* the initial support of synopsys designware ARC processor using embARC_BSP, all synopsys ARC-based boards are supported: -ARC Software Development Platform -ARC EM Starter Kit -ARC EM Software Development Platform -ARC HS Development Kit -ARC IoT Development Kit * The embARC BSP is a new generation embARC software development package. It is designed to be the inter-layer between hardware and operating system. BSP could hide the difference of hardware/boards, provide a unified interface to upper-layer. * the initial support of synopsys MWDT toolchain. The DesignWare® ARC® MetaWare Development Toolkit builds upon a 25-year legacy of industry-leading compiler and debugger products. It is a complete solution that contains all the components needed to support the development, debugging and tuning of embedded applications for the DesignWare ARC processors. * for detailed board information, pls go embarc.org.
