In the dynamic landscape of embedded systems, the intersection of open-source RISC-V architectures and Field-Programmable Gate Arrays (FPGAs) signifies a monumental leap toward achieving flexibility, power efficiency, and performance optimization. Spearheading this evolution, Microchip Technology Inc. introduces the PolarFire® System-on-Chip (SoC) Discovery Kit.
This development platform is meticulously crafted to democratize access to pioneering RISC-V and FPGA technologies, catering to a wide spectrum of engineers—from novices to seasoned professionals. Let’s dive into the technical specifics that position this kit as a cornerstone for the future of embedded engineering.
At the heart of the PolarFire SoC Discovery Kit lies the PolarFire MPFS095T SoC FPGA. This multi-core processor harnesses the power of the open-source RISC-V Instruction Set Architecture (ISA), featuring a quad-core, 64-bit CPU cluster designed to meet the demands of applications requiring substantial computational power and efficiency. With support for both Linux® and real-time operating systems, the SoC offers a versatile platform for developing intricate embedded systems.
A hallmark of the PolarFire SoC is its 95K low-power, high-performance FPGA logic elements (LEs). These LEs provide designers with the capability to implement custom digital logic, ranging from simple glue logic functions to sophisticated system-level integrations, including custom peripherals or parallel processing algorithms. This FPGA functionality is crucial for applications necessitating specific, optimized hardware accelerators or bespoke interfaces.
The embedded microprocessor subsystem boasts a substantial L2 memory subsystem that can be configured for either peak performance or deterministic operation, supporting asymmetric multi-processing (AMP) mode. This adaptability allows designers to strike a balance between high-speed data processing and the deterministic behavior required for real-time applications. Additionally, the kit includes a microSD™ card slot for booting Linux.
The Discovery Kit is equipped with a comprehensive suite of peripherals and connectivity options to ensure its applicability across various embedded system projects:
mikroBUS™ Expansion Header: Facilitates easy integration with Click boards™, offering a vast array of sensors, transceivers, and interface boards for rapid prototyping.
40-pin Raspberry Pi® Connector: Ensures compatibility with a broad range of HATs, allowing for extensive I/O expansion.
MIPI® Rx Video Connector: Supports video applications, enabling direct connection to cameras and displays for multimedia projects.
Communication Interfaces: Includes one Gigabit Ethernet connector and three UART connections via a USB type C connector.
An on-board FlashPro5 programmer is integrated for programming and debugging the PolarFire FPGA via a USB-to-JTAG channel. This streamlines the firmware development process. The kit also provides a DSP FIR Filter reference design for immediate testing, and designers can utilize Microchip’s Libero® SoC design suite software with a free Silver License, which includes the necessary device programmer drivers.
