New DSPs Tensilica ConnX 110 and ConnX 120 offer optimal PPA and more flexible calculation options

Cadence Design Systems, Inc. (Nasdaq: CDNS) today expanded its popular Tensilica® ConnX family of radar, lidar and communications DSPs with the launch of two new IP DSP cores for on-board processing in the automotive, consumer and industrial markets. The small Cadence with low consumption® The Tensilica ConnX 110 and ConnX 120 DSPs share a common instruction set architecture (ISA) with the proven high-performance ConnX B10 and B20 DSPs, providing customers with even greater design flexibility. Together, these four DSPs span a wide performance range from low-end to ultra-high-end, delivering best-in-class scalables in power, performance, and surface area (PPA).

The ConnX 110 128-bit DSP and the ConnX 120 256-bit DSP feature an N-way programming model and are fully compatible with the ConnX B10 and B20 DSPs, preserving software compatibility for easy migration. Like the rest of the Tensilica DSP line, the ConnX 110 and ConnX 120 DSPs support the Tensilica Instruction Extension (TIE) language, which allows customers to customize the instruction set, add specialized data types, and implement tightly integrated interfaces between the DSP and external interfaces. logic. Additionally, the new DSPs are supported by a full set of complex math library functions in the NatureDSP, Eigen, and Radar libraries. All ConnX DSPs are automotive ready with full ISO 26262 compliance to ASIL-D with FlexLock or ASIL-B.

The Tensilica ConnX 110 and 120 DSPs offer the following features and capabilities:

  • Instruction set optimized for radar, lidar and communication applications
  • 128-bit (ConnX 110) and 256-bit (ConnX 120) SIMD performance for complex mathematical operations based on 8-, 16-, and 32-bit fixed-point and half-, standard-, and double-precision floating-point
  • Common instruction set and simplified programming model, allowing code to be written once and used across different SIMD widths within the ConnX family
  • Architecture optimized for low memory footprint and low power signal processing
  • Optional easing operations for linear feedback shift, convolutional coding, single peak search and dual peak search
  • The ConnX 120 additionally offers Viterbi and Turbo decoders

“NXP continues to rely on Cadence Tensilica DSP cores for our ADAS product offerings,” said Robert Dunnigan, Director of ADAS Program Management at NXP® Semiconductors. “We have several generations of radar products covering applications ranging from simple corner radar to advanced forward-looking radar and 4D imaging solutions that all use these DSP cores. We look forward to the feature set advancements and performance enhancements that the ConnX product family will bring, as well as the continued focus on automotive ASIL-B/D support as well as ISO 26262 compliance that Cadence provides with its DSP offers. ”

“Indie is committed to developing multiple sensor modalities to enable safer vehicles in pursuit of the unbreakable car,” said Lionel Federspiel, executive vice president of engineering at indie Semiconductor. Cadence’s ConnX, combined with Indie’s architecture, is ideal for implementing unique design solutions with high performance, low power consumption and gate count optimization. pure-play automobiles, quality and reliability are essential to the success of our products.”

“Radar and communications processing trends require solutions that do more processing in less time,” said David Glasco, vice president of research and development for Tensilica IP at Cadence. high-resolution multi-antenna systems with fast response. Similarly, 5G wireless communications require much higher data rates and lower latencies than previous generations. The Tensilica ConnX 110 and ConnX 120 DSPs meet these requirements by extending the already efficient processing capability of the ConnX DSPs and enhancing them with even more capability to process complex fixed and floating point data at low power and area.”
