The fundamentals of GAP, the IoT application processors

Enables AI and DSP applications on battery-powered devices

GAP processors bring entirely new levels of computing capability into the realm of MCU-class energy consumption. GAP8 and GAP9 power new types of devices that combine ultra-low power consumption with sophisticated signal processing and neural network algorithms.

Flexible and programmable

The GAP RISC-V based processors are fully programmable in C/C++ giving you the ability to optimize the latest algorithms. The GAP SDK includes all the tools necessary to speed application development including a fully automated neural network toolchain from Google Tensorflow. The unique GAP AutoTiler code generator automatically optimizes the flow of data across the chip.

Dynamically adapts power consumption to the needs of the application

GAP processors incorporate dynamic voltage and frequency scaling and automatic clock gating keeping awake only the elements of the component necessary to service the current workload. Low standby power consumption and ultra-fast wake-up and power state transitions minimize energy usage across sleep, acquisition, processing, and communication states.

*FC (Fabric Controller) is the main system controller and resembles a standard MCU; it can delegate compute-intensive tasks to the Cluster.

**GAP includes a multicore compute cluster with a shared memory architecture and hardware thread synchronization. The cluster enables highly efficient, parallel implementation of algorithms giving almost optimal linear speedup.

*** 64 bit support included in selected instructions.


GAP8 allows industrial and consumer product manufacturers to integrate signal processing, artificial intelligence and advanced classification into new classes of battery-operated wireless edge devices for IoT applications including counting people and objects, human detection, head pose detection, sound analysis, face identification, speech recognition, activity classification, etc.
