CADENCE Q8 EXPANDS VISION DSPS: Vision Q8 Targets High-End Inference; P1 Handles Smart Sensors

摘要

Cadence's new Tensilica Vision DSP cores extend its intellectual-property (IP) lineup at the high end to target 3D computer vision and at the low end to reduce area and power in always-on smart sensors. The company disclosed details of its new Vision Q8 and P1 at the recent Linley Spring Processor Conference. The Q8 integrates up to 1,024 INT8 multiply-accumulate (MAC) units, and it's available for licensing now. The P1 has up to 128 INT8 units and is scheduled to begin general licensing by the end of this quarter. Figure 1 shows the range of peak AI throughput in the P- and Q-series. The Q8 targets augmented/virtual reality (AR/VR), automotive, mobile phones, and similar high-performance computer-vision systems. Running at 1.OGHz, its 1,024-unit MAC array can deliver 2,048 billion operations per second (GOPS). Cadence also offers the DSP in dual- and quad-core configurations, along with its proprietary multicore interconnect, an L2 cache, and an AXI4 system interface.
