# CPPEMU-Compiler This is a compiler for CPPEMU. Please see the [CPPEMU repository](https://github.com/lewisevans2007/CPPEMU) for more information about the emulator. ## Instructions There are many instructions that the emulator can execute. The instructions are as follows: ``` SEL M [HEX] 0x01 Select memory location with the next hex number SET M [HEX] 0x02 Put the next hex number into the selected memory location ADD HM [HEX] 0x03 Add the next hex number to the selected memory location and store the result in the selected memory location SUB HM [HEX] 0x04 Subtract the next hex number from the selected memory location and store the result in the selected memory location MUL HM [HEX] 0x05 Multiply the selected memory location by the next hex number and store the result in the selected memory location DIV HM [HEX] 0x06 Divide the selected memory location by the next hex number and store the result in the selected memory location ``` ``` SET A [HEX] 0x1A Set register A to the next hex number SET B [HEX] 0x1B Set register B to the next hex number SET C [HEX] 0x1C Set register C to the next hex number SET D [HEX] 0x1D Set register D to the next hex number ``` ``` SET AM [HEX] 0x2A Set register A to the selected memory location SET BM [HEX] 0x2B Set register B to the selected memory location SET CM [HEX] 0x2C Set register C to the selected memory location SET DM [HEX] 0x2D Set register D to the selected memory location ``` ``` SET MA [HEX] 0x3A Set the selected memory location to the value of register A SET MB [HEX] 0x3B Set the selected memory location to the value of register B SET MC [HEX] 0x3C Set the selected memory location to the value of register C SET MD [HEX] 0x3D Set the selected memory location to the value of register D ``` ``` ADD AM [HEX] 0x4A Add the value of register A to the selected memory location and store the result in the selected memory location ADD BM [HEX] 0x4B Add the value of register B to the selected memory location and store the result in the selected memory location ADD CM [HEX] 0x4C Add the value of register C to the selected memory location and store the result in the selected memory location ADD DM [HEX] 0x4D Add the value of register D to the selected memory location and store the result in the selected memory location ``` ``` SUB AM [HEX] 0x5A Subtract the value of register A from the selected memory location and store the result in the selected memory location SUB BM [HEX] 0x5B Subtract the value of register B from the selected memory location and store the result in the selected memory location SUB CM [HEX] 0x5C Subtract the value of register C from the selected memory location and store the result in the selected memory location SUB DM [HEX] 0x5D Subtract the value of register D from the selected memory location and store the result in the selected memory location ``` ``` MUL AM [HEX] 0x6A Multiply the selected memory location by the value of register A and store the result in the selected memory location MUL BM [HEX] 0x6B Multiply the selected memory location by the value of register B and store the result in the selected memory location MUL CM [HEX] 0x6C Multiply the selected memory location by the value of register C and store the result in the selected memory location MUL DM [HEX] 0x6D Multiply the selected memory location by the value of register D and store the result in the selected memory location ``` ``` DIV AM [HEX] 0x7A Divide the selected memory location by the value of register A and store the result in the selected memory location DIV BM [HEX] 0x7B Divide the selected memory location by the value of register B and store the result in the selected memory location DIV CM [HEX] 0x7C Divide the selected memory location by the value of register C and store the result in the selected memory location DIV DM [HEX] 0x7D Divide the selected memory location by the value of register D and store the result in the selected memory location ``` ``` HALT 0xAA Stop the program PRN M 0xAB Print the value of the selected memory location PRN A 0xBA Print the value of register A PRN B 0xBB Print the value of register B PRN C 0xBC Print the value of register C PRN D 0xBD Print the value of register D ``` Other instructions ``` // Comment ``` ## Example Here is an example program that adds 2 numbers together and prints the result: ``` SET A 01 SEL M 00 SET M 01 ADD AM 01 HALT ``` The program is compiled to the following hex: ``` 1A010002014A01AA ``` ## Licence This project is licensed under the GPL-3.0 License - see the [LICENCE](LICENCE) file for details
