Software-Compatible DSPs For Radar, Lidar and 5G Applications

The Cadence®Tensilica®ConnX family of enhanced digital signal processors (DSPs) establishes a new standard in high-performance, low-power digital signal processing specifically designed for radar, lidar, and communications processing. Optimized for complex number processing, the ConnX DSPs offer a wide range of software-compatible power, performance, and area (PPA) points to suit the needs of any application. These DSPs provide the scalability needed to deliver energy-efficient programmable solutions for radar, lidar, and communications applications (such as infrastructure, user equipment, IoT, and V2X). Easily optimized through check-box options, the ConnX DSPs provide unprecedented flexibility in implementing systems at power-consumption levels that significantly reduce the need for hardware accelerators. There are five members of this DSP family: BBE16EP, BBE32EP, BBE64EP, B10, and B20.
