2. Write an 8085 program to add two 8-bit numbers A1 and CO. Then store the final result into the Accumulator and show the output in sim8085.

please explain the reasoning for choosing the specific multiplexer and other steps DON NOT copy-paste from other sources. Thank you for your help!

The following figure shows the four-bit Adder-Subtractor. Here A = 2(0010), B = 5 (0101) and M = 0. Select all the TRUE statements.   a The circuit is working as an adder. b The circuit is working as a subtractor. c The output result S = 1100. d The output result S = 0111.

the output for printsub3 should be in this order: a b c d ab bc cd abc bcd abcd  and output for printsub4 should be in this order: abcd bcd abc cd bc ab d c b a

please help with both

Write C statements: If the data in PORTB is odd, toggle the data and then send to PORTD; otherwise, copy the data to PORTC and then the data will be send out one bit at a time through RC7, and MSB of the data will go out first.

Create a Verilog code, Synthesis, and a testbench of 8-bit Accumulator. Show the result using seven segment display.
