New specification of risc-v chip architecture

RISC-V International Normative and extended （40 Multiple extended 16 Specifications were approved ）

        RISC-V Efficient Trace (E-Trace)、

        RISC-V Supervisor Binary interface (SBI)、

        RISC-V Unified extensible firmware interface (UEFI) standard ,

RISC-V Zmmul multiply-only Expand .

RISC-V The new specification accelerates embedded and large-scale system design .“ Debugging is one of the hardest things to do on a chip , be used for RISC-V Of E-Trace Created a standard way to trace processors , Very efficient and especially useful in embedded system design .RISC-V SBI Provides equally important resources for developers . In all RISC-V Migration in implementation supervisor-mode Software capabilities , It basically allows developers to write code once and apply it anywhere
