DeviceWare Ltd — Embedded Electronics Design

DeviceWare is a Christchurch, New Zealand based electronics design company specialising in embedded product development. We will:

  • develop the hardware and embedded software for products;
  • design for manufacture, and can organise manufacture;
  • perform feasibility investigations and rapid proof-of-concept prototyping;
  • advise on development processes, requirements capture, configuration management, and project setup; and
  • provide mentoring and training.

Over 25 years of hands-on experience across embedded hardware, firmware, and control systems — working as a sole engineer or leading a team. No recruiting overhead, no ongoing cost once the project is complete.

T803 Radio–Telephone Interface

DSP-based product interfacing radio equipment to telephone lines — from initial design through to production, then a second enhancement pass. Fixed-point notch and bandpass IIR filters designed for numerical stability across the full signal range; guard-tone detection sensitive to −40 dBm against −20 dBm voice signals. Enhancement revision replaced AGC/Mu-law codec with a linear codec, greatly simplifying the DSP filter design, and demonstrated adaptive echo-cancellation.
