A deeper, 13-stage processor pipeline and system architecture designed for use with large local memories enable the Tensilica Vision Q7 DSP to achieve 1.5GHz peak frequency. As a result, designers using the Vision Q7 DSP can develop high-performance products that meet increasing vision and AI demands and power-efficiency needs.
The Vision Q7 DSP is specifically optimized for simultaneous localization and mapping (SLAM), a technique commonly used in the robotics, drone, mobile, and automotive markets to automatically construct or update a map of an unknown environment, and in the AR/VR market for inside-out tracking. The Vision Q7 DSP delivers up to 1.82 tera operations per second (TOPS), 1.7X higher TOPS compared to the Vision Q6 DSP in the same area. To address the increasing computational requirements for embedded vision and AI applications, the sixth-generation Vision Q7 DSP provides up to 2X greater AI and floating-point performance in the same area compared to its predecessor, the Vision Q6 DSP.
◾An enhanced instruction set supporting 8/16/32-bit data types and optional VFPU support for single- and half-precision enables up to 2X faster performance on SLAM kernels compared to the Vision Q6 and Vision P6 DSPs
◾Delivers up to 2X improvement in floating-point operations per mm2(FLOPS/mm2) for both single-precision (FP32) and half-precision (FP16) compared to the Vision Q6 and Vision P6 DSPs
◾Up to 2X greater AI performance in the same area compared to the Vision Q6 DSP results in up to 2X improvement in GMAC/mm2compared to the Vision Q6 DSP
◾Support for on-the-fly decompression of weights
For AI applications, the Vision Q7 DSP provides a flexible solution delivering 512 8-bit MACs, compared to 256 MACs for the Vision Q6 DSP. For greater AI performance, the Vision Q7 DSP can be paired with the Tensilica DNA 100 processor. In addition to computational performance, the Vision Q7 DSP boasts a number of iDMA enhancements including 3D DMA, compression, and a 256-bit AXI interface. The Vision Q7 DSP is a superset of the Vision Q6 DSP, which preserves customers’ existing software investment and enables an easy migration from the Vision Q6 or Vision P6 DSPs.
