PowerPC E700
The PowerPC e700 or NG-64 (Next Generation 64-bit) were the codenames of Freescale's first 64-bit embedded RISC- processor cores. 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 FPU. 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. Freescale released a core with similar specifications in June 2010 called the e5500.

Freescale
Freescale Semiconductor, Inc. was an American semiconductor manufacturer. It was created by the divestiture of the Semiconductor Products Sector of Motorola in 2004. Freescale focused their integrated circuit products on the automotive, embedded and communications markets. It was bought by a private investor group in 2006, and subsequently merged into NXP Semiconductors in 2015. History As of 2003, Motorola Semiconductor Products Sector earned US$5.0 billion in semiconductor sales in 2002 (out of US$27 billion sales for all of Motorola). Motorola announced that their semiconductor division would be divested on October 6, 2003, to create Freescale. Freescale completed its Initial public offering (IPO) on July 16, 2004, at a price of US$13. In its announcement, it estimated the stock price to be US$17.50- 19.50 but following a cooling of the market towards tech stocks, it lowered its price to US$13. Existing shareholders of Motorola stock received 0.110415 shares of Freescale ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
64-bit
In computer architecture, 64-bit Integer (computer science), integers, memory addresses, or other Data (computing), data units are those that are 64 bits wide. Also, 64-bit central processing unit, CPUs and arithmetic logic unit, ALUs are those that are based on processor registers, address buses, or Bus (computing), data buses of that size. A computer that uses such a processor is a 64-bit computer. From the software perspective, 64-bit computing means the use of machine code with 64-bit virtual memory addresses. However, not all 64-bit instruction sets support full 64-bit virtual memory addresses; x86-64 and ARMv8, for example, support only 48 bits of virtual address, with the remaining 16 bits of the virtual address required to be all 0's or all 1's, and several 64-bit instruction sets support fewer than 64 bits of physical memory address. The term ''64-bit'' also describes a generation of computers in which 64-bit processors are the norm. 64 bits is a Word (computer archit ...

Embedded System
An embedded system is a computer system—a combination of a computer processor, computer memory, and input/output peripheral devices—that has a dedicated function within a larger mechanical or electronic system. It is ''embedded'' as part of a complete device often including electrical or electronic hardware and mechanical parts. Because an embedded system typically controls physical operations of the machine that it is embedded within, it often has real-time computing constraints. Embedded systems control many devices in common use today. , it was estimated that ninety-eight percent of all microprocessors manufactured were used in embedded systems. Modern embedded systems are often based on microcontrollers (i.e. microprocessors with integrated memory and peripheral interfaces), but ordinary microprocessors (using external chips for memory and peripheral interface circuits) are also common, especially in more complex systems. In either case, the processor(s) used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RISC
In computer engineering, a reduced instruction set computer (RISC) is a computer designed to simplify the individual instructions given to the computer to accomplish tasks. Compared to the instructions given to a complex instruction set computer (CISC), a RISC computer might require more instructions (more code) in order to accomplish a task because the individual instructions are written in simpler code. The goal is to offset the need to process more instructions by increasing the speed of each instruction, in particular by implementing an instruction pipeline, which may be simpler given simpler instructions. The key operational concept of the RISC computer is that each instruction performs only one function (e.g. copy a value from memory to a register). The RISC computer usually has many (16 or 32) high-speed, general-purpose registers with a load/store architecture in which the code for the register-register instructions (for performing arithmetic and tests) are separate fr ...

Microprocessor
A microprocessor is a computer processor where the data processing logic and control is included on a single integrated circuit, or a small number of integrated circuits. The microprocessor contains the arithmetic, logic, and control circuitry required to perform the functions of a computer's central processing unit. The integrated circuit is capable of interpreting and executing program instructions and performing arithmetic operations. The microprocessor is a multipurpose, clock-driven, register-based, digital integrated circuit that accepts binary data as input, processes it according to instructions stored in its memory, and provides results (also in binary form) as output. Microprocessors contain both combinational logic and sequential digital logic, and operate on numbers and symbols represented in the binary number system. The integration of a whole CPU onto a single or a few integrated circuits using Very-Large-Scale Integration (VLSI) greatly reduced the cost of ...

Double Precision
Double-precision floating-point format (sometimes called FP64 or float64) is a floating-point number format, usually occupying 64 bits in computer memory; it represents a wide dynamic range of numeric values by using a floating radix point. Floating point is used to represent fractional values, or when a wider range is needed than is provided by fixed point (of the same bit width), even if at the cost of precision. Double precision may be chosen when the range or precision of single precision would be insufficient. In the IEEE 754-2008 standard, the 64-bit base-2 format is officially referred to as binary64; it was called double in IEEE 754-1985. IEEE 754 specifies additional floating-point formats, including 32-bit base-2 ''single precision'' and, more recently, base-10 representations. One of the first programming languages to provide single- and double-precision floating-point data types was Fortran. Before the widespread adoption of IEEE 754-1985, the representation and p ...

32 Nm
The 32 nm node is the step following the 45 nm process in CMOS (MOSFET) semiconductor device fabrication. "32-nanometre" refers to the average half-pitch (i.e., half the distance between identical features) of a memory cell (computing), memory cell at this technology level. Toshiba produced commercial 32Gibibit, GiB NAND flash memory chips with the 32nm process in 2009. Intel Corporation, Intel and Advanced Micro Devices, AMD produced commercial microchips using the 32-nanometre process in the early 2010s. IBM and the Common Platform also developed a 32 nm high-κ dielectric, high-κ metal gate process. Intel began selling its first 32 nm processors using the Westmere (microarchitecture), Westmere architecture on 7 January 2010. The 28-nanometre node was an intermediate half-node die shrink based on the 32-nanometre process. The 32 nm process was superseded by commercial 22 nm process, 22 nm technology in 2012.

Motorola G5 Project
The Motorola G5 project was an unsuccessful attempt around 2000-2001 to create a 64-bit PowerPC processor, as a successor to Motorola's PowerPC G4, PowerPC 7400 series. On roadmaps from the era it was designated PowerPC 7500. It has been suggested that Motorola had a working "G5" chip, but said chip failed in the early stages of mass production and thus could not be widely made into a usable chip. When Apple began producing 64-bit systems under the G5 brand, they used IBM's PowerPC 970, which is also known as the PowerPC G5.

PowerPC Microprocessors
PowerPC (with the backronym Performance Optimization With Enhanced RISC – Performance Computing, sometimes abbreviated as PPC) is a reduced instruction set computer (RISC) instruction set architecture (ISA) created by the 1991 Apple– IBM–Motorola alliance, known as AIM. PowerPC, as an evolving instruction set, has been named Power ISA since 2006, while the old name lives on as a trademark for some implementations of Power Architecture–based processors. PowerPC was the cornerstone of AIM's PReP and Common Hardware Reference Platform (CHRP) initiatives in the 1990s. Originally intended for personal computers, the architecture is well known for being used by Apple's Power Macintosh, PowerBook, iMac, iBook, eMac, Mac Mini, and Xserve lines from 1994 until 2005, when Apple migrated to Intel's x86. It has since become a niche in personal computers, but remains popular for embedded and high-performance processors. Its use in 7th generation of video game consoles and embedde ...
