RISC-V Summit 2022

Explosive computation demand in AI, AR/VR, financial computing, and computational biology has driven innovations in computation acceleration technology. Exponential model size growth coupled with the torrent of model data inputs requires a new heterogenous computation platform to integrate innovations in the software programming model, compiler, networking technology, semiconductor process, and packaging technology. Ascalon high-performance RISC-V super-scalar processor is one of the Tenstorrent technological components to address such computational demands. Ascalon processor is an 8-wide decode O-o-O machine with advanced branch predictors, large ROB, and wide instruction execution pipelines with powerful vector units. A compact and efficient cache-coherent cluster contains many cores and a large shared cache. A hierarchical coherent fabric connects Ascalon clusters to form a high-performance ccNUMA computation platform. The platform can be used as composable chiplet elements with high-performance memory sub-systems and accelerators to create domain-specific hardware with industrial-leading price-performance solutions.
