A virtual machine (VM) known as the P-machine (PM/0). The P-machine is a stack machine with two memory stores: the “stack,” which is organized as a stack and contains the data to be used by the PM/0 CPU, and the “code,” which is organized as a list and contains the instructions for the VM. The PM/0 CPU has four registers to handle the stack and code segments: The registers are named base pointer (BP), stack pointer (SP), program counter (PC) and instruction register (IR). They will be explained in detail later on in this document. The machine also has a register file (RF) with sixteen (16) registers (0-15).
