Abstract

Converting telemetry values into common data formats in a processor-based system in an integrated circuit (IC) chip is disclosed herein. In one aspect, an IC chip comprises a processor-based system that that is configured to receive an input telemetry value from an input source circuit. The processor-based system converts the input telemetry value into a common format telemetry value, wherein a first unit value represented by a least significant bit of the common format telemetry value is greater than one (1) and is based on a quotient of a power of two (2) and a corresponding power of 10. The processor-based system then processes common format telemetry value.
