Neural signal processing8/3/2023 ![]() ![]() While designed for the simplicity of a single-core approach, though, Quadric says multiple Chimera cores can be linked together for increased performance. Abstract A fully autonomous intracranial device is built to continually record neural activities in different parts of the brain, process these sampled signals, decode features that correlate to behaviors and neuropsychiatric states, and use these features to deliver brain stimulation in a closed-loop fashion. The entry-level QB1 offers 1 trillion operations per second (TOPS) of machine learning performance with 64 giga operations per second (GOPS) of DSP performance the mid-range QB4 offers 4 TOPS machine learning and 256 GOPS DSP and the range-topping QB16 manages 16 TOPS for machine learning workloads and 1 TOPS for DSP workloads.

The result, the company claims, is a simpler approach with area, power, and efficiency gains over traditional multi-core alternatives. The company's Chimera chip design does away with the distinction between NPU, CPU, and DSP, offering a single unified architecture accessible from a single software stack - supporting scalar, vector, and matrix math in one single logical processing core. The new Chimera GPNPU family creates a unified, single-core architecture for both ML inference and related conventional C++ processing of images, video, radar or other signals, eliminating multicore challenges." In an age when signal processing lies at the core of so many different technologies, nothing is more important than its contribution to health care. "The limitation of that approach is the clumsy way the programmer has to partition her code across the different cores in the system and then tune the interaction between those cores to get desired performance goals.
