Speed without the expense

چکیده
Speed without the expense The answer lies in the very nature of embedded systems, which are often manufactured by the thousands or even millions of units. Even a one dollar reduction in per-unit hardware costs can save the manufacturer a small fortune. Many of these systems are cost sensitive, where the use of multi-gigahertz processors or a large memory array is not possible. In the automotive telematics and infotainment market, for instance, the typical 32-bit processor runs at about 200 MHz – a far cry from the 2 GHz or faster processors now common in desktops and servers. In an environment like this, an RTOS designed to extract extremely fast (and predictable) response times from lower-end hardware offers a serious economic advantage.

Adaptation to temporal modulation can enhance differential speed sensitivity
During adaptation to a moving pattern, perceived speed decreases. Thus we know that the adapted visual system does not simply code the absolute speed of a stimulus. We hypothesised that adaptation to a moving stimulus serves to optimise coding of changes in speed at the expense of maintaining an accurate representation of absolute speed. In this case we would expect discrimination of speeds aro...
