What (who) is P- code - definition

PROGRAMMING VIRTUAL MACHINE

Microsoft P-Code; P-Code machine; Pseudo-code machine; Portable code machine; Packed code (Microsoft P-Code); Pseudo code (Microsoft P-Code); UCSD p-code

P-code

FORM OF INSTRUCTION SET DESIGNED TO BE RUN BY A SOFTWARE INTERPRETER

Byte code; P-Code; P-Codes; Intermediate code; Byte-code; Bitcode; Byte Code; Bytecodes; Portable code; P-code; Byte-compile; Byte-compiler; Byte-code compiler

<language> The intermediate language produced by the Pascal-P compiler. P-code is the assembly language for a hypothetical stack machine, the P-machine, said to imitate the instruction set of the Burroughs 6700. The term was first used in the Wirth reference below. Byte articles on writing a Pascal Compiler in Northstar BASIC (ca Aug 1978) also used the term. P-code was initially the intermediate code generated by the P2 compiler from ETH Zurich. P-code was later used as the intermediate language in the UCSD Pascal System, and in its two main derivatives, Apple Pascal and the UCSD P-system. Variants: P2 P-code, P4 P-code, UCSD P-code, LASL P-code. [Algorithms + Data Structures = Programs, N. Wirth, P-H 1976]. ["A Comparison of PASCAL Intermediate Languages", P.A. Nelson, SIGPLAN Notices 14(8):208-213, Aug 1979]. (2004-11-08)

P-Code (disambiguation)

WIKIMEDIA DISAMBIGUATION PAGE

P-code (disambiguation)

P-code is an alternative term for bytecode, machine-independent code that achieves independence by targeting a p-code machine, a virtual machine designed for running p-code rather than the intention to emulate any specific hardware architecture.

P-code machine

In computer programming, a p-code machine (portable code machine) is a virtual machine designed to execute p-code (the assembly language or machine code of a hypothetical central processing unit (CPU)). This term is applied both generically to all such machines (such as the Java virtual machine (JVM) and MATLAB precompiled code), and to specific implementations, the most famous being the p-Machine of the Pascal-P system, particularly the UCSD Pascal implementation, among whose developers, the p in p-code was construed to mean pseudo more often than portable, thus pseudo-code meaning instructions for a pseudo-machine.

P-code machine

In computer programming, a p-code machine (portable code machine) is a virtual machine designed to execute p-code (the assembly language or machine code of a hypothetical central processing unit (CPU)). This term is applied both generically to all such machines (such as the Java virtual machine (JVM) and MATLAB precompiled code), and to specific implementations, the most famous being the p-Machine of the Pascal-P system, particularly the UCSD Pascal implementation, among whose developers, the p in p-code was construed to mean pseudo more often than portable, thus pseudo-code meaning instructions for a pseudo-machine.

Although the concept was first implemented circa 1966—as O-code for the Basic Combined Programming Language (BCPL) and P code for the language Euler—the term p-code first appeared in the early 1970s. Two early compilers generating p-code were the Pascal-P compiler in 1973, by Kesav V. Nori, Urs Ammann, Kathleen Jensen, Hans-Heinrich Nägeli, and Christian Jacobi, and the Pascal-S compiler in 1975, by Niklaus Wirth.

Programs that have been translated to p-code can either be interpreted by a software program that emulates the behavior of the hypothetical CPU, or translated into the machine code of the CPU on which the program is to run and then executed. If there is sufficient commercial interest, a hardware implementation of the CPU specification may be built (e.g., the Pascal MicroEngine or a version of a Java processor).
