I don’t know how anyone, but the past 2017 shocked me with the rapid rise of Bitcoin.Click here to view our very own wiki! More resources below.
Now, of course, the excitement has already left, and in the 17th year everyone spoke about and wrote about cryptocurrencies. I saw people trying to make money on cryptocurrencies.
Someone bought all the video cards for all the savings and began to mine in the garage on their own. Someone launched chocolate bitcoins into production, and someone produces mineral water: Someone is trying to organize their pool. I also began to study what these same bitcoins are. Once I even started my own research on the SHA256 algorithm and wrote an article here on the hub: " Is it possible to calculate bitcoins faster, easier or easier?". My research on hashing algorithms is still ongoing and still not nearly completed. Maybe someday I’ll write a separate article about it. I tried to run the bitcoin miner in FPGA. I realized that the time had already passed, but I still wanted to touch the technology.At the end of last year, for some reason I suddenly remembered that I was completely idle with the Terasic DE10-Standard motherboard with the Intel Cyclone V 5CSXFC6D6F31C6 FPGA - this is the chip that has an integrated ARM processor. I thought it would be interesting to launch some kind of altcoin miner this board. Why? Invest in equipment I no longer necessary, and so it is. What matters is that pay earned more than it consumes energy.įinding the right altcoin was quite simple. I was looking for ready-made projects for FPGA, which I can adapt to my board. In fact, as I understand it, there are only a few people around the world who have done FPGA projects and most importantly published them in the public domain, for example, on github. Thus, I took the /kramble/FPGA-Blakecoin-Miner project and adapted it to my existing Mars rover3 board, and also adapted this project for the DE10-Standard.Īctually, how I adapted the project for the Mars rover3 board is written here. For Cyclone V, in principle, everything is the same - only an revision of the quake project blake_cv, my sources are here. To my regret, only three hashes of the blake function are placed in my Cyclone V. There is a little lack of FPGA capacity for up to four hashes. I run a project at a frequency of 120 MHz and one blake hash is calculated in one clock cycle. So the productivity of my project is 120 * 3 = 360MH / sec. Not much honestly, however, as I said, I already had a board, and I do not need to return its cost.
#Cgminer 3.1.1 install#
The general idea of the project is this: the board has a chip that has both an FPGA and Dual-ARM: You can try to raise the frequency, but I'm afraid I will have to install a cooler, it will buzz - well, not so much I need these crypts to listen to another buzz in the room. When the board starts, the FPGA is first loaded from U-BOOT, then Linux starts and cgminer mining program is launched in it.
