Tilera
Tilera Corporation was a fabless semiconductor company focusing on manycore embedded processor design. The company shipped multiple processors in the TILE64, TILE''Pro''64, and TILE-Gx lines. After a series of company acquisitions, Tilera's intellectual property was eventually acquired by Nvidia (via EZChip, then Mellanox), which now ships '' BlueField'' products that descend from the Tilera designs. History In 1990, Anant Agarwal led a team of researchers at Massachusetts Institute of Technology to develop scalable multi-processor system built out of large numbers of single chip processors. Alewife machines integrated both shared memory and user-level message passing for inter-node communications. In 1997, Agarwal proposed a follow-on project using a mesh technology to connect multiple cores. The follow-on project, named RAW, commenced in 1997, and was supported by DARPA/NSF's funding of tens of millions, resulting in the first 16-processor tiles multicore and proving t ...

TILEPro64
TILE''Pro''64 is a VLIW ISA multicore processor ( Tile processor) manufactured by Tilera. It consists of a cache-coherent mesh network of 64 "tiles", where each tile houses a general purpose processor, cache, and a non-blocking router, which the tile uses to communicate with the other tiles on the processor. The short-pipeline, in-order, three-issue cores implement a VLIW instruction set. Each core has a register file and three functional units: two integer arithmetic logic units and a load–store unit. Each of the cores ("tile") has its own L1 and L2 caches plus an overall virtual L3 cache which is an aggregate of all the L2 caches. A core is able to run a full operating system on its own or multiple cores can be used to run a symmetrical multi-processing operating system. TILE''Pro''64 has four DDR2 controllers at up to 800MT/s, two 10-gigabit Ethernet XAUI interfaces, two four-lane PCIe interfaces, and a "flexible" input/output interface, which can be software-configure ...

TILE64 is a VLIW ISA multicore processor manufactured by Tilera. It consists of a mesh network of 64 "tiles", where each tile houses a general purpose processor, cache, and a non-blocking router, which the tile uses to communicate with the other tiles on the processor. The short-pipeline, in-order, three-issue cores implement a MIPS-inspired VLIW instruction set. Each core has a register file and three functional units: two integer arithmetic logic units and a load–store unit.

TILE-Gx
TILE-Gx was a VLIW ISA multicore processor family designed by Tilera. It consisted of a mesh network that was expected to scale up to 100 cores, but only 72-core variants actually shipped. After a few acquisitions, Tilera's designs ended up in the hands of Nvidia, which ended production of TILE-Gx processors in 2022. In June 2018, the Linux kernel dropped support for this architecture. Tile-Gx processors were used in MikroTik's CCR1000 series routers, and MikroTik continues to support this architecture out-of-tree in its RouterOS Linux distribution. Product lineup Common features of TILE-Gx processors: * 64-bit VLIW RISC core (3-issue) * 4 MAC/cycle with SIMD extensions * L1 cache: 64 KB (32 KB data + 32 KB instruction) per core. * L2 cache: 256 KB per core. * L3 cache: Other core's L2 cache connected via mesh network. * 1, 2, or 4 ECC 72-bit DDR3 controllers. * Up to 24 PCIe 2.0 lanes. * Optional built-in crypto accelerator with 40 Gbit/s encry ...

EZchip Semiconductor
EZchip Semiconductor Ltd. was a publicly traded fabless semiconductor company, headquartered in Yokneam, Israel, that developed and marketed Ethernet network processors. It was acquired by Mellanox Technologies in 2016. History EZchip was co-founded in 1999 by Eli Fruchter, a Technion graduate in the field of electrical engineering and veteran of the Israel Defense Forces' 8200 intelligence unit, and Alex Tal who served as Ezchip's first CTO and V.P R&D. Until 2008, EZchip operated as a subsidiary of LANOptics, then a developer of Ethernet switching chips and security software. After LANOptics completed its full acquisition of EZchip in January 2008, it changed its name to EZchip and its ticker symbol from LNOP to EZCH.

Manycore Processor
Manycore processors are special kinds of multi-core processors designed for a high degree of parallel processing, containing numerous simpler, independent processor cores (from a few tens of cores to thousands or more). Manycore processors are used extensively in embedded computers and high-performance computing. Contrast with multicore architecture Manycore processors are distinct from multi-core processors in being optimized from the outset for a higher degree of explicit parallelism, and for higher throughput (or lower power consumption) at the expense of latency and lower single-thread performance. The broader category of multi-core processors, by contrast, are usually designed to efficiently run ''both'' parallel ''and'' serial code, and therefore place more emphasis on high single-thread performance (e.g. devoting more silicon to out-of-order execution, deeper pipelines, more superscalar execution units, and larger, more general caches), and shared memory.

Cloud Computing
Cloud computing is "a paradigm for enabling network access to a scalable and elastic pool of shareable physical or virtual resources with self-service provisioning and administration on-demand," according to International Organization for Standardization, ISO. Essential characteristics In 2011, the National Institute of Standards and Technology (NIST) identified five "essential characteristics" for cloud systems. Below are the exact definitions according to NIST: * On-demand self-service: "A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service provider." * Broad network access: "Capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, tablets, laptops, and workstations)." * Pooling (resource management), Resource pooling: " The provider' ...

Web Indexing
Web indexing, or Internet indexing, comprises methods for indexing the contents of a website or of the Internet as a whole. Individual websites or intranets may use a back-of-the-book index, while search engines usually use keywords and Metadata (computing), metadata to provide a more useful vocabulary for Internet or onsite searching. With the increase in the number of periodicals that have articles online, web indexing is also becoming important for periodical websites. Back-of-the-book-style web indexes may be called "web site A-Z indexes". The implication with "A-Z" is that there is an alphabetical browse view or interface. This interface differs from that of a browse through layers of hierarchical categories (also known as a Taxonomy (general), taxonomy) which are not necessarily alphabetical, but are also found on some web sites. Although an A-Z index could be used to index multiple sites, rather than the multiple pages of a single site, this is unusual. Metadata web indexin ...

Walden International
Pacven Walden Management Co., Ltd. (doing business as Walden International) is an American venture capital firm based in San Francisco, California. It mainly focuses on investments in Asia and is one of the earliest venture capital firms to invest in the region. The firm is known for playing a significant role in helping China's technology development. History The origins of Walden International can be traced back to Walden Group (now known as Walden Venture Capital), one of the earliest San Francisco venture capital firms that was founded in 1974 by Art Berliner and George Sarlo. The firm's name comes from the book ''Walden'' by Henry David Thoreau which espoused challenging the status quo. In 1983, when the U.S. venture capital market got overheated, the firm began exploring how to export the venture capital model overseas. During that year it hired Lip-Bu Tan to open up business in the Asian Market. Shortly after, Tan became an senior partner at the firm. In 1987, in re ...
