IP Core


FIE310G is a high performance, low power embedded real time RISC-V processor IPCore.

The main application areas aim at smart home, Wearable, sensor Fusion, IOT, and industrial control etc.


  1. Fully supports the RV32IMFAC instruction architecture and provides a rich set of storage and interfaces, including: ITCM 64K(Instruction Tightly Coupled Memories) and DTCM 64K(Data Tightly Coupled Memories) for separate storage of instructions and data, and 2M bytes External super RAM support as well .
  2. 3-stage pipeline architecture
  3. support machine mode only
  4. From instruction fetch ,Decoder ,Execution to memory operation modules are 100% Manually developed by using pure verilog HDL, scalable and easy to be understood.
  5.  The flexible RISC-V IPCORE is suitable for customized ASIC for specific domain, Also can be used as embedded CPU with in FPGA.
  6.  Interrupt controller, supports 16 high-priority, low-latency local vectored interrupts.
  1. includes a RISC-V standard PLIC (platform-level interrupt controller ), which supports 127 global interrupts with 7 priority levels. provides the standard RISCV machine-mode timer and software interrupts via the CLINT(Core Local Interruptor)
  2. 2 UART
  3. 3 QSPI
  4. I2C
  5. 3 PWM
  6. 10M/100M/1G ethernet
  7. Watchdog
  8. 32 GPIO
  9. 4 7-seg display interface
  10. External Serial Flash
  11. Debug Interfaces: JTAG
  12. 12-Bit ADC
  13. Four data lines I2S and can support maximum of 8 audio outputs or 4 stereo channels
  14. Hardware Crypto Engine for Advanced Fast Security, Including: AES 128, CRC, Checksum etc

The entire system is designed by the verilog language, and all IPs can be added, deleted and reconfigured.
