ameer-virtual-processor's Introduction

Ameer Virtual Processor

This is virtual machine named Ameer Virtual Processor to which languages can be compiled to, and be ran on.

Environment

It can be ran on any python environment but for the sake of let's say performance, it should be ran with either an AOT Compiler like Nuitka or a JIT Compiler like PyPy which this virtual machine can be compiled to.

Supported type of instructions

This VM is intended to be used for dynamic languages and so it's made dynamic in it's very nature. This currently supports variables in a heap and a string heap, arrays and strings. We hope to add built in functions in this very soon and to expand on our support of arrays and strings.

Instruction Chart

What follows is a (hopefully) comprehensive description of each instruction that is currently avaliable in this virtual machine.

00 - End OF File | This instruction is used to tell the program that the file is ended before it does or for cleanliness of code.

01 - End Of Instruction | This code is used to end every instruction.

26 - GOTO_L | GOTO without popping line number from stack.

27 - IFGREAT(0) | Adds either True or False on the stack depending on if first is greater than the and second value on the stack.

28 - IFNULL(0) | Adds either True or False on the stack depending on if the first value on the stack is null.

29 - IFPLUS(0) | Adds either True or False on the stack depending on if the first value on the stack is positive.

30 - IFMINUS(0) | Adds either True or False on the stack depending on if the first value on the stack is negative.

31 - IFUNEQUAL(0) | Adds either True or False on the stack depending on if first is unequal to the second value on the stack.

32 - IFEQUAL(0) | Adds either True or False on the stack depending on if first is equal to the second value on the stack.

33 - IFSMALL(0) | Adds either True or False on the stack depending on if first is unequal to the second value on the stack.

34 - SADD | Concatenates first two elements of the stack and appends them.

35 - SCONV | Converts the first element of the stack to a string.

36 - POP_TOP | Pops the first elememnts from the stack depending on the indx you provide.

37 - GOTO_CONDITIONALLY | Conditionally GOTO a line number depending on the first value on the stack and if it's True or False.

38 - GOTO_CONDITIONALLY_L | Conditionally GOTO a line number depending on the first value on the stack and if it's True or False and don't pop conditions off the stack.

39 - LITERAL_PRINT | Print stuff with literals.

40 - NOT | Inverts the first condition on the stack.

41 - OR | OR operation on the first condition on the stack.

42 - AND | AND operation on the first condition on the stack.

43 - REGISTER | Adds first element of the stack to this register with a string name.

51 - MEMDUMP | Print entire stack.

52 - ARDISASSEMBLE | Disassemble the array on the top of the stack.

53 - ARGET | Get list's place from the top of the stack and them gets the reference from the stack. Either from the top or bottom depending on it's mode.

73 - NEGATE | Negates the first value on the top of the stack.

74 - IFSAME | Checks if two value on the top of the stack are the same value and pops them off the stack.

75 - IFSAME(0) | Checks if two value on the top of the stack are the same value and doesn't pops them off the stack.

76 - Split | Splits a string into an array by a seprator and pops it off the stack.

77 - Join | Joins an array from a string by a seprator and pops it off the stack.

Hey, btw, assembly for these instructions is already avalible here.
