A high level language implementation of a general purpose telemetry system for biomedical applications

This paper describes a general purpose biomedical telemetry system consisting of an implantable VLSI chip and an RS232 compatible remote telemetry receiver. The implant supports a variety of programmable options to provide compatibility with a number of commercially available sensors. Additional hardware is included for the variation of sample rates and their occurrence to allow support for sensors of various speed. Also included is the capability to store samples in an internal static RAM, allowing the biological host to operate in its own environment without the need for an external monitor. Covered is the architecture of the proposed telemetry system, methods of implementation through HDL and comparative results obtained from these implementations.
