Vision 4DR Accelerator

Overview

Hardware Accelerator for 4D Imaging Radar Solution for Vision 331 and Vision 341 DSPs

The Cadence Tensilica Vision 4DR Accelerator is a hardware designed to address the increasing computational requirements for 4D Imaging radar for the automotive market. While working in conjunction with Vision 341 DSP, it provides up to 4X greater FFT performance than the Vision 240 DSP and 7X greater FFT performance than Vision 230. Because of its much higher performance than a DSP-only solution, a combined solution of Vision 331/341 and Vision 4DR saves considerable power and area.

Key Benefits

Hardware pipeline specifically to operate on 2D/1D 16 and 24-bit DSP

High Performance

While working in conjunction with Vision 341 DSP it provides up to 4X greater FFT performance than Vision 240 DSP and 7X greater FFT performance than Vision 230

Features

Hardware Accelerator for 4D Imaging Radar Solution for Vision 331 and Vision 341 DSPs

Vision 4DR Accelerator has been designed to provide the best combination of hardware wire and programmable solution for 4D imaging radar. It offers the ability to operate on large data cubes required for today’s automotive solution. Because of its much higher performance than a DSP-only solution, a combined solution of Vision 331/341 and Vision 4DR saves considerable power and area.
