MMX - Miner Manager with Exstension

Miner Manager is a stratum task generator firmware that fit FPGA and ASIC miners.

Main objectives

• It is using stratum protocol
• It generate the tasks (block headers) inside FPGA. all Double-SHA256 was done by FPGA, far more faster than CPU.
• Test the nonce inside the FPGA. only report the >= DIFF tasks back to the host (CGMiner)
• It fits any kinds of stratum mining ASIC, (you may needs some VerilogHDL coding)
• It has a LM32 CPU inside, fit in XC6SLX16 small FPGAs
• The MM datasheet: http://downloads.canaan-creative.com/software/mm/MM_SOC_Specification.pdf

Directory structure

• firmware: C codes running in LatticeMico32 soft processor
• ipcores_dir: IP cores
• synth: Directory for synthesize and build of the hardware part
• verilog: The VerilogHDL source code

How to build?

First you need install the ISE for sure. then edit the isedir under xilinx.mk by default we are using /home/Xilinx/14.6/ISE_DS/

For build the toolchain for lm32-rtems, it meets some problems with gcc-5.2.1 under Ubuntu and gcc-4.9.2 under Debian, for fix that, just switch to gcc-4.8 with CC=gcc=4.8 make ... and you also need texinfo_4.13a for fix the gdb build.

1. $ make -C firmware/toolchain # Install the lm32-rtems-4.11- toolchain under /opt
2. $ make -C firmware # Generate the final bitstream file .bit/.mcs under firmware/
3. $ make -C firmware load # Load the config bit file to FPAG by using Xilix Platform cable
