Dragon Li’s Bajiu Lite Is a Versatile FPGA Improvement Board with RISC-V SoC Capabilities

FPGA specialist Dragon Li Studio is trying to launch a “resource-rich” open supply improvement board with an built-in RISC-V system-on-chip (SoC): the Bajiu Lite.

“Bajiu Lite is a resource-rich FPGA improvement board with 20k LE [Logic Elements], 36 multipliers, and as much as 5 PLLs [Phase-Locked Loops],” the corporate explains of its design. “It may simply run at frequencies above 150MHz with very low energy consumption. It’s small, handy and devoted to facilitating speedy FPGA improvement proper out of the field.”

It is also not simply an FPGA: the board is designed to play host to a customized RISC-V improvement system dubbed CRiscV, based mostly on the VexRiscv venture — giving the consumer, Dragon Li claims, a fast path to implementing a spread of workloads from pc imaginative and prescient processing and on-device neural networks to robotics and different real-time management methods.

CRiscV implements the 32-bit RV32I with optionally available MAFDC instruction set structure, with pipelining from two to 5 or extra phases, department prediction, cache for directions and information, a devoted multiplication and division unit, and debugging capabilities appropriate with OpenOCD.

The Bajiu Lite board itself, in the meantime, presents slightly below 20k logic parts, 36 multipliers, 5 PLLs, and 1MB of embedded RAM from an Efinix Trion T20F169 FPGA, one every of MIPI Digital camera Serial Interface (CSI) and Show Serial Interface (DSI) ports, three LEDs, three buttons, ten general-purpose enter/output (GPIO) pins, 128Mb of flash, two UART buses, and JTAG debug assist.

“Enjoyable reality: ‘Bajiu’ means 8 * 9 = 72, which implies the legendary Monkey King’s thousand variations,” Dragon Li explains of the board’s moniker. “We selected this title as a result of you should use Bajiu Lite to implement any logic.”

Extra data on the venture is accessible on the Bajiu Lite GitHub repository, the place CRiscV and instance supply code is made accessible below the reciprocal GNU Basic Public License 3. Dragon Li can be planning to promote boards by Crowd Provide, however has not but confirmed a marketing campaign launch date nor pricing.
