Building Solutions for Modern AI/ML

AI/ML Challenges

Commonly used embedded control processors lack compute resources needed to execute inference workloads efficiently. Dedicated accelerators can work well for CNN layers, however:

  • They may not work for modern neural networks
  • They can be difficult to program, may have immature tools
  • In-house solutions may be expensive to maintain

SiFive Intelligence is a better option: A high-performance control processor with scalable vector compute resources, all based on an open instruction set.  SiFive Intelligence is a scalable platform to meet ML processing requirements, from extremely low power to high-performance compute.

The SiFive Solution

SiFive Intelligence is an integrated software + hardware solution that addresses energy efficient inference applications. It starts with SiFive’s industry-leading RISC-V Core IP, adds RISC-V Vector (RVV) support, and then goes a step further with the inclusion of software tools and new SiFive Intelligence Extensions, vector operations specifically tuned for the acceleration of machine learning operations. These new instructions, integrated with a multi-core capable, Linux-capable, dual-issue microarchitecture, with up to 512b wide vectors, and bundled with TensorFlow Lite support, are well-suited for high-performance, low-power inference applications.
