Tensilica Instruction Extension
Tensilica Instruction Extension refers to the proprietary language that is used to customize Tensilica's Xtensa processor core architecture. By using TIE, the user can customize the Xtensa architecture by adding custom instructions and register files, instantiating TIE Ports and Queues for multiprocessor communication, and adding pre-configured extensions (such as Tensilica's DSP). Software applications can greatly benefit from properly targeted user-defined instructions, while TIE ports and TIE queues facilitate multiprocessor communication by adding separate input and output interfaces to the processor core. Using the TIE language and Xtensa Xplorer toolkit, the generation and verification of the instructions used to extend the processor ISA are automated. Such automation helps to reduce the hardware verification time that typically consumes a large percentage of the project duration of a typical hardware developed for the same functionality. History TIE was added by Tensilic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tensilica
Tensilica was a company based in Silicon Valley in the semiconductor intellectual property core business. It is now a part of Cadence Design Systems. Tensilica is known for its customizable Xtensa microprocessor core. Other products include: HiFi audio/voice DSPs (digital signal processors) with a software library of over 225 codecs from Cadence and over 100 software partners; Vision DSPs that handle complex algorithms in imaging, video, computer vision, and neural networks; and the ConnX family of baseband DSPs ranging from the dual- MAC ConnX D2 to the 64-MAC ConnX BBE64EP. Tensilica was founded in 1997 by Chris Rowen (one of the founders of MIPS Technologies). It employed Earl Killian, who contributed to the MIPS architecture, as director of architecture. On March 11, 2013, Cadence Design Systems announced its intent to buy Tensilica for approximately $380 million in cash. Cadence completed the acquisition in April 2013, with a cash outlay at closing of approximately $326 mill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Computer Programming
Computer programming is the process of performing a particular computation (or more generally, accomplishing a specific computing result), usually by designing and building an executable computer program. Programming involves tasks such as analysis, generating algorithms, profiling algorithms' accuracy and resource consumption, and the implementation of algorithms (usually in a chosen programming language, commonly referred to as coding). The source code of a program is written in one or more languages that are intelligible to programmers, rather than machine code, which is directly executed by the central processing unit. The purpose of programming is to find a sequence of instructions that will automate the performance of a task (which can be as complex as an operating system) on a computer, often for solving a given problem. Proficient programming thus usually requires expertise in several different subjects, including knowledge of the application domain, specialized algori ...

Verilog
Verilog, standardized as IEEE 1364, is a hardware description language (HDL) used to model electronic systems. It is most commonly used in the design and verification of digital circuits at the register-transfer level of abstraction. It is also used in the verification of analog circuits and mixed-signal circuits, as well as in the design of genetic circuits. In 2009, the Verilog standard (IEEE 1364-2005) was merged into the SystemVerilog standard, creating IEEE Standard 1800-2009. Since then, Verilog is officially part of the SystemVerilog language. The current version is IEEE standard 1800-2017. Overview Hardware description languages such as Verilog are similar to software programming languages because they include ways of describing the propagation time and signal strengths (sensitivity). There are two types of assignment operators; a blocking assignment (=), and a non-blocking (>>. A generate–endgenerate construct (similar to VHDL's generate–endgenerate) allows Verilog ...

Hardware Description Language
In computer engineering, a hardware description language (HDL) is a specialized computer language used to describe the structure and behavior of electronic circuits, and most commonly, digital logic circuits. A hardware description language enables a precise, formal description of an electronic circuit that allows for the automated analysis and simulation of an electronic circuit. It also allows for the synthesis of an HDL description into a netlist (a specification of physical electronic components and how they are connected together), which can then be placed and routed to produce the set of masks used to create an integrated circuit. A hardware description language looks much like a programming language such as C or ALGOL; it is a textual description consisting of expressions, statements and control structures. One important difference between most programming languages and HDLs is that HDLs explicitly include the notion of time. HDLs form an integral part of electr ...

Electronic Design Automation
Electronic design automation (EDA), also referred to as electronic computer-aided design (ECAD), is a category of software tools for designing Electronics, electronic systems such as integrated circuits and printed circuit boards. The tools work together in a Design flow (EDA), design flow that chip designers use to design and analyze entire semiconductor chips. Since a modern semiconductor chip can have billions of components, EDA tools are essential for their design; this article in particular describes EDA specifically with respect to integrated circuits (ICs). History Early days Prior to the development of EDA, integrated circuits were designed by hand and manually laid out. Some advanced shops used geometric software to generate tapes for a Gerber format, Gerber photoplotter, responsible for generating a monochromatic exposure image, but even those copied digital recordings of mechanically drawn components. The process was fundamentally graphic, with the translation f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vim (text Editor)
Vim (; "Vim is pronounced as one word, like Jim, not vi-ai-em. It's written with a capital, since it's a name, again like Jim." a contraction of ''Vi IMproved'') is a free and open-source, program. It is an improved clone of 's vi. Vim's author, Bram Moolenaar, derived Vim from a port of the [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
