Introduction

In this article, we will explore the latest sensor subsystem and integrated hardware and software solution offered by Schnapps Systems. As sensors become increasingly prevalent in our daily lives and various applications rely on their ability to interpret environmental conditions, this comprehensive subsystem aims to provide a Simplified and efficient approach to sensor-based control applications.

The Growing Importance of Sensors

Sensors have become an essential part of our modern world, with their presence in numerous industries and applications such as automotive, mobile devices, and the Internet of Things (IoT). They enable us to Gather valuable data and interpret environmental conditions, including pressure, temperature, motion, and proximity. As the demand for sensor-driven functionalities continues to grow, the need for integrated and pre-verified sensor solutions becomes crucial.

Overview of the Sensor Subsystem

At the core of the sensor subsystem lies a power and area-efficient design featuring the ARC EM4 32-bit processor. This highly configurable processor allows designers to implement custom instructions tailored to their specific application requirements. The subsystem includes GPIO, Serial Peripheral Interface (SPI), and Inter-Integrated Circuit (I2C) digital interfaces, facilitating off-chip sensor connections and seamless integration into full systems.

Integrated Hardware Solution

The sensor subsystem incorporates low-power and high-resolution analog-to-digital converters (ADCs) that efficiently digitize analog sensor data for processing. Additionally, hardware accelerators are included to boost system efficiency by implementing various sensor data processing functions. With a rich library of digital signal processing (DSP) functions and peripheral software drivers, the sensor subsystem significantly accelerates sensor application code development.

ARC EM4 Processor

The ARC EM4 processor is a key component of the sensor subsystem, delivering exceptional configurability. Designers can implement custom instructions tailored to their application's needs, allowing for optimized performance and efficiency. This flexibility enables a fine balance between hardware performance and software flexibility, streamlining the overall integration process.

Digital Interfaces for Sensor Connections

To enable seamless sensor connections, the sensor subsystem provides GPIO, SPI, and I2C digital interfaces. These interfaces facilitate the integration of off-chip sensors and ensure smooth data transfer between the sensors and the ARC EM4 processor. The flexibility of these interfaces enables designers to accommodate various sensor types, enhancing the subsystem's versatility.

Peripheral Software and Drivers

To expedite the integration of I/O peripherals with the ARC EM4 processor, the sensor subsystem offers a comprehensive range of peripheral software drivers. These drivers simplify the interface between the subsystem and the host or application processor. By alleviating integration trade-offs between hardware performance and software flexibility, the sensor subsystem enables designers to focus on optimizing application-specific functionalities.

Configurable DSP Accelerators

The sensor subsystem incorporates more than 10 configurable DSP accelerators, which significantly reduce memory footprint and power consumption. By implementing the comparable software functions in hardware, these accelerators offer a 10x decrease in power consumption compared to discrete component implementations. A user-friendly configuration tool and sensor-specific architectural templates further expedite the customization process, allowing designers to configure a complete sensor subsystem in a matter of hours.

FPGA Prototyping for Software Development

Schnapps Systems provides an FPGA-based prototyping solution that enables immediate software development and serves as a scalable platform for rapid system integration and validation. This prototyping solution allows designers to validate the functionality of the sensor subsystem efficiently and identify potential optimization opportunities. It offers a cost-effective approach to evaluating the system's performance before moving on to full-Scale production.

SOC Integration and Customization

For seamless SOC integration, Schnapps Systems offers SOC integration services to assist customers in integrating the subsystem into their chip or customizing it to meet their unique application requirements. These services ensure that the sensor subsystem aligns seamlessly with the overall system architecture, minimizing compatibility issues and optimizing overall performance.

Conclusion

In conclusion, the Sensor Subsystem provided by Schnapps Systems offers a comprehensive solution for integrating sensor functionalities into SOC designs. By providing pre-integrated and pre-verified hardware and software components, designers can significantly reduce design effort, lower design risk, and accelerate time to market. The configurability of the ARC EM4 processor, combined with the rich library of DSP functions and peripheral software drivers, ensures flexibility and customization for diverse sensor applications.
