8080 Assembly Emulator & System Call Handler

Description

This repository provides an emulator of Intel 8080 architecture with a system call handler. I do not have the ownership of the emulator (8080emu.cpp, 8080emuCPP.h), yet I am sharing here as it is free to do so. The repository also comes with example assembly functions:

• Collatz.asm: Computes the numbers of Collatz conjecture from 1 to 25.
• Facrorize.asm: Calculates the factors of the number given in input.txt
• Palindrome.asm: Checks whether given number in input.txt is palindrome or not.
• ShowPrimes.asm: Calculates the prime numbers from 0 to 1000.

---

• In order to compile the program you only need a g++ compiler.
• To run the program without an error, create two files in the same directory: input.txt and output.txt.
  • As explained above, Factorize.asm and Palindrome.asm functions take the required value from the input.txt, and all the output is written into output.txt
• Convert the .asm files into .com files using the following web site: http://sensi.org/~svo/i8080/
  • Paste the content of .asm file into this site
  • Click on the "make beatufil code" button
  • Download, and place the file ending with .com into the same directory.

Example

After a successfull compilation, run for ShowPrimes:

 $ ./main ShowPrimes.com 0
 $ cat output.txt
 	0
	1
	2 prime
	3 prime
	4
	5 prime
	6
	7 prime
	...

Run for Factorization. Change the content of input.txt as you wish, and after executing check the output.txt!

 $ cat input.txt
 	16
 $ ./main Factorize.com 0
 $ cat output.txt
	1
	2
	4
	8
	16

ToDo:

• Add Microkernel handling multiprogramming, interrupt handling and a bit of memory management.
