IOTA hardware accelerator

FPGA based hardware accelerator for IOTA Curl and POW operations written in Verilog/System Verilog

This project created for Innovate FPGA Contest: Design video, Design paper

Performance & Resources:

• Parameterized design. Parameter CL_NUM specifies the number of POW clusters. Parameter CU_NUM defines the number of POW computing units per cluster
• Hardware resources: 1 200 ALMs, 2 400 flip-flops per POW computing unit
• Hashrate: 1 204 819 hash/sec per POW comput. unit at 100 MHz
• Fmax: 130-140 MHz for Cyclone V depending on number of POW comput. units

Proof-of-Concept launched on DE10-nano board (Cyclone V 5CSEBA6U23I7 FPGA device) which costs 110-130$

PoC parameters:

• 28 POW computing units (CL_NUM = 7, CU_NUM = 4)
• Operation frequency: 100 MHz
• Hashrate: 33 734 940 hash/sec
• Resources: 33 239 ALMs, 68 019 flip-flops (79% of 5CSEBA6U23I7 FPGA)
• POW acceleration: x2000 (for MWM=15 software POW on DE10-nano: 10-50 min, hardware accel. POW: 0.01-1.5 sec, 0.4 sec in average)

Download Linux sd-card image for IOTA hardware accelerator on DE10-nano board and latest rbf file

Arrow SoCKit board

Build instructions mentioned RBF file for Arrow SoCKit board. For the sake of consistency, we host FPGA related repository under DLTcollab umbrella.

Generate the RBF file

• Install Intel Quartus Prime Lite Edition 17.1 and run synthesizing
• Transform SOF file to RBF file

 ~/intelFPGA_lite/17.1/quartus/bin/quartus_cpf -c curl_fpga.sof soc_system.rbf

Quickly start from scratch

• Download Linux sd-card image for Cyclone V
• The RBF file for Arrow SocKit board
• Creating an SD Card using a Linux Host

$ sudo dd if=DE10_iota_fpga_Linux.img of=/dev/sdb bs=2048
$ sudo sync

• Overwrite the RBF file in the SD card

$ sudo mkdir sdcard
$ sudo mount /dev/sdb1 sdcard/
$ sudo cp soc_system.rbf sdcard/
$ sudo umount sdcard

• Connect to remote shell (account/password: root/123456)

$ ssh root@192.168.1.102
