SPI Example

a real data:
1st:
work n chip1
{576'hc16801619d8d4242e06e5fab25a54bbe222e8b877848c34beea79cd6528caf7e33cde02a983dab158119ce2a1c9fc4eddac8ce296d0fd9da6e18f645087e051a2d547050e8dc86b1, 64'ha, 32'h1, 32'h1, 32'h1} 
work n chip0
{576'h1bed3ba0a2cb45c1d8f8ef6712146495c44192c07145fd6d974bf4bb8f41371d65c90d1e9cb18a17fa77fe7d13cdfd7b0063910762a5f25c06b168ae087e051a895170504ac1d001, 64'h5, 32'h1, 32'h1, 32'h1}

2nd:
work n+1 chip1
{576'h0, 64'hb, 32'h1, 32'h1, 32'h1}
work n+1 chip0
{576'h0, 64'h6, 32'h1, 32'h1, 32'h1}

3rd:
work n+2 chip1
{576'h0, 64'hc, 32'h1, 32'h1, 32'h1}
work n+2 chip0
{576'h0, 64'h7, 32'h1, 32'h1, 32'h1}

then get nonce 32'h1beebba0 for chip0, 32'hc1698161 for chip1;

Avalon4

Each module include 40 A3222 ASICs, the mdoule should be working at 1TH/S and using 700W power.
