Its just an ISA right?

How did we get here?

February 2019 RISC-V Foundation 22 RISC-V Background

. Started as a research project at UC Berkeley in 2010 and resulted in the release of the base user spec in May, 2014 - many tapeouts and several research publications along the way . The name RISC-V (pronounced risk-five), was chosen to represent the fifth major RISC ISA design effort at UC Berkeley - RISC-I, RISC-II, SOAR, and SPUR were the first four projects with the original RISC-I publications dating back to 1981 . In August 2015, articles of incorporation were filed to create a non-profit RISC-V Foundation to govern the ISA

February 2019 RISC-V Foundation 23 Most CPU chips are SoCs with many ISAs

. Applications processor . Graphics processors . Image processors . Radio DSPs . Audio DSPs . Security processors . Power-management processor . …. NVIDIA Tegra SoC

. Apps processor ISA too large for base accelerator ISA . IP bought from different places, each proprietary ISA . Home-grown ISA cores . Over a dozen ISAs on some SoCs – each with unique software stack

February 2019 RISC-V Foundation 24 Why so Many ISAs? Do we need all these different ISAs?

Must they be proprietary?

What if there was one free and open ISA everyone could use for everything?

February 2019 RISC-V Foundation 25 What’s Different about RISC-V?

. Simple - Far smaller than other commercial ISAs . Clean-slate design - Clear separation between user and privileged ISA - Avoids µarchitecture or technology-dependent features . A modular ISA - Small standard base ISA - Multiple standard extensions . Designed for extensibility/specialization - Variable-length instruction encoding - Vast opcode space available for instruction-set extensions . Stable - Base and standard extensions are frozen - Additions via optional extensions, not new versions

February 2019 RISC-V Foundation 26 Summary

. The free and open RISC-V ISA is enabling a new innovation frontier across all computing devices . Strong Industry Support - ~200+ members; Broad commercial and academic interest .

February 2019 RISC-V Foundation 27 FreeRTOS on RISC-V

Pre-configured examples: • QEMU sifive_e model using Freedom Studio • Microsemi/Future Electronics M2GL025-Creative-Board using SoftConsole • VEGAboard using vanilla Eclipse (https://www.open-isa.org)

FreeRTOS RISC-V specifics: • Including the source files • Setting the assembler’s include file • Set configCLINT_BASE_ADDRESS • #define portasmHANDLE_INTERRUPT • Install the FreeRTOS trap hander
