  2. Stack machine - Wikipedia

    en.wikipedia.org/wiki/Stack_machine

    In a stack machine, the operands used in the instructions are always at a known offset (set in the stack pointer), from a fixed location (the bottom of the stack, which in a hardware design might always be at memory location zero), saving precious in-cache or in-CPU storage from being used to store quite so many memory addresses or index ...

  3. Instruction set architecture - Wikipedia

    en.wikipedia.org/wiki/Instruction_set_architecture

    (In the examples that follow, a, b, and c are (direct or calculated) addresses referring to memory cells, while reg1 and so on refer to machine registers.) C = A+B 0-operand (zero-address machines), so called stack machines: All arithmetic operations take place using the top one or two positions on the stack: [9] push a, push b, add, pop c.

  4. Machine code - Wikipedia

    en.wikipedia.org/wiki/Machine_code

    Machine code is generally different from bytecode (also known as p-code), which is either executed by an interpreter or itself compiled into machine code for faster (direct) execution. An exception is when a processor is designed to use a particular bytecode directly as its machine code, such as is the case with Java processors .

  5. B5000 instruction set - Wikipedia

    en.wikipedia.org/wiki/B5000_Instruction_Set

    The Burroughs B5000 was the first stack machine and also the first computer with a segmented virtual memory. The Burroughs B5000 instruction set includes the set of valid operations for the B5000, B5500 and B5700. It is not compatible with the B6500, B7500, B8500 or their successors.

  6. Call stack - Wikipedia

    en.wikipedia.org/wiki/Call_stack

    This type of stack is also known as an execution stack, program stack, control stack, run-time stack, or machine stack, and is often shortened to simply the "stack". Although maintenance of the call stack is important for the proper functioning of most software , the details are normally hidden and automatic in high-level programming languages .

  7. x86 assembly language - Wikipedia

    en.wikipedia.org/wiki/X86_assembly_language

    SS:SP (SS is Stack Segment, SP is Stack Pointer) points to the address of the top of the stack, i.e. the most recently pushed byte. SS:BP (SS is Stack Segment, BP is Stack Frame Pointer) points to the address of the top of the stack frame, i.e. the base of the data area in the call stack for the currently active subprogram.

  8. Addressing mode - Wikipedia

    en.wikipedia.org/wiki/Addressing_mode

    Such accumulator machines implicitly reference that accumulator in almost every instruction. For example, the operation < a := b + c; > can be done using the sequence < load b; add c; store a; > -- the destination (the accumulator) is implied in every "load" and "add" instruction; the source (the accumulator) is implied in every "store ...

  9. Stack-oriented programming - Wikipedia

    en.wikipedia.org/wiki/Stack-oriented_programming

    The simple model provided in a stack-oriented language allows expressions and programs to be interpreted simply and theoretically evaluated much faster, since no syntax analysis needs to be done but lexical analysis. The way such programs are written facilitates being interpreted by machines, which is why PostScript suits printers well for its use.
