P3 CPU Introduction
The P3 is a 16-bit CPU used at Instituto Superior Técnico (IST) as a learning tool for Computer Engineering students.
It is described in chapters 10, 11 and 12 of the book:
Arquitectura de Computadores: Dos Sistemas Digitais aos Microprocessadores
G. Arroz, J. Monteiro, A. Oliveira
Some official links (in Portuguese):
The P3 itself is not a commercial product and doesn’t exist as a dedicated IC. It is normally implemented on an FPGA or simulated on a computer.
Not to be confused with the Pentium III.
