RISC-V at Embedded World 2022

NOEL-V is a is a RISC-V processor model that can be implemented in various configurations ranging from RV32I to RCV64GC. The NOEL-V processor has been developed by the CAES Gaisler Products group, with a long heritage of supplying processor implementations - both as IP cores for general licensing, as well as radiation-tolerant standard products for space applications. The NOEL-V processor was initially released for general applications in 2019. A more recent addition to the core is the fault tolerant (FT) feature for high-reliability and space applications, which has heritage in numerous previous processor generations. Along with the introduction of the NOEL-V IP, the presentation will describe the first implementations from a single-core testchip to the GR7xV development, a 16-core NOEL-V based processor targeted towards space applications. Furthermore, the ongoing evolution of the IP is demonstrated e.g. in terms of support for different extensions of the RISC-V ISA and the resulting impact on parameters such as implementation complexity.
