Processor design is a subfield of computer engineering and electronics engineering (fabrication) that deals with creating a processor, a key component of computer hardware.
Very long instruction word (VLIW) refers to instruction set architectures designed to exploit instruction level parallelism (ILP). Whereas conventional central processing units mostly allow programs to specify instructions to execute in sequence only, a VLIW processor allows programs to explicitly specify instructions to execute in parallel. This design is intended to allow higher performance without the complexity inherent in some other designs.
The Motorola DSP56000 is a family of digital signal processor (DSP) chips produced by Motorola Semiconductor starting in 1986 with later models are still being produced in the 2020s. The 56k series was quite popular for a time in a number of computers, including the NeXT, Atari Falcon030 and SGI Indigo workstations all using the 56001. Upgraded 56k versions are still used today in audio equipment, radar systems, communications devices and various other embedded DSP applications. The 56000 was also used as the basis for the updated 96000, which was not commercially successful.
XScale is a microarchitecture for central processing units initially designed by Intel implementing the ARM architecture instruction set. XScale comprises several distinct families: IXP, IXC, IOP, PXA and CE, with some later models designed as system-on-a-chip (SoC). Intel sold the PXA family to Marvell Technology Group in June 2006. Marvell then extended the brand to include processors with other microarchitectures, like ARM's Cortex.
A digital signal processor (DSP) is a specialized microprocessor chip, with its architecture optimized for the operational needs of digital signal processing. DSPs are fabricated on MOS integrated circuit chips. They are widely used in audio signal processing, telecommunications, digital image processing, radar, sonar and speech recognition systems, and in common consumer electronic devices such as mobile phones, disk drives and high-definition television (HDTV) products.
Transmeta Corporation was an American fabless semiconductor company based in Santa Clara, California. It developed low power x86 compatible microprocessors based on a VLIW core and a software layer called Code Morphing Software.
In computing, a benchmark is the act of running a computer program, a set of programs, or other operations, in order to assess the relative performance of an object, normally by running a number of standard tests and trials against it.
The Fujitsu FR-V is one of the very few processors ever able to process both a very long instruction word (VLIW) and vector processor instructions at the same time, increasing throughput with high parallel computing while increasing performance per watt and hardware efficiency. The family was presented in 1999. Its design was influenced by the VPP500/5000 models of the Fujitsu VP/2000 vector processor supercomputer line.
A multi-core processor is a microprocessor on a single integrated circuit with two or more separate processing units, called cores, each of which reads and executes program instructions. The instructions are ordinary CPU instructions but the single processor can run instructions on separate cores at the same time, increasing overall speed for programs that support multithreading or other parallel computing techniques. Manufacturers typically integrate the cores onto a single integrated circuit die or onto multiple dies in a single chip package. The microprocessors currently used in almost all personal computers are multi-core.
A media processor, mostly used as an image/video processor, is a microprocessor-based system-on-a-chip which is designed to deal with digital streaming data in real-time rates. These devices can also be considered a class of digital signal processors (DSPs).
ARM9 is a group of 32-bit RISC ARM processor cores licensed by ARM Holdings for microcontroller use. The ARM9 core family consists of ARM9TDMI, ARM940T, ARM9E-S, ARM966E-S, ARM920T, ARM922T, ARM946E-S, ARM9EJ-S, ARM926EJ-S, ARM968E-S, ARM996HS. Since ARM9 cores were released from 1998 to 2006, they are no longer recommended for new IC designs, instead ARM Cortex-A, ARM Cortex-M, ARM Cortex-R cores are preferred.
TRIPS was a microprocessor architecture designed by a team at the University of Texas at Austin in conjunction with IBM, Intel, and Sun Microsystems. TRIPS uses an instruction set architecture designed to be easily broken down into large groups of instructions (Graphs) that can be run on independent processing elements. The design collects related data into the graphs, attempting to avoid expensive data reads and writes and keeping the data in high speed memory close to the processing elements. The prototype TRIPS processor contains 16 such elements. TRIPS hoped to reach 1 TFLOP on a single processor, as papers were published from 2003 to 2006.
The i.MX range is a family of Freescale Semiconductor proprietary microcontrollers for multimedia applications based on the ARM architecture and focused on low-power consumption. The i.MX application processors are SoCs (System-on-Chip) that integrate many processing units into one die, like the main CPU, a video processing unit and a graphics processing unit for instance. The i.MX products are qualified for automotive, industrial and consumer markets. Most of them are guaranteed for a production lifetime of 10 to 15 years.
Many devices use i.MX processors, such as Ford Sync, Kobo eReader, Amazon Kindle, Zune, Sony Reader, Onyx Boox readers/tablets, SolidRun SOM's, Purism's Librem 5, some Logitech Harmony remote controls and Squeezebox radio, some Toshiba Gigabeat mp4 players. The i.MX range was previously known as the "DragonBall MX" family, the fifth generation of DragonBall microcontrollers. i.MX originally stood for "innovative Multimedia eXtension".
QorIQ is a brand of ARM-based and Power ISA–based communications microprocessors from NXP Semiconductors. It is the evolutionary step from the PowerQUICC platform, and initial products were built around one or more e500mc cores and came in five different product platforms, P1, P2, P3, P4, and P5, segmented by performance and functionality. The platform keeps software compatibility with older PowerPC products such as the PowerQUICC platform. In 2012 Freescale announced ARM-based QorIQ offerings beginning in 2013.
The ARM Cortex-A9 MPCore is a 32-bit multi-core processor that provides up to 4 cache-coherent cores, each implementing the ARM v7 architecture instruction set. It was introduced in 2007.
Ne-XVP was a research project executed between 2006-2008 at NXP Semiconductors. The project undertook a holistic approach to define a next generation multimedia processing architecture for embedded MPSoCs that targets programmability, performance scalability, and silicon efficiency in an evolutionary way. The evolutionary way implies using existing processor cores such as NXP TriMedia as building blocks and supporting industry programming standards such as POSIX threads. Based on the technology-aware design space exploration, the project concluded that hardware accelerators facilitating task management and coherency coupled with right dimensioning of compute cores deliver good programmability, scalable performance and competitive silicon efficiency.
The PowerPC e6500 is a multithreaded 64-bit Power ISA-based microprocessor core from Freescale Semiconductor. e6500 will power the entire range of QorIQ AMP Series system on a chip (SoC) processors which share the common naming scheme: "Txxxx". Hard samples, manufactured on a 28 nm process, available in early 2012 with full production later in 2012.
LPC is a family of 32-bit microcontroller integrated circuits by NXP Semiconductors. The LPC chips are grouped into related series that are based around the same 32-bit ARM processor core, such as the Cortex-M4F, Cortex-M3, Cortex-M0+, or Cortex-M0. Internally, each microcontroller consists of the processor core, static RAM memory, flash memory, debugging interface, and various peripherals. The earliest LPC series were based on the Intel 8-bit 80C51 core. As of February 2011, NXP had shipped over one billion ARM processor-based chips.
Nexperia was the NXP Semiconductors brand for a family of processors, primarily featuring Media Processor system-on-chip (SoC) and media co-processors, but also briefly including highly-integrated mobile (SoC) products.
