1   Abstract

Data aggregation communication in battery-powered, space-constrained environments poses unique challenges, particularly in systems where multiple devices need synchronization. GOWIN's GW1NZ FPGA devices present an innovative solution, offering ultra-low power consumption, compact form factors, and versatile capabilities for seamless data aggregation. This white paper explores the features, applications, and advantages of GW1NZ FPGA devices in addressing these challenges.

2   Introduction

Numerous applications are in sync with multiple sensors spread across two or more subsystems. Each subsystem is usually an individual board. These sensor’s data need to be collected and added to the base system or main SOC. At the same time, the base system or main SOC needs to send commands or set parameters to these subsystems. These usually utilize low-speed protocols such as I2C, UART, SPI, etc and work as sideband communication channels in the system. The traditional method is simply following the protocol and results in many wires being used between the base system and subsystems.

Data aggregation refers to the process of combining information from various sources, thereby minimizing the need for numerous physical network connections between two communicating systems. Aggregate data is high-level data that is acquired by combining individual-level data. Combining the low-speed data and sending the aggregate data through a high-speed channel, can effectively reduce the number of wires between the base system and subsystems. It also reduces redundant data and helps lower the system's power consumption. One good example is the OCP DC-SCM project in server applications.

In scenarios demanding data aggregation under battery operation within limited spaces, conventional solutions often struggle due to power constraints and space limitations. These applications encompass a range of devices, including wearables and portables such as AR/VR devices, Smart Glasses, Cell phones, and more. GOWIN's GW1NZ FPGA devices stand out as a pioneering solution, surmounting these challenges with their distinctive features and capabilities.
