Expansion Board Enhances Popular RISC-V Development Board

Microsemi’s HiFive Unleashed Expansion Board is the result of the company’s collaboration with SiFive. The expansion board broadens the capabilities of SiFive's HiFive Unleashed RISC-V development board, enabling software and firmware engineers to write Linux-based applications targeting a 1GhZ+ RISC-V 64-bit central processing unit (CPU).

 

Microsemi's HiFive Unleashed Expansion Board allows developers to implement custom peripherals in the PolarFire field programmable gate array (FPGA). They can implement a full-fledged RISC-V personal computer (PC) by enabling standard PCI Express (PCIe) devices, USB and secure digital cards to connect to SiFive's Freedom U540 RISC-V processor.

Embedded Technologies Expo & Conference

The inaugural event will take place June 25-27 in San Jose, CA!

Embedded Technologies Expo & Conference (ETC), in the largest embedded and IoT market in North America, is the ONLY event focused on what is most important to designers and implementers – education and training. Attendees will experience over 100 hours of unparalleled education and training covering embedded systems, IoT, connectivity, edge computing, AI, machine learning, and more. Co-located with Sensors Expo & Conference, attendees will have the opportunity to see hundreds of leading exhibitors and network with thousands of industry peers and innovators.

 

The HiFive Unleashed Expansion Board and HiFive Unleashed allow designers to develop complete Linux applications on a modern RISC-V CPU running at 1 GHz+. This makes the devices suitable for a variety of embedded applications within the communications, industrial, defense, medical and avionics markets, including control plane solutions, imaging/video processing, machine learning, control processing, time-sensitive networking, encryption and root of trust, secure wireless communications and aircraft networking.

Features include a PCIe root complex, serial advanced technology attachment (SATA) port, M.2 SSD port, two USB ports, HDMI, double data rate fourth-generation (DDR4) memory expansion, an embedded multi-media controller (eMMC) managed NAND Flash, and secure digital card slot.

 

RISC-V is a free and open ISA enabling a new era of processor innovation through open standard collaboration. As the ISA is frozen, software which is written will always run on the RISC-V core, and since the RISC-V IP core is not encrypted, it can be used to ensure trust and certifications not possible with closed architectures.  To learn more about RISC-V visit, you guessed it, RISC.

 

The HiFive Unleashed Expansion Board and HiFive Unleashed development board are available for purchase from Crowd Supply. For more information, visit Microsemi.
