Cadence claims 10X boost for automotive radar/lidar, 30X boost for 5G
With an enhanced instruction set architecture (ISA) and clock-speed increase, the ConnX B20 DSP processes parts of the communication processing chain up to 30X faster and parts of the radar/lidar processing chain up to 10X faster compared to the company’s Tensilica ConnX BBE32EP DSP. Software compatible with the rest of the ConnX DSP family, the ConnX B20 DSP has a 512-bit vector width up to 128 MACs, can load 1024 bits of data each cycle and achieves 1.4GHz or greater frequency in 16nm process technology. This extends the ConnX family to serve an even broader range of performance. Customers have a variety of algorithm acceleration options to reduce cycle counts, including higher precision with either 32-bit fixed-point operations (including operations to optimize MAC, FFT and FIR) with native complex support, or single-/half-precision vector floating-point (VFPU) operations with half precision at 2X the single-precision throughput. An extended VFPU option enables support for complex floating-point operations and doubles the real floating-point operations at the same vector width typically used in the front end of the radar processing chain. The communications option accelerates forward-error correction (FEC) in lower bit-rate communication applications seeking software-defined radio solutions. General availability for both the ConnX B20 is planned for the second quarter of 2019.
