Pascal Implementation: P4 Compiler Compiler And... -

By targeting an abstract "P-Machine," the compiler remains machine-independent. To port Pascal to a new system, one only needs to write a P-Code interpreter or a P-Code-to-native-code translator for that specific hardware.

Also written in Pascal, it acts as a virtual machine that assembles and executes the P-Code output. Implementation and Bootstrapping Process PASCAL Implementation: P4 Compiler Compiler and...

The compiler is the fourth iteration of the Pascal-P system developed at ETH Zurich. It is a portable "compiler-compiler" implementation kit designed to aid in the bootstrapping of Pascal compilers on new machine architectures by producing an intermediate code known as P-Code . Core Components of the P4 System The system typically consists of two main programs: By targeting an abstract "P-Machine," the compiler remains
