Applications of the K2H and K2E platforms in

high-end imaging

performance platforms that deliver power-

imaging applications. These devices are

the ﬁrst to integrate ARM^®Cortex™-A15

The integration of the Cortex-A15 pro-

cessors greatly reduces system cost and

design complexity by removing the need for

a high-end general-purpose processor. With

full support of SMP Linux™, the Cortex-A15

processors enable developers to quickly and

easily migrate existing software designs to the

low-power, high-performance K2E and K2H

platforms.

Table 1 – Devices in the KeyStone II architecture

Many high-end imaging applications require

powerful real-time processing as well as the

need to run operating system and control

code. With the K2H platform, developers of

applications will have for the ﬁrst time, a full

ARM-based Linux device integrated with the

industry’s highest-performing DSP cores in a

single power-efﬁcient package that can deliver

up to 352 GMACS, 198 GFLOPS and 19,600

Dhrystone MIPS. Coupled with industry-best

development tools and multicore software

support for OpenMP^®and OpenCL™,

developers can easily parallelize code and run

it on the ARM or DSP cores and quickly create

code that scales across the different devices

within the K2H and K2E platforms, allowing for

the most cost- and power-efﬁcient designs.

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

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

•ꢀ Objectꢀtracking

Becauseꢀtheꢀprocessingꢀelementsꢀofꢀ

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.

TI’s KeyStone II SoCs are well equipped

toꢀhandleꢀtheꢀcombinationꢀofꢀtheꢀNVR/DVRꢀ

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 cores in the K2H platform

are ideal for running advanced analytics

algorithms. Providing both ﬁxed- and
