Techopedia Explains P-Code Machine

Using a variety of registers, the P-code machine handles a stack to execute the machine code according to inputs; for example, calling functions and procedures accordingly. A P-code machine can be easier to write for than a different model, however, the execution speed can be a bottleneck.

Pico may also be easier to reverse engineer than traditional code. In some ways, the idea of P-code is similar to the concept of a RISC (Reduced Instruction Set Computer) – by trimming down the footprint of the machine, certain efficiencies arise.

At the same time, key limitations apply.
