XMOS XU316 HiFi Decoder ZeroCode Solution

Solution Overview

The XMOS XU316, with its unique multi-core architecture and software-defined interfaces, delivers nanosecond-level ultra-low latency performance and handles multiple digital audio interfaces and protocols simultaneously, establishing its leadership in high-end USB HiFi decoder applications. However, this powerful multi-core architecture also introduces significant software development complexity, presenting substantial technical barriers for customers and extending product development and time-to-market cycles.

To address this challenge, Phaten has developed the XMOS XU316 USB HiFi Decoder ZeroCode Solution, enabling rapid product deployment and dramatically reducing time-to-market.

System Architecture

The system architecture diagram above illustrates our solution, centered around the XMOS XU316 processor with ZeroCode firmware, communicating with MCU via UART.

The system supports multiple inputs (USB/SPDIF/I2S) and outputs (SPDIF/I2S), offering flexible integration with DAC chips.

The MCU customizes the ZeroCode firmware through UART configuration and manages LCD display, key inputs, and LED indicators, allowing customers to focus exclusively on product differentiation.
