A Full‑Digital Audio Solution for Creating Diverse Audio Devices Through Software
CRI SOLIDAS enables a wide range of audio devices on a single chip by implementing software‑based audio signal processing on general‑purpose MCUs / FPGAs. Feature 1: Low‑Code Development Audio systems can be developed using an audio system development package, enabling low‑code development. - Standardization: By defining design assets in software, standardization and easy reuse of design know‑how are achieved. - High Flexibility: Using dedicated tools, multiple product variations and component changes can be handled easily on a single hardware platform. Feature 2: Reduced Component Count Audio processing and audio output functions are implemented in software on a general‑purpose MCU, significantly reducing the number of components. - Multi‑Channel Support: Multiple audio output channels can be implemented using standard MCU ports. - Risk Reduction: A configuration with fewer general‑purpose components reduces procurement and inventory risks. Feature 3: High‑Performance Audio Output An original audio output mechanism, CRI D‑Amp Driver, enables high‑quality audio output with low power consumption. - High Audio Quality: Fully digital output to the speaker reduces factors that cause audio quality degradation. - Low Power Consumption: Achieves approximately half the power consumption compared to conventional amplifiers.

basic information
1. Development Environment & Design Method (Feature 1: Low‑Code Development) GUI‑based design using the audio system development package SOLIDAS Suite Audio product UI behavior and acoustic design can be visually defined Product design (logical model) and platform development (physical model) are designed separately Plug‑in architecture supports the addition of new DSP functions and custom processing Logical verification can be performed from the planning stage, improving development efficiency and supporting technology transfer. 2. System Configuration (Feature 2: Reduced Component Count) Simple system configuration centered on general‑purpose MCUs / FPGAs Multi‑channel audio output supported on a single chip Eliminates dedicated ICs and complex analog circuits, enabling a design with minimal general‑purpose components Flexible support for multiple product variations and component changes on a single hardware platform Reducing the number of components simplifies design and lowers procurement and inventory risks. 3. Audio Output Characteristics (Feature 3: High‑Performance Audio Output) Fully digital audio signal output directly to the speaker High‑efficiency output using the proprietary CRI D‑Amp Driver Low power consumption and low heat generation High audio quality and low power consumption are achieved simultaneously, making the solution suitable for a wide range of audio devices.
