Cadence Tensilica ConnX B20 DSP helps improve automotive radar/lidar performance up to 10 times, and 5G communication performance improves 30 times
Deeper pipelines and significant instruction set enhancements deliver higher performance at lower power consumption
Shanghai, China, February 28, 2019 - Cadence Electronics (Cadence, Inc., NASDAQ: CDNS) today announced the launch of Cadence® Tensilica® ConnX B20 DSP IP, which is the most powerful DSP product in the ConnX family . Based on a deeper pipeline architecture, ConnX B20 DSP provides faster and more energy-saving solutions for the automotive and 5G communication markets, including new generation radar, lidar, vehicle-to-external information exchange (V2X), user equipment (UE)/ Infrastructure and IoT applications. With a significantly enhanced instruction set architecture (ISA) and increased clock speeds, the ConnX B20 DSP can handle parts of the communications processing chain up to 30 times faster than the widely used Tensilica ConnX BBE32EP DSP, most radar/laser Radar processing chain speed increased by up to 10 times. To further expand the ConnX family, Cadence has launched the ConnX B10 DSP, which offers half the vector width of the ConnX B20 DSP for applications requiring less parallelism.
As more and more antennas are used for high-resolution imaging radar in autonomous driving applications, and with the emergence of 5G mobile devices and infrastructure, the requirements for processing power have also greatly increased. In addition, consumer/industrial radar, automotive V2X and 5G IoT applications all require low-energy processing solutions. With the addition of the ConnX B20 and B10 DSPs, the ConnX family excels in meeting the demands for higher performance and low energy consumption.
ConnX B20 DSP is fully software compatible with other products in the ConnX DSP series (ConnX BBE16/32/64EP). B20 has a 512-bit vector width, a maximum of 128 MACs, and can load 1024-bit data per cycle. The main frequency can be Reach 1.4GHz or higher frequency. This extends the ConnX family to serve a wider range of performance needs. Customers have multiple algorithm acceleration options to reduce loop counts, including support for native complex higher-precision 32-bit fixed-point operations (including optimized MAC, FFT and FIR operations), or single-precision/half-precision vector floating point (VFPU) operations ( Half precision is 2x the throughput of single precision). This flexibility allows customers to select higher precision only when needed. In addition, the extended VFPU option supports complex floating point operations and doubles the actual floating point operations at the same vector width typically used at the front end of the radar processing chain. Some low-bitrate communication applications require software-based radio solutions, and the communication option can accelerate forward error correction (FEC).
Compared with the currently popular ConnX BBE32EP DSP, the ConnX B20 DSP has optional native 32-bit support options and higher clock frequencies, which can improve the performance of most radar/lidar processing chains by 10 times. Through increased clock rates and FEC acceleration options, the ConnX B20 DSP can increase the speed of some communication processing chains by 30 times compared to the ConnX BBE32EP DSP. The ConnX B20 and B10 DSPs provide customers with increased performance and efficiency while retaining existing architecture and development environments. Customers can quickly optimize their application's power, performance and area (PPA) requirements with easy scalability and extensive configurability while being compatible with the ConnX DSP family. In addition, they can perform rapid software development using advanced compilers, debugging and simulation tools, as well as optimized math libraries and source code application examples.
"Autonomous driving requires high-resolution sensing to identify different objects at a distance. Adding more antennas can improve radar resolution, which requires a corresponding increase in DSP performance," said Mike Demler, senior analyst at Linley Group. LiDAR systems need to have high enough resolution, but are too expensive for widespread deployment today. However, new solid-state implementations are changing this as algorithms and designs mature, which also require certain DSP capabilities. programmability. The rollout of 5G infrastructure and devices will drive higher bandwidth, lower latency, and lower energy consumption for edge devices as signal power requirements decrease, and these new designs require higher performance across multiple use cases. High performance and scalability. Tensilica ConnX DSPs are already used in a variety of automotive sensor and communications applications, and the new ConnX B20 and B10 DSPs provide the level of performance and energy efficiency required for next-generation devices."
“ArrayComm has developed physical layer software for 4G LTE, CAT-M and NB IoT base stations using the Cadence Tensilica ConnX BBE32EP DSP,” said Xin Huang, president of ArrayComm. “We found the ConnX DSP to be powerful and efficient, especially in vector processing. . We look forward to working with the Tensilica team to port ArrayComm’s 5G PHY to the latest ConnX DSP.”
“Next-generation imaging radar and 5G communications are driving exponential growth in data throughput,” said Lazaar Louis, senior director of product management and marketing for the Tensilica IP Group at Cadence. "To meet the growing demand from our customers for high-performance radar and communications solutions, we continue to invest in the development of our successful ConnX DSP family. Our new ConnX B20 and B10 DSPs extend our range of scalable, compatible DSPs to higher "The higher clock speeds and more optimized instructions optimize complex digital processing, providing customers with a convenient way to upgrade existing radar and application designs in radar and communications applications across a variety of markets."
ConnX B20 and B10 DSPs are generally scheduled to be available in the second quarter of 2019. Customers interested in early access should contact Cadence.
