## Executive summary

* Very high end RISC-V implementation – goal cloud server class

* Out of order, super scalar, speculative

* RV64-IMAFDCHBK(V)

* Up to 8 IPC (instructions per clock) peak, goal ~4 average on ALU heavy work, already past there

* 2-way simultaneous multithreading capable

* Multi-core

* Current dhrystone numbers: ~11.3 DMips/MHz - still a work in progress. 

* Currently boots Linux on an AWS-FPGA instance

* GPL3 – dual licensing possible
