What is HLS design?

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.

Which of the following advantages High Level Synthesis HLS provide in VLSI designers?

From the above example, following advantages of HLS can be easily observed: Higher level of abstraction, therefore, focus on algorithms. Trade Off between Area and timing is flexible as per requirement. Reusability is much easier.

What is Xilinx HLS?

Xilinx Vitis HLS (formerly Xilinx Vivado HLS) is a High-Level Synthesis (HLS) tool developed by Xilinx and available at no cost. Vitis HLS allows the user to easily create complex FPGA-based algorithms using C/C++ code.

What is HLS flow?

High-level synthesis (HLS) is a technology that assists with the transformation of a behavioral description of hardware into an RTL model. It is considered to be part of an electronic system level (ESL) design flow. The input description is an untimed description of functionality written in C, C++ or SystemC.

What is high-level synthesis in FPGA?

High-level synthesis (HLS) is a potential solution to increase the productivity of FPGA-based real-time image processing development. It allows designers to reap the benefits of hardware implementation directly from the algorithm behaviors specified using C-like languages with high abstraction level.

What are the stages of high-level synthesis?

Early academic work extracted scheduling, allocation, and binding as the basic steps for high-level-synthesis.

What is HLS for 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 HLS and RTL?

High-level synthesis (HLS) and register transfer level (RTL) are two popular methods to design FPGAs. Both of methods have advantages and disadvantages: HLS provides ease of development, and is less prone to error. Thus, it reduces the development time significantly when designing a hardware system.

Which type of languages are characterized by the highest level of synthesis?

The most common source inputs for high-level synthesis are based on standard languages such as ANSI C/C++, SystemC and MATLAB.

What is FPGA chip?

Essentially, an FPGA is a hardware circuit that a user can program to carry out one or more logical operations. Taken a step further, FPGAs are integrated circuits, or ICs, which are sets of circuits on a chip—that’s the “array” part.

What is VLSI and FPGA?

FPGA in VLSI stands for ‘Field Programmable Gate Array’, which is an integrated circuit that may be programmed to execute a tailored function for a particular purpose. FPGAs have become highly popular in the VLSI area. The code for FPGA programming is written in languages like VHDL and Verilog.

What is Xilinx software in VLSI?

Xilinx ISE (Integrated Synthesis Environment) is a discontinued software tool from Xilinx for synthesis and analysis of HDL designs, which primarily targets development of embedded firmware for Xilinx FPGA and CPLD integrated circuit (IC) product families. It was succeeded by Xilinx Vivado.
