DSP core for radar, lidar and comms processing
Cadence Design Systems has launched two digital signal processing cores for embedded processing in the automotive, consumer and industrial markets.
The Tensilica ConnX 110 and ConnX 120 DSPs share a common instruction set architecture (ISA) with the high-performance ConnX B10 and B20 DSPs, offering customers such as NXP and Indie Semiconductor greater design flexibility. Together, these four DSPs cover a broad performance range from the low to the ultra-high-end, delivering scalable best-in-class, power, performance and area (PPA).
The 128-bit ConnX 110 DSP and 256-bit ConnX 120 DSP feature an N-way programming model and are fully compatible with the ConnX B10 and B20 DSPs, preserving software compatibility for easy migration. The instruction set is optimized for radar, lidar and communications applications, with optional acceleration operations for linear-feedback shift, convolutional encoding, single peak search and dual peak search. The ConnX 120 also adds Viterbi and Turbo decoders.

Like the rest of the Tensilica DSP portfolio, the ConnX 110 and ConnX 120 DSPs support the Tensilica Instruction Extension (TIE) language, which allows customers to tailor the instruction set, add specialized data types, and implement tightly integrated interfaces between the DSP and external logic. The new DSP cores are also supported by 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 to ASIL-B.
“NXP continues to rely on the Cadence Tensilica DSP cores for our ADAS product offerings,” said Robert Dunnigan, director program management ADAS at NXP Semiconductors. “We have several generations of radar products covering applications from simple corner radar to advanced front end and 4D imaging radar solutions that all utilize these DSP cores. We are looking forward to the advancements in feature set and performance improvements that the ConnX family of products will bring, as well as the continued focus on Automotive ASIL-B/D support as well as ISO 26262 compliance that Cadence provides with their DSP offerings.”
“indie is committed to developing multiple sensor modalities to enable safer vehicles in the pursuit of the uncrashable car,” said Lionel Federspiel, executive vice president of engineering for indie Semiconductor. “Cadence’s Tensilica ConnX processor family in conjunction with indie’s architecture is ideally suited to implement unique design solutions with high performance, low power, and gate count optimization. As a pure-play automotive solutions innovator, quality and reliability are essential to the success of our products.”
“Radar and communications processing trends require solutions that perform more processing in less time,” said David Glasco, vice president of research and development for Tensilica IP at Cadence. “Automotive radar demands multi-antenna, high-resolution systems with rapid response. Similarly, 5G wireless communications requires much higher data rates and lower latencies than previous generations. The Tensilica ConnX 110 and ConnX 120 DSPs meet these demands by extending the already-efficient processing capability of the ConnX DSPs and enhancing them with even more fixed- and floating-point complex data processing capacity at low power and area.”
