Syntacore's SCR RISC-V IP Now Supports Zephyr 4.3
April 21, 2026 -- Syntacore, a RISC-V processor IP and software tools specialist, announces full support for Zephyr 4.3 Real-Time Operating System (RTOS) in its SCR RISC-V IP portfolio.
Major features:
Added support for CLIC, ACLINT, and AIA (ACLINT+IMSIC) interrupt controllers- Implemented PMA Checker support
- Enabled support for Syntacore generic cache L2 and L3
- Implemented Syntacore GCC and LLVM (clang) compiler support
- Incorporated new extensions: Bitmanip, Scalar Crypto, and zicbom
Zephyr OS is pre-configured and tested for SCR cores, allowing developers to easily deploy real-time embedded applications. The operating system is ready to use out-of-the-box, supports multi-core configurations, and is regularly updated with professional technical support available.
To get Zephyr 4.3, please contact our sales/FAE team.
