4.2.1 e500 Processor Core
The e500v2 (P2020)QorIQ integrated processor offers high performance dual core. It operates
from 1.0GHz up to 1.2GHz core frequency. The e500 processor core is a low-power
implementation of the family of reduced instruction set computing (RISC) embedded
processor that implement the Book E definition of the PowerPC architecture. The e500 is a 32-
bit implementation of the Book E architecture using the lower words of 64-bit general-purpose
registers (GPRs) while E500v2 uses 36 bit physical addressing.
