SENSORY PROCESSING SOLUTIONS

GTronix is destined to be the sensory-processing solution-of-choice for a wide variety of sensory processing applications by leveraging the key advantages of the APT Technology:

Integration of the entire sensory processing chain into a single IC - GTronix analog VLSI solutions absorb not only the sensory signal processing from the DSP, but also incorporate the analog interface to the sensor and signal conditioning (e.g. filtering). A/D conversion is an option for designs requiring a digital output. Because all information extraction occurs prior to sampling by the A/D, the sampling requirements are dramatically reduced, resulting in power and cost savings.

Significantly smaller form factor than digital alternatives - The core signal processing function (a multiplier), requires 3600 digital gates where the APT Technology floating gate version requires only 4 transistors! This 900X reduction translates to much more compact (and cost-effective) implementations. APT Technology signal processing functions typically dwarf their digital counterparts when it comes to size.

Power reduction by orders of magnitude - APT Technology circuits operate in sub-threshold, significantly lowering power consumption. For example, a DSP-based 64 point FFT consumes 520 mW; GTronix's implementation requires only 13 mW - 40X advantage.

Low-latency, real-time continuous processing - The traditional sample-store-process approach in digital signal processing necessarily introduces latency into the system design. High latencies are unacceptable in most real-time applications. GTronix's low-power, low-latency solution is continuous and "always on."

Reduced software complexity - APT Technology solutions offload and can often completely eliminate the system DSP. By performing information extraction near the sensor, programming of the associated host processor is simplified.
