What is HLS tool?
The Intel® HLS Compiler is a high-level synthesis (HLS) tool that takes in untimed C++ as input and generates production-quality register transfer level (RTL) code that is optimized for Intel® FPGAs. This tool accelerates verification time over RTL by raising the abstraction level for FPGA hardware design.
What is meant by high level synthesis?
High level synthesis (HLS) [1], also known as behavioral synthesis and algorithmic synthesis, is a design process in which a high level, functional description of a design is automatically compiled into a RTL implementation that meets certain user specified design constraints.
What is high level synthesis in FPGA?
Overview. The Intel® HLS Compiler is a high-level synthesis (HLS) tool that takes in untimed C++ as input and generates production-quality register transfer level (RTL) code that is optimized for Intel® FPGAs. This tool accelerates verification time over RTL by raising the abstraction level for FPGA hardware design.
What is the meaning of synthesising higher abstraction?
high-level synthesis
Hardware can be designed at varying levels of abstraction. While logic synthesis uses an RTL description of the design, high-level synthesis works at a higher level of abstraction, starting with an algorithmic description in a high-level language such as SystemC and ANSI C/C++.
What is SystemC model?
SystemC is a set of C++ classes and macros which provide an event-driven simulation interface (see also discrete event simulation). In certain respects, SystemC deliberately mimics the hardware description languages VHDL and Verilog, but is more aptly described as a system-level modeling language.
What is HLS vs RTL?
High-level synthesis (HLS) and register transfer level (RTL) are two popular methods to design FPGAs. On the other hand, RTL development enables the developer to make lower level design decisions which can increase the performance and efficiency of the system.
Is SystemC a HDL?
SystemC -> This is a C++ class library that effectively introduces the concept of time in C++ and allows you to do an event driven simulation. Clearly it is a lot more high-level than any HDL and things here can be implemented much quicker.
Why is SystemC used?
SystemC can help increase productivity by offering a more abstract way of defining a system than is available using hardware description languages (HDLs) such as Verilog and VHDL. The abstract nature of SystemC enables systems to be specified independent of their implementation.
What is RTL synthesis?
In computer engineering, logic synthesis is a process by which an abstract specification of desired circuit behavior, typically at register transfer level (RTL), is turned into a design implementation in terms of logic gates, typically by a computer program called a synthesis tool.
What is HLS stand for?
HTTP live streaming
The acronym HLS stands for HTTP live streaming. Use this tool, and you can deliver video and audio to a massive audience tapped in via the internet.
Is SystemC used?
While such languages are often used for Register Transfer Level descriptions, SystemC is generally applied to system-level modelling, architectural exploration, software development, functional verification, and high-level synthesis.
Is SystemC a language?
The Language for System-Level Modeling, Design and Verification. SystemC® addresses the need for a system design and verification language that spans hardware and software. It is a language built in standard C++ by extending the language with the use of class libraries.
How does a high level synthesis tool work?
The high-level synthesis tools handle the micro-architecture and transform untimed or partially timed functional code into fully timed RTL implementations, automatically creating cycle-by-cycle detail for hardware implementation.
How does Stratus high level synthesis ( HLS ) work?
With Cadence® Stratus™ High-Level Synthesis (Stratus HLS), engineering teams can quickly design and verify high-quality RTL implementations from abstract IEEE 1666 synthesizable SystemC®, C, or C++ models. The models can be easily created using the Stratus integrated design environment (IDE).
What’s the difference between logic synthesis and high-level synthesis?
While logic synthesis uses an RTL description of the design, high-level synthesis works at a higher level of abstraction, starting with an algorithmic description in a high-level language such as SystemC and ANSI C/C++. The designer typically develops the module functionality and the interconnect protocol.
When did high level synthesis start in the US?
Adoption in the United States started in earnest in 2008. The most common source inputs for high-level synthesis are based on standard languages such as ANSI C / C++, SystemC and MATLAB .
