Codasip announces RISC-V processor cores providing multi-core and SIMD capabilities

Codasip, a supplier of customisable RISC-V processor IP, has unveiled three new 64-bit RISC-V application processor cores: the A70XP, the A70X‑MP and the A70XP‑MP that provide extensions for RISC-V P extensions and enable the creation of symmetric multi-processor (SMP) systems.

The RISC-V P extension consists of 331 instructions which can be divided into groups. The A70XP includes a SIMD unit which executes P extension instructions with single-cycle latency. Multi-cycle instructions are pipelined to allow one to be executed every clock cycle. Applications include: audio encoding/decoding, sensor fusion, computer vision, and edge AI/ML applications.

The A70X-MP and A70XP-MP cores add multi-core features to the Codasip application processor family, supporting clusters of up to four cores in an SMP configuration. Codasip provides configurable L1 and L2 caches with a scalable microarchitecture. All Codasip application processors – the A70X, A70XP, A70X-MP, and A70XP-MP – use an AXI external interface and support Linux.

Codasip’s new family of Application RISC-V processors (names beginning with “A”) is based on the same microarchitecture as the A70X (Codasip Bk7). All the Application cores are 64-bit and feature a Floating Point Unit and Atomic instructions. They also support Machine, Supervisor & User privilege modes and have a Memory Management Unit, therefore they are able to run Linux. Like other Codasip RISC-V cores, they are developed using Codasip Studio allowing them to be customized to meet domain-specific requirements.

“We are delighted to extend our range of Codasip RISC-V application processors with cores offering higher performance,” said Karel Masařík, CEO Codasip. “These new cores are the combined work of our new French Design Centre and our main R&D Centre in Brno. They will be followed by more exciting new products in 2021.”

The A70X core is available today and the other three cores will be available in the first quarter of 2021.
