The combination of these functions in

an industrial automation system requires

significant real-time processing. These

processing functions can be implemented in

a smart industrial imaging camera with a low-

power, high-performance processor like TI’s

TMS320C665x multicore DSPs which provide

enough processing power to do many industrial

automation functions while remaining within

the power limitations of the camera.

Where more processing is needed or post

processing analysis is desired, a multi-headed

processing unit taking input from several

cameras in a centralized vision processing

unit as part of a comprehensive industrial

automation system is deployed, as shown

in Figure 2. This central system typically is

responsible for most of the analytic processing.

The K2E and K2H SoC platforms provide

an elegant, scalable solution for this type of

centralized processing in industrial automation

systems.

With the Cortex-A15 processors in the K2H

and K2E devices and the development tools

and programming models available from TI,

developers have the ability to support full ARM-

based Linux™ systems while offloading the

real-time processing to the high-performance

C66x cores. The offloading of real-time

processing enables a more power-efficient,

high-performance centralized processing unit.

For more complex systems requiring additional

processing capacity, TI’s HyperLink can be used

to connect multiple KeyStone devices adding

additionalC66xDSPcoresand/orCortex-A15

processors.

Becausetheprocessingelementsof

the KeyStone SoCs are programmable and

scalable, the system has maximum flexibility,

allowing the same processing system to

be used across different product lines. The

scalability is further expanded because the

C66x cores in the K2H platform are the same

as those in the C665x platform. Therefore,

code developed for the C66x core that is used

in the central processing unit can migrate to

the smart automation camera and vice versa,

allowing maximum reuse and scalability.

Video Surveillance: Video surveillance appli-

cations will also benefit from TI’s K2H and K2E

platform of devices. This is particularly true in

the popular network video recorder (NVR) and

digital video recorder (DVR) hybrid, known as an

NVR/DVR,andthestandaloneanalyticsservers.

These end equipments get their video

content through a network connection and

mayhavetoencode/transcodethevideo

before storing it. Video can then be retrieved,

decoded/transcodedwhennecessary,and

have various analytics algorithms run on all or

parts of the video stream. Common analytic

algorithms used in surveillance are:

• Tamperdetection

• Motiondetection

• Tripzone/boundarycrossing

• Objectdetection/removal

• Objectidentification

• Objectcounting

• Objecttracking

• Behavioranalysis

• Facialrecognition

• Licenseplaterecognition

TI’s KeyStone II SoCs are well equipped

tohandlethecombinationoftheNVR/DVR

functionality and the need for processing the

analytics algorithms listed above.

KeyStone II devices feature a network

coprocessor AccelerationPac. This

AccelerationPac consists of a packet

accelerator and a security accelerator that

work in tandem to offload the DSP and

ARM cores. This enables high-performance

network application processing while freeing

the C66x DSP and Cortex-A15 processors for

otherfunctionslikeanalytics,videoencode/

decode, running the operating system (OS)
