Title: ASIC: 1Hz=1hash ?
Post by: jiangchun on January 08, 2013, 05:54:35 AM
I had read the VHDL source code,it's 1Hz=1hash;
So the avalon is about 256Mhz/chip, ASICMINER also ,means that the ASIC one chip is about 300Mhash/s ?
and the avalon speed is about 72G,so they need  totoal chips is about 200pcs?

It depends on the design. It's pretty standard to produce a pipelined hashing "core" that will indeed do 1 hash per clock, but it's possible to pack several on one chip. Also, I suspect that clock rates can be pushed way higher than 256Mhz with sufficient cooling.

Don't forget it could be multiple stream line, so multiple works can be done in parallel.
