Signaloid Compute Modules

The Signaloid UxHw® hardware family brings Signaloid’s distribution-extended compute hardware (UxHw) technology to local and on-premises deployments. Applications can run over the integrated Signaloid System-on-Chip processor where data can be probability distributions. The processor performs arithmetic on these distributions as it executes the programs, and detects correlations as they occur.

The compute modules plug into microSD or SD card slots, enabling deployment of UxHw without requiring a redesign of the host circuit board. Every module is a UxHw coprocessor that the host can access through the shared MMIO interfacing model. Each module has its own memory map, capabilities, and performance.

This section documents UxHw running locally on a hardware-module Signaloid SoC. UxHw can also run in the cloud using the Developer Platform and the Compute Engine API.

C0 Compute Modules family overview​

Each compute module caters to different form factor, host interface, and performance requirements.
