On-Device AI

The GW2120 is an artificial intelligence system on a chip (AI-SoC), with 32-bit RISC core, AI Inference Accelerator, and peripherals. The GW2120 integrates ARM® Cortex-M4F and 128 16-bit floating point (FP16) Multiply-Accumulate (MAC) logic which can operate up to 180 MHz, and vector processing manipulator for efficient neural network operations. Two high speed Quad Serial Peripheral Interface (QSPI) for serial NAND or NOR flash memory which enables access of large number of neural network coefficients in efficient way. 2,048 KB shared SRAM exists between the AI Inference Accelerator and the RISC core.
The GW2120 support digital interfaces for various sensors like SPI/I2C/I2S/UART/PWM/PDM. A 12-bit SAR ADC allows analog sensor signal input and Digital DAC allows analog audio output.
Two internal oscillators, Phase Lock Loop (PLL) circuit, and two LDOs minimize required external components for system implementation.
