“In addition to functional safety certification, both products are also compliant with ISO/SAE 21434, the international standard for cybersecurity in automotive development,” according to Codasip.
Both cores have a multi-issue in-order microarchitecture.
L735 includes error-correcting code on caches and tightly coupled memories, a memory protection unit, and supports RISC-V RERI for error reporting.
On top of these features, L739 open the door to ASIL-D by adding dual-core lock-step.
L735 and L739 were developed using Codasip’s intellectual property development process, which has been certified as compliant to ISO 26262 and ISO/SAE 21434 by TÜV SÜD.
CHERI variants are available on both products.
The company’s design automation tool ‘Codasip Studio’ was used for both processors to generate both hardware and software development kits from a single architectural description. “This approach ensures consistency and traceability – key requirements in safety-related design,” said Codasip.
Its 700 family, which includes L735 and L739, also supports ‘bounded customisation’ – the introduction of custom instructions and accelerators.
