“Efficient integration of dedicated IP has become increasingly critical to meet the sensor processing requirements of IoT solutions,” said Chuck Gritton, chief technology officer at Hillcrest Labs. “Synopsys has created a compelling IP subsystem that helps designers create more power-, area-, and performance-efficient sensor processing solutions for IoT devices.”

The DesignWare Sensor and Control IP Subsystem is designed to process data from digital and analog sensors and always-on audio sources with minimal power consumption. This enables offloading of the host processor and more efficient processing of the data.

 The fully configurable subsystem includes the choice of an ARC EM4, EM6, EM5D or EM7D processor. All the processors support up to 2MB of closely coupled memory (CCM) for both instruction and data, while the EM6 and EM7Dalso incorporate up to 32KB of instruction and data cache for maximum system performance and flexibility.

The EM5D and EM7D combine high-efficiency control and signal processing with more than 100 DSP instructions. The subsystem’s integrated UART, PWM and ARM® AMBA® APB™ interface peripherals combined with the configurable GPIO, SPI, I²C and ADC/DAC interfaces offer a wide range of off-chip sensor and actuator connections.

The DesignWare Sensor and Control IP Subsystem is optimized to process the extensive amount of data in sensor fusion applications. The subsystem includes a rich library of off-the-shelf DSP functions supporting filtering, correlation, matrix/vector, decimation/interpolation and complex math operations.
