SmartHLS Tool Suite enables C++ Based Algorithm Development using Microchip’s PolarFire FPGA Platform

Enhances accessibility to PolarFire FPGAs for hardware acceleration in edge compute systems

The need to combine performance with low power consumption in edge compute applications has driven demand for Field Programmable Gate Arrays (FPGAs) to be used as power-efficient accelerators while also providing flexibility and speeding time to market. However, a large majority of edge compute, computer vision and industrial control algorithms are developed natively in C++ by developers with little or no knowledge of underlying FPGA hardware. To enable this important development community, Microchip Technology Inc. has added an HLS design workflow, called SmartHLS, to its PolarFire FPGA families that greatly enhances productivity and ease of design by allowing C++ algorithms to be directly translated to FPGA-optimized Register Transfer Level (RTL) code.  

SmartHLS enhances our Libero SoC design tool suite and makes the vast benefits of our award-winning mid-range PolarFire and PolarFire SoC platforms accessible to a diverse community of algorithm developers without them having to become FPGA hardware experts,” said Bruce Weyer, vice president of Microchip’s FPGA business unit. “Together with our VectorBlox Neural Network Software Development Kit these tools will greatly improve designers’ productivity in creating cutting-edge solutions using C/C++ based algorithms for applications such as embedded vision, machine learning, motor control and industrial automation using FPGA-based hardware accelerators.” 

Based on the open-source Eclipse integrated development environment, the SmartHLS design suite uses C++ software code to generate an HDL IP component for integration into Microchip’s Libero SmartDesign projects. This enables engineers to describe hardware behavior at a higher level of abstraction than is possible with traditional FPGA RTL tools. It further improves productivity while reducing development time through a multi-threading Application Programming Interface (API) that executes hardware instructions concurrently and simplifies the expression of complex hardware parallelism as compared to other HLS offerings.  

The SmartHLS tool requires up to 10 times fewer lines of code than an equivalent RTL design, with the resultant code being easier to read, understand, test, debug and verify. The tool also simplifies exploration of hardware microarchitecture design trade-offs and enables a developer’s pre-existing C++ software implementations to now be used with PolarFire FPGAs and FPGA SoCs. 

About the PolarFire FPGA Family 

PolarFire FPGAs and FPGA SoCs solve difficult edge compute system design challenges by offering the industry’s lowest power at mid-range densities. The company recently announced low-density additions to its family that, by consuming half the static power of alternatives and providing the world’s smallest thermal footprint, enable developers to reduce system costs and meet thermal management requirements without forfeiting bandwidth. These new FPGAs as well as the company’s SmartFusion 2 FPGA and IGLOO 2 FPGA are also supported by the new tool. 


Developers can initiate designs now using the SmartHLS v2021.2 tool, which is available on the Microchip website. It is part of the recently released Libero SoC V2021.2 design suite and can also be used as stand-alone software. Complete product information is available here.
