'''Celerity''' is a custom [[RISC-V]]-based [[neural processor]] microarchitecture. The work is a joint effort by the Bespoke Silicon Group at the University of Washington, Cornell University, University of Michigan, and UC San Diego.

== Process technology ==
Celerity is fabricated on [[TSMC]] [[16 nm process]].

== Overview ==
Celerity is a university-based research chip designed for the [[acceleration]] of [[neural processor|artificial intelligence]]. The design and implementation of the chip was said to have taken just nine months through the use of agile development and leveraging existing [[open-source]] code. The design is intended to allow enough flexibility as AI workloads continue to evolve. Designed for [[TSMC]] [[16 nm process]], the chip integrates three separate tiers of architectures, each is progressively more specialized, less flexible, but more power-efficient. The first tier, the general-purpose tier, integrates five powerful [[RISC-V]] {{ucberkeley|Rocket}} [[cores]] capable of running an operating system and managing the rest of the SoC. The second tier, the massively parallel tier, integrates a [[massively parallel processor array|massive array]] of 496 parallel highly-efficient, but simple, [[RISC-V]] {{\\|Vanilla-5}} cores. The last tier is the specialization tier which integrates a specialized custom [[binarized neural network|BNN]] [[accelerator]].
