OpenPower IP Cores
The OpenPOWER Foundation is a collaboration around Power ISA-based products initiated by IBM and announced as the "OpenPOWER Consortium" on August 6, 2013. IBM is opening up technology surrounding their Power Architecture offerings, such as processor specifications, firmware and software with a liberal license, and will be using a collaborative development model with their partners. The goal is to enable the server vendor ecosystem to build their own customized server, networking and storage hardware for future data centers and cloud computing. The governing body around the Power ISA instruction set architecture, instruction set is now the OpenPOWER Foundation: IBM allows its patents to be royalty-free for Compliant implementations. Processors based on IBM's Intellectual property, IP can now be fabricated on any foundry and mixed with other hardware products of the integrator's choice. On August 20, 2019, IBM announced that the OpenPOWER Foundation would become part of the Linux ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chairperson
The chairperson, also chairman, chairwoman or chair, is the presiding officer of an organized group such as a board, committee, or deliberative assembly. The person holding the office, who is typically elected or appointed by members of the group, presides over meetings of the group, and conducts the group's business in an orderly fashion. In some organizations, the chairperson is also known as ''president'' (or other title). In others, where a board appoints a president (or other title), the two terms are used for distinct positions. Also, the chairman term may be used in a neutral manner not directly implying the gender of the holder. Terminology Terms for the office and its holder include ''chair'', ''chairperson'', ''chairman'', ''chairwoman'', ''convenor'', ''facilitator'', '' moderator'', ''president'', and ''presiding officer''. The chairperson of a parliamentary chamber is often called the ''speaker''. ''Chair'' has been used to refer to a seat or office of authority ...

POWER8
POWER8 is a family of superscalar multi-core microprocessors based on the Power ISA, announced in August 2013 at the Hot Chips conference. The designs are available for licensing under the OpenPOWER Foundation, which is the first time for such availability of IBM's highest-end processors. Systems based on POWER8 became available from IBM in June 2014. Systems and POWER8 processor designs made by other OpenPOWER members were available in early 2015. Design POWER8 is designed to be a massively multithreaded chip, with each of its cores capable of handling eight hardware threads simultaneously, for a total of 96 threads executed simultaneously on a 12-core chip. The processor makes use of very large amounts of on- and off-chip eDRAM caches, and on-chip memory controllers enable very high bandwidth to memory and system I/O. For most workloads, the chip is said to perform two to three times as fast as its predecessor, the POWER7. POWER8 chips comes in 6- or 12-core variants; e ...

Hypervisor
A hypervisor (also known as a virtual machine monitor, VMM, or virtualizer) is a type of computer software, firmware or hardware that creates and runs virtual machines. A computer on which a hypervisor runs one or more virtual machines is called a ''host machine'', and each virtual machine is called a ''guest machine''. The hypervisor presents the guest operating systems with a virtual operating platform and manages the execution of the guest operating systems. Unlike an emulator, the guest executes most instructions on the native hardware. Multiple instances of a variety of operating systems may share the virtualized hardware resources: for example, Linux, Windows, and macOS instances can all run on a single physical x86 machine. This contrasts with operating-system–level virtualization, where all instances (usually called ''containers'') must share a single kernel, though the guest operating systems can differ in user space, such as different Linux distributions with the s ...

Kernel-based Virtual Machine
Kernel-based Virtual Machine (KVM) is a virtualization module in the Linux kernel that allows the kernel to function as a hypervisor. It was merged into the mainline Linux kernel in version 2.6.20, which was released on February 5, 2007. KVM requires a processor with hardware virtualization extensions, such as Intel VT or AMD-V. KVM has also been ported to other operating systems such as FreeBSD and illumos in the form of loadable kernel modules. KVM was originally designed for x86 processors but has since been ported to S/390, PowerPC, IA-64, and ARM. KVM provides hardware-assisted virtualization for a wide variety of guest operating systems including Linux, BSD, Solaris, Windows, Haiku, ReactOS, Plan 9, AROS Research Operating System and macOS. In addition, Android 2.2, GNU/Hurd ( Debian K16), Minix 3.1.2a, Solaris 10 U3 and Darwin 8.0.1, together with other operating systems and some newer versions of these listed, are known to work with certain limitations.

Firmware
In computing, firmware is a specific class of computer software that provides the low-level control for a device's specific hardware. Firmware, such as the BIOS of a personal computer, may contain basic functions of a device, and may provide hardware abstraction services to higher-level software such as operating systems. For less complex devices, firmware may act as the device's complete operating system, performing all control, monitoring and data manipulation functions. Typical examples of devices containing firmware are embedded systems (running embedded software), home and personal-use appliances, computers, and computer peripherals. Firmware is held in non-volatile memory devices such as ROM, EPROM, EEPROM, and flash memory. Updating firmware requires ROM integrated circuits to be physically replaced, or EPROM or flash memory to be reprogrammed through a special procedure. Some firmware memory devices are permanently installed and cannot be changed after manufacture. C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Libre-SOC
Libre-SOC is a libre soft processor core originally written by Luke Leighton and other contributors, announced at the OpenPOWER Summit NA 2020. It adheres to the Power ISA 3.0 instruction set and can be run on FPGA boards, currently booting MicroPython and other bare-metal applications. The purpose of Libre-SOC is to be a system on a chip (SoC) with 3D and video capability built-in as part of the Power ISA, suitable for single-board computers, netbooks, IoT devices and other small form factors, while retaining a completely free and open design. History Libre-SOC began its life when Luke Leighton wanted there to be a completely free and libre system on a chip offering. He initially opted for a RISC-V base, but later switched to OpenPOWER when that seemed like a better fit for the project. It is the second processor written from scratch using the OpenPOWER ISA 3.0, and the first libre core that is completely independent of IBM. The project is mostly funded through N ...

Pascal (microarchitecture)
Pascal is the codename for a GPU microarchitecture developed by Nvidia, as the successor to the Maxwell architecture. The architecture was first introduced in April 2016 with the release of the Tesla P100 (GP100) on April 5, 2016, and is primarily used in the GeForce 10 series, starting with the GeForce GTX 1080 and GTX 1070 (both using the GP104 GPU), which were released on May 17, 2016 and June 10, 2016 respectively. Pascal was manufactured using TSMC's 16 nm FinFET process, and later Samsung's 14nm FinFET process. The architecture is named after the 17th century French mathematician and physicist, Blaise Pascal. In April 2019, Nvidia enabled a software implementation of DirectX Raytracing on Pascal-based cards starting with the GTX 1060 6 GB, and in the 16 series cards, a feature reserved to the Turing-based RTX series up to that point. Details In March 2014, Nvidia announced that the successor to Maxwell would be the Pascal microarchitecture; announced on May 6, 20 ...

NVLink
NVLink is a wire-based serial multi-lane near-range communications link developed by Nvidia. Unlike PCI Express, a device can consist of multiple NVLinks, and devices use mesh networking to communicate instead of a central hub. The protocol was first announced in March 2014 and uses a proprietary high-speed signaling interconnect (NVHS). Principle NVLink is a wire-based communications protocol for near-range semiconductor communications developed by Nvidia that can be used for data and control code transfers in processor systems between CPUs and GPUs and solely between GPUs. NVLink specifies a point-to-point connection with data rates of 20, 25 and 50 Gbit/s (v1.0/v2.0/v3.0 resp.) per differential pair. Eight differential pairs form a "sub-link" and two "sub-links", one for each direction, form a "link". The total data rate for a sub-link is 25 GByte/s and the total data rate for a link is 50 GByte/s. Each V100 GPU supports up to six links. Thus, each GPU is capable of supporti ...
