Urgent and important automotive tasks require fast reactions and smart thinking

Urgent and important automotive tasks require fast reactions and smart thinking

"What is important is seldom urgent, and what is urgent is seldom important." - wise words indeed from Dwight D. Eisenhower - the 34th president of the United States of America. In so many aspects of life this is true and as a maxim it can allow us to manage our time more effectively. However, back in the late 1950's when Eisenhower made this statement, the Aston Martin DB4 was state-of-the art and no-one could have predicted the advances in automotive technology in the next 50 years.

One of the most important tasks for a driver is to look out for hazards, especially those in their path – for instance a small child chasing a ball, completely oblivious to the oncoming vehicle. You would never consider changing the radio station before braking hard or taking avoiding action - this is truly an important and urgent situation.

As advanced image recognition systems begin to appear in vehicles the same principles apply. That’s why Toshiba’s fourth-generation image-recognition processors contain multiple accelerators including affine transform, filters and histogram, as well as multiple camera inputs – to deliver devices that yield significant increases in simultaneous-processing capability and execution speed.

The accelerators are crucial to ensuring very high-performance processing as needed by advanced ADAS functions such as pedestrian detection. Toshiba’s Co-occurrence Histogram of Oriented Gradients (CoHOG) algorithm for human detection was completed over 50 times faster in a second-generation image-recognition processor, compared to a conventional processor running at 1GHz. The execution time of 79.3ms enabled real-time pedestrian detection. The fourth-generation architecture, which benefits from the latest improved accelerators, is capable of completing the algorithm in 49.8ms, which represents a further acceleration of around 1.5 times.
