The PowerPC e700 or NG-64 (Next Generation 64-bit) was the codenames of the long anticipated first 64-bit

64-bit

64-bit is a word size that defines certain classes of computer architecture, buses, memory and CPUs, and by extension the software that runs on them. 64-bit CPUs have existed in supercomputers since the 1970s and in RISC-based workstations and servers since the early 1990s...

Embedded system

An embedded system is a computer system designed for specific control functions within a larger system. often with real-time computing constraints. It is embedded as part of a complete device often including hardware and mechanical parts. By contrast, a general-purpose computer, such as a personal...

 RISC-processor cores

Microprocessor

A microprocessor incorporates the functions of a computer's central processing unit on a single integrated circuit, or at most a few integrated circuits. It is a multipurpose, programmable device that accepts digital data as input, processes it according to instructions stored in its memory, and...

Power Architecture

Power Architecture is a broad term to describe similar RISC instruction sets for microprocessors developed and manufactured by such companies as IBM, Freescale, AMCC, Tundra and P.A. Semi...

 technology designed by Freescale. It was eventually revealed as the e5500 core

PowerPC e5500

The PowerPC e5500 is a 64-bit Power Architecture-based microprocessor core from Freescale Semiconductor. The core is compatible with the Power ISA v.2.06 with hypervisor support. It has a four issue, seven-stage out-of-order pipeline with a double precision FPU, three Integer units, 32/32 KB data...

.
In 2004 Freescale announced a new high performance core. Not much was known about it. It would be a multi core, multithreaded design using CoreNet technology, shared with the e500mc core. It would be a three issue core with double precision

Double precision

In computing, double precision is a computer number format that occupies two adjacent storage locations in computer memory. A double-precision number, sometimes simply called a double, may be defined to be an integer, fixed point, or floating point .Modern computers with 32-bit storage locations...

Floating point unit

A floating-point unit is a part of a computer system specially designed to carry out operations on floating point numbers. Typical operations are addition, subtraction, multiplication, division, and square root...

. Roadmaps showed a target frequency of 3+ GHz, manufactured on a 32 nm process and that the chips would be named on a MPC87xx scheme.
