Semidynamics and SignatureIP jointly offer Ips for RISC V based muticore AI chips

Date: 09/10/2023
Two emerging semiconductor IP vendors Semidynamics and SignatureIP have joined hands in offering fully-tested RISC-V, multi-core environment and CHI interconnect for the development Advanced multi-core RISC-V chips for AI and ML applications.

Semidynamics’ CEO and founder, Roger Espasa, said, “Working closely together with other members of the RISC-V community is one of the driving forces of RISC-V’s rapidly growing success. There is a natural synergy between the two companies that has resulted in a solution that enables cutting edge, multi-cores chips to be created. SignatureIP’s C-NoC CHI interconnect solution makes it very straightforward to lay out the Network on Chip (NoC) for multiple cores on a chip using our mature, proven technologies which minimizes risks and accelerates time to market.”

Semidynamics offers ultra high-bandwidth RISC-V processor IP cores namely Atrevido, a 64-bit RISC-V Core which is a multiprocessor ready and vector ready. The Atrevido 423 is particularly well suited for applications that require massive amounts of data. The Avispado from Semidynamics is a 64-bit RISC-V Core which is a multiprocessor ready. Semidynamics also offers technologies called "Gazzillion Misses" a solution to the memory latency problem. Semidynamics has equipped its Vector Unit with a high-performance, cross-vector-core network that provides all-to-all connectivity between the vector cores at high bandwidth, even for the very large, 32-vector core option.

SignatureIP’s Coherent NoC is a directory-based architecture with distributed home-node support and optional system level caches for high performance, where it delivers both performance and scalability across chiplets and also supports transport layer for chiplet communication.

SignatureIP is also providing a software tool called to automate generation of physically-aware NoC for a system. SignatureIP is supporting its customers with a simple licensing model, enabling process of evaluation, licensing, and implementation an easy task for SignatureIP’s customers.

Kishore Mishra, SignatureIP’s CTO, added, “Semidynamics revolutionized the 64-bit RISC-V processor with cores that are fully customizable using its ‘Open Core Surgery’ approach. This goes deep into the core and is not the tweakable approach typically found in Ips. Combining our technologies now enables multi-core chip designs to be created on this fully coherent RISC-V/CHI platform and then prototyping on an FPGA to demonstrate the integrated performance. We have fully tested them together to ensure compatibility and minimization of verification time”.
