8051_C program definition

Fully explain what the program does by providing manual walk-through i.e. Step through the program by hand indicating state of variables, inputs and outputs at each statement. Give a general overview of what the program does using Layman terms. (See attached word document for program details)

Loop Unrolling Codes

Please check my work and let me know if I did this correctly. If not please show what is wrong and give me the correct answer and the proper way to get the answer. Question: Which are/is the 2 times loop unrolling code for the loop below? Loop: ADD R1, R2, R3 SUBI R4, R4, 1 BNEZ R4, Loop a) Loop: SUBI R4, R4, 1 ADD R1, R2, R3 BNEZ R4, Loop b) Loop: ADD R1, R2, R3 SUBI R4, R4, 1 ADD R1, R2, R3 SUNI R4, R4, 1 BNEZ R4, Loop c) Loop: ADD R1, R2 R3 ADD R1, R2, R3 SUBI R4, R4, 1 BNEZ R4, Loop d) Loop: ADD R1, R2, R3 ... click for more

The 8086 Microprocessor Operating Systems and System Interrupt services

Please help me write a program that will display the hex code for any key, or key combination, that is pressed on the keyboard. Display the key code in the center of the screen. For instance, if the key number 0 is pressed, display a 30 on the center of the screen. This code must be for the 8086 chip and work with the A86 assembler.

8086 Microprocessor Operating Systems and System Interrupt Services

If your computer is equipped with a cga adapter or above, write the message "this is page1" on page 1, "this is page 2" on page 2 and so on until the message "this is page 7" is written to page 7. center the messages on the pages in exactly the same place. hav the program alternate the messages and determine if you can detect the fact that each message is rewritten. have the program terminate and return to dos when the q key is pressed. This must be a program for the 8086 chip and be able to assemble it with a86 assembler. Leave message with how many credits needed.
