SpecC
SpecC is a System Description Language (SDL), or System-level Design Language (SLDL), and is an extension of the ANSI C programming language. It is used to aid the design and specification of digital embedded systems, providing improved productivity whilst retaining the ability to change a design at functional and specification level, unlike HDLs like Verilog and VHDL. An architectural model can be created which allows other tools to directly map the design onto silicon or FPGA. The main aim is for the reuse, exchange and integration of IP at various levels of abstraction. The language and design methodology were created by Rainer Dömer and Daniel Gajski at the Centre for Embedded Computer Systems at University of California, Irvine in 2001. Similar projects and design methodologies include SystemC, an SDL based on C++. Although this rival language has seen much more widespread industry usage (although SpecC is popular in Japan), SpecC retains simplicity whilst also providing ...

Daniel Gajski
Daniel Gajski is a Professor of the School of Information and Computer Science and the School of Engineering at University of California, Irvine, United States. He was previously the Director for the Center for Embedded Computer Systems (CECS), now known as the Center for Embedded and Cyber-physical Systems. After 10 years of industrial experience in Europe and the United States in digital circuits, telecommunication systems, supercomputer design, and VLSI structures, he spent 10 years in academia with the Department of Computer Science at the University of Illinois at Urbana-Champaign.

SystemVerilog
SystemVerilog, standardized as IEEE 1800, is a hardware description and hardware verification language used to model, design, simulate, test and implement electronic systems. SystemVerilog is based on Verilog and some extensions, and since 2008 Verilog is now part of the same IEEE standard. It is commonly used in the semiconductor and electronic design industry as an evolution of Verilog. History SystemVerilog started with the donation of the Superlog language to Accellera in 2002 by the startup company Co-Design Automation. The bulk of the verification functionality is based on the OpenVera language donated by Synopsys. In 2005, SystemVerilog was adopted as IEEE Standard 1800-2005. In 2009, the standard was merged with the base Verilog (IEEE 1364-2005) standard, creating IEEE Standard 1800-2009. The current version is IEEE standard 1800-2017. The feature-set of SystemVerilog can be divided into two distinct roles: # SystemVerilog for register-transfer level (RTL) design is a ...

University Of California, Irvine
The University of California, Irvine (UCI or UC Irvine) is a public land-grant research university in Irvine, California. One of the ten campuses of the University of California system, UCI offers 87 undergraduate degrees and 129 graduate and professional degrees, and roughly 30,000 undergraduates and 6,000 graduate students are enrolled at UCI as of Fall 2019. The university is classified among " R1: Doctoral Universities – Very high research activity", and had $436.6 million in research and development expenditures in 2018. UCI became a member of the Association of American Universities in 1996. The university was rated as one of the "Public Ivies” in 1985 and 2001 surveys comparing publicly funded universities the authors claimed provide an education comparable to the Ivy League. The university also administers the UC Irvine Medical Center, a large teaching hospital in Orange, and its affiliated health sciences system; the University of California, Irvine, Arboretum; and ...

Accellera
Accellera Systems Initiative (Accellera) is a standards organization that supports a mix of user and vendor standards and open interfaces development in the area of electronic design automation (EDA) and integrated circuit (IC) design and manufacturing. It is less constrained than the Institute of Electrical and Electronics Engineers (IEEE) and is therefore the starting place for many standards. Once mature and adopted by the broader community, the standards are usually transferred to the IEEE. History In 2000, Accellera was founded from the merger of Open Verilog International (OVI) and VHDL International, the developers of Verilog and VHDL respectively. Both were originally formed nine years earlier in 1991. In June 2009, a merger was announced between Accellera and The SPIRIT Consortium, another major EDA standards organization focused on IP deployment and reuse. The SPIRIT Consortium obtained SystemRDL from the SystemRDL Alliance and then developed IP-XACT. The merger was com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Composite Data Type
In computer science, a composite data type or compound data type is any data type which can be constructed in a program using the programming language's primitive data types and other composite types. It is sometimes called a structure or aggregate data type, although the latter term may also refer to arrays, lists, etc. The act of constructing a composite type is known as composition. Composite data types are often contrasted with scalar variables. C/C++ structures and classes A struct is C's and C++'s notion of a composite type, a datatype that composes a fixed set of labeled fields or members. It is so called because of the struct keyword used in declaring them, which is short for ''structure'' or, more precisely, ''user-defined data structure''. In C++, the only difference between a struct and a class is the default access level, which is ''private'' for classes and ''public'' for structs. Note that while classes and the class keyword were completely new in C++, the C pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Synchronisation
Synchronization is the coordination of events to operate a system in unison. For example, the conductor of an orchestra keeps the orchestra synchronized or ''in time''. Systems that operate with all parts in synchrony are said to be synchronous or ''in sync''—and those that are not are '' asynchronous''. Today, time synchronization can occur between systems around the world through satellite navigation signals and other time and frequency transfer techniques. Navigation and railways Time-keeping and synchronization of clocks is a critical problem in long-distance ocean navigation. Before radio navigation and satellite-based navigation, navigators required accurate time in conjunction with astronomical observations to determine how far east or west their vessel traveled. The invention of an accurate marine chronometer revolutionized marine navigation. By the end of the 19th century, important ports provided time signals in the form of a signal gun, flag, or dropping tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Concurrency (computer Science)
In computer science, concurrency is the ability of different parts or units of a program, algorithm, or problem to be executed out-of-order or in partial order, without affecting the outcome. This allows for parallel execution of the concurrent units, which can significantly improve overall speed of the execution in multi-processor and multi-core systems. In more technical terms, concurrency refers to the decomposability of a program, algorithm, or problem into order-independent or partially-ordered components or units of computation. According to Rob Pike, concurrency is the composition of independently executing computations, and concurrency is not parallelism: concurrency is about dealing with lots of things at once but parallelism is about doing lots of things at once. Concurrency is about structure, parallelism is about execution, concurrency provides a way to structure a solution to solve a problem that may (but not necessarily) be parallelizable.

System Description Language
A system is a group of interacting or interrelated elements that act according to a set of rules to form a unified whole. A system, surrounded and influenced by its environment, is described by its boundaries, structure and purpose and expressed in its functioning. Systems are the subjects of study of systems theory and other systems sciences. Systems have several common properties and characteristics, including structure, function(s), behavior and interconnectivity. Etymology The term ''system'' comes from the Latin word ''systēma'', in turn from Greek ''systēma'': "whole concept made of several parts or members, system", literary "composition"."σύστημα" Henry George Liddell, Robert Scott, '' |
