Title: "Efficient Bitcoin Miner System Implemented on Zynq SoC" Post by: ztex on July 25, 2013, 07:01:39 AM Here is an interesting article about an "Efficient Bitcoin Miner System Implemented on Zynq SoC": http://www.xilinx.com/publications/archives/xcell/Xcell84.pdf

Seems that they were able to get up to 3.8 Mh/s with a single core implemented. I didn't see any mention of how much headroom they had left on the SOC to implement additional cores. Maybe its only one core per chip. You need a lot more cores though to make it viable in today's world. Wonder if Scrypt could be made to work on the ZedBoard?

Thanks for your history lesson, but I am referring to the "soft" mining core in the Programmable logic block of the Zynq-7000 discussed in the article. Not hard-wired CPU cores. ;D They referenced utilizing multiple mining cores connected to the embedded bitcoind node, but they did not expand on if they were able to create multiple soft cores on a single Zynq-7000. Just a curiosity. As it would need about a 100 cores just to equal the hashing power of a USB block erupter. hahaha!

The high-level synthesis tool they used made their life easier, but their hasher is nowhere near as fast as it should be...
As for the Zedboard - it is cool, once you get over the learning curve of handling both the CPU/Linux and FPGA flow, but unfortunately the board seems to be lacking a bit in the PSU department - I managed 38MH/s on mine but while there was more room for hashers, adding anymore would brown it out!
