A flexible FPGA development board with RISC-V SoC capabilities is called Dragon Li's Bajiu Lite.

 Users can modify the VexRiscv CRiscV soft-core to suit workloads ranging from robotics to computer vision.

A flexible FPGA development board with RISC-V SoC capabilities is called Dragon Li's Bajiu Lite.

The Bajiu Lite, an open-source development board with an embedded RISC-V system-on-chip (SoC), is being prepared for release by FPGA specialist Dragon Li Studio.

According to the manufacturer, "Bajiu Lite is a resource-rich FPGA development board with 20k LE [Logic Elements], 36 multipliers, and up to 5 PLLs [Phase-Locked Loops]." "With relatively little power consumption, it can easily operate at frequencies beyond 150MHz. It is compact, practical, and built from the ground up to promote rapid FPGA development."

Features & Specifications

  • 20,000 LEs
  • 1 Mb RAM
  • 36 Multipliers
  • 5 PLLs
  • 1 MIPI CSI
  • 1 MIPI DSI
  • 3 LEDS
  • 3 Buttons
  • 10 GPIOs
  • 128 Mbits Flash
  • 2 UART interfaces
  • FTDI JTAG Debugger

 A custom RISC-V development system called CRiscV, based on the VexRiscv project is built into the board, making it more than just an FPGA. According to Dragon Li, this gives users a quick way to implement a variety of workloads, including computer vision processing, on-device neural networks, robotics, and other real-time control systems.

With pipelining ranging from two to five stages, branch prediction, a specialized multiplication, and division unit, and debugging facilities compatible with OpenOCD, CRiscV implements the 32-bit RV32I with optional MAFDC instruction set architecture.

A little under 20k logic elements, 36 multipliers, five PLLs, 1MB of embedded RAM, one MIPI Camera Serial Interface (CSI) port and one Display Serial Interface (DSI) port, three LEDs, three buttons, ten general-purpose input/output (GPIO) pins, 128Mb of flash, two UART buses, and JTAG debug support are all included on the Bajiu Lite board itself.

Dragon Li explains the meaning behind the name of the board: "Fun fact: 'Bajiu' means 8 * 9 = 72, which signifies the famous Monkey King's thousand varieties." "We picked this moniker since Bajiu Lite can implement any logic," the author said.

The Bajiu Lite GitHub repository has further details on the project and provides CRiscV and sample source code under the reciprocal GNU General Public License 3. Dragon Li also intends to offer boards via Crowd Supply, but neither a launch date nor a price has been made official.
