TI strengthens DSP and vision processing on its "Jacinto" family of infotainment processors

DETROIT, USA: Texas Instruments (TI) is adding signal processing functionality to its new DRA75x processors to enable customers to augment infotainment and pair informational advanced driver assistance systems (ADAS) features.

The combination of these two will allow customers to produce cars with digital cockpit integration as well as traditional infotainment features without compromising performance. The new DRA75x processors, "Jacinto 6 EP" and "Jacinto 6 Ex", both developed on the same architecture as other "Jacinto" devices, enable automotive manufacturers to scale their investment without additional R&D or significant Bill-of-Material (BOM) increase to deliver a diverse portfolio of products with hardware and software compatibility.

"Jacinto 6 EP" is a processing leader in the infotainment segment with 1.4GHz of digital signal processor (DSP) performance equivalent to 22 GFLOPS / 60 GMACS. Complete with all the features of the "Jacinto 6", the "Jacinto 6 EP" device provides additional peripherals and DSP horsepower to add features while controlling system cost.

"Jacinto 6 EP" lowers the BOM by incorporating additional USB, video input and PCIe interfaces required in certain infotainment systems with demanding IO requirements. A second TMS320C66x DSP core, delivering a total of 1.4 GHz of signal processing, can be used for image manipulation technologies such as dynamically stitching multiple cameras into a single, surround or overhead view.

Also, the additional DSP performance enables augmented radio configurations (multi-tuner, multi-modal configurations leveraging antenna diversity and background scanning), audio and speech processing, active noise control (ANC), voice recognition and a variety of other technologies.

Further scaling the platform, the "Jacinto 6 Ex" device provides additional performance and integration possibilities from the "Jacinto 6 EP" by offering two embedded vision engines (EVEs) for simultaneous informational ADAS and infotainment functionalities without compromising the performance of either system.

Informational ADAS describes capabilities such as object and pedestrian detection, augmented reality navigation and driver identification leveraging cameras both inside and outside the car to enhance the driving experience without actively controlling the vehicle. These capabilities can be leveraged in the center stack, programmable cluster and head's-up display systems.

The EVEs enable high-performance analytic and vision algorithms operating concurrently with the ARM®, GPU, DSP, multimedia and additional sub-systems offering un-encumbered performance unlike anything available on the market today. Both EVEs and associated software libraries put customers in control of their development by leveraging the flexible, programmable, high-performance EVE cores for analytics algorithms.
