Validating Performance: Lab Test Results

Let’s uncover the lab test results to see how it performs in real-world conditions.

Power Consumption Analysis

The SK-AM62A demonstrates exceptional power efficiency even for an edge device.

Running a single algorithm, the board consumes approximately 2 watts with a current draw of 2.5 amps.

This value is further reduced for less demanding tasks like image classification.

Power consumption scales with algorithm complexity.

With four camera feeds, running four different algorithms simultaneously, the power consumption is around 2.5 watts while maintaining a total current level below 3 Amps.

Voltage Regulation

Voltages across various nodes of the power rail are observed to be extremely stable. The power rail structure and voltage levels are shown below:

We have measured these voltages experimentally and the result is shown below:

These results are obtained while running four camera feeds that were getting processed simultaneously and one can observe, even in this limiting scenario, the voltage levels are extremely stable maintaining a near zero voltage regulation making it ideal for edge AI applications.  

Thermal Performance

Extensive testing has confirmed the board’s excellent thermal management. In a controlled environment, running a single camera feed resulted in a minimal temperature rise of only 2°C.

Processing four feeds simultaneously increased the average temperature by 4-5°C.

With a critical trip temperature of 105°C, the SK-AM62A is well-suited for deployment in harsh outdoor environments.

Model statistics

In case of applications like automatic traffic management, realtime processing and decision making plays a key role. 

As observed from the above table, while running an image classification task, the inference time is 7.6 milliSeconds while maintaining a decent frame rate of 30 fps. This type of high speed processing is conducive to real time decision making in critical use cases like traffic management where even a one second delay may cost someone’s life. 

These specs vary from algorithm to algorithm and that can be observed from the tables below:

The lowest frame rate has been observed in case of human pose estimation and it is nearly 8.5 frames per second.

While processing all the four camera feeds together, we are getting less than 50 milliseconds of inference time and framerate of nearly 12 frames per second that can be observed from the table below.

To comprehensively evaluate performance, we conducted various benchmarking tests using industry-standard tools like LMBench, Linpack, and Stream. These tests assess various parameters including basic processor operations, floating-point computing performance, and latency. The detailed results are presented below and demonstrate the board’s well-rounded capabilities for real-time edge AI applications.
