Target Markets
Machine Learning
The Avispado core, with its small area and power, is ideal for energy-conscious SOCs targeting Machine Learning.
If your next SoC is targeting the Machine Learning market, then Avispado’s small footprint combined with its ability to talk to a RISC-V Vector Unit (1.0) is the perfect fit for your target.
Combined with our Gazzillion technology, Avispado can deal with very high sparsity in tensor weights, resulting in excellent Energy per operation.
Recommendation Systems
The Gazzillion technology is specifically designed for Recommendation Systems, a key part of DataCenter Machine Learning.
By supporting hundreds of misses per Avispado, you can build an SoC that smoothly delivers highly sparse data to compute engines without a large silicon investment.
64-bit Core
Ready for the most demanding workloads, Avispado supports large memory capacities with its 64-bit native data path. With its complete MMU support, Avispado is also Linux-ready, including multiprocessing.
Vector Ready
Avispado supports the RISC-V Vector Specification 1.0 as well as Semidynamics Open Vector Interface, giving you freedom of choice between your own custom Vector Unit and using Semidynamics offerings.
Vector Instructions densely encode lots of computations, thereby reducing energy per operation.
Vector Gather instructions support sparse tensor weights efficiently, helping machine learning workloads.
Multiprocessor Ready
Avispado supports cache-coherent Multiprocessing environments. Its native CHI interface can be tailored down to AXI, depending on your needs.
Be it 2, 4, or hundreds of cores, Avispado is ready for your next SOC.
Avispado Test Chip
EPAC1.0 Test Chip
The picture shows a 25mm2 GF22FDX test chip containing 4 Avispado RISC-V cores (inside the 4 blocks on the north-east; each block contains an Avispado core, an L2, a Vector Unit and a NOC crosspoint).
This test chip was done in the context of the European Processor Initiative (click here for further details).
