IAR Systems updates RISC-V development tools

摘要

IAR Systems has announced a new version of the toolchain IAR Embedded Workbench for RISC-V. Version 1.20 adds support for the base instruction set RV32E and also the standard extension for Atomic operations (A).RISC-V provides OEMs, as well as SoC vendors, with the flexibility to design custom cores with the exact definitions needed for the application or product. Through optimisation technology, the Embedded Workbench helps developers ensure their applications fit the required needs and optimises the utilisation of on-board memory.Version 1.20 adds support for the base instruction set RV32E that targets smaller embedded devices with the register set reduced to half of what is available in RV32I. The standard extension for 'A' operations adds instructions that support atomic read, modify, and write actions to support synchronisation between different HW processes that access the same memory.
