HN comment orderhttps://bellard.org/tinyemu/readme.txt : > 4.1) 128 bit support > The RISC-V specification does not define all the instruction encodings for the 128 bit integer and floating point operations. The missing ones were interpolated from the 32 and 64 ones. > Unfortunately there is no RISC-V 128 bit toolchain nor OS now (volunteers for the Linux port ?), so rv128test.bin may be the first 128 bit code for RISC-V !
Interestingly the VM seems to have internet access via a DigitalOcean instance: > Access to Internet is possible inside the emulator. It uses the websocket VPN offered by Benjamin Burns (see his blog[0]). The bandwidth is capped to 40 kB/s and at most two connections are allowed per public IP address. Please don't abuse the service. [0] http://www.benjamincburns.com/2013/11/10/jor1k-ethmac-suppor...
>"TinyEMU is a system emulator for the RISC-V and x86 architectures. Its purpose is to be small and simple ( <- PDS: Very Important!!!) while being complete. Main features: o RISC-V system emulator supporting the RV128IMAFDQC base ISA (user level ISA version 2.2, priviledged architecture version 1.10) including: o 32/64/128 bit integer registers o 32/64/128 bit floating point instructions (using the SoftFP Library) o Compressed instructions o Dynamic XLEN change o x86 system emulator based on KVM o VirtIO console…
