[0015] Power consumption concerns for processing real-time sensor data

[0016] When the main processor of an electronic device is processing many streams of real-time sensor data, the main processor consumes a large amount of power, and available resources will be taken away from other processes on the main processor. Many modern electronic devices have limited power resources (eg, due to batteries), or even when these electronic devices are plugged in, the power requirements of the power supply device during sleep or standby mode can be very stringent for power efficiency reasons. At the same time, applications are often “always on,” especially applications that are always sensing the environment or the state of an electronic device. These applications often require a host processor to continuously process real-time data from these sensors.

[0017] This computing architecture has many inefficiencies. One inefficiency is the load and storage aspect of collecting sensor d...

Abstract

A scaled and configurable pre-processor array can allow minimal digital activity while maintaining hard real time performance. The pre-processor array is specially designed to process real-time sensor data. The interconnected processing units of the array can drastically reduce context swaps, memory accesses, main processor input / output accesses, and real time event management overhead.
