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.
