimal digits. Hexadecimal values aren't good for human perception. How would you suggest the counter design be modified so that only decimal count values are displayed.Figure Q2(e) shows a programmable logic array (PLA) unit with two inputs, four columns, and three outputs.

Enter the value in the box provided in mV. Round to the nearest mV.Question No. 6 Explain the working of 7-Segment Display. What it can display and how logic reduction is carried out for its operation.Consider the following instruction breakdown that decomposes an instruction into 4 parts: OPCODE DST SRC IMM OPCODE specifies the Operation's CODE. DST specifies a DeSTination register. SRC specifies a SouRCe register. IMM specifies a 2's complement value (that's IMMediately available as part of the instruction).

- 8085 microprocessor went through its manipulation operation in the ALU, the results was transferred on the data bus and status of the results was stored in the flag register for indications . With your knowledge and understanding illustrate a complete bit configuration of 8085 flag register and show the functions of the represented bits in the register.- The stack memory is addressed by a combination of the plus offset. The PUSH and POP instructions always transfer between segment -bit number the stack and a register or memory location in the 8086 microprocessors. For string instructions, DI always addresses data in the segment. The 8086 LOOP instruction decrements register for a 0 to decide if a jump occurs and tests it2. Generate 4x2 Priority encoder truth table and draw logic circuit diagram and schematic. Construct and verify if the circuit prioritizes the highest input only. (You must not use the standard priority encoder ICs included in Circuit Verse)
- A microprocessor has an increment memory direct instruction, which adds 1 to the value in memory location. The instruction has five stages: fetch opcode (four bus clock cycles); fetch operand address (three bus clock cyles); fetch operand (three bus clock cyles); add 1 to operand (three bus clock cyles); and, store operand (three bus clock cyles). By what amount (in percent) will the duration of the instruction increase if we have to insert two bus wait states in each memory read and memory write operation? Repeat assuming that the increment operation takes 13 cycles instead of 3 cycles.An 8085 microprocessor executes "STA 1234H" with starting address location 1FFEH (STA copies the contents of the Accumulator to the 16-bit address location). While the instruction is fetched and executed, the sequence of values written at the address pins A15 - Ag isDesign a 3-bit counter that counts the following sequence: 7,5, 3. 1.0.7, 5. 3, 1, 0, 7. etc. Using the sequential design technique that starts from a state diagram, draw the state table. minimize the logic. and draw the final circuit.
