DYNAMICALLY CONFIGURABLE ANALOG FRONTEND CIRCUITRY

摘要

An analog frontend (AFE) interface is dynamically programmable. A single AFE circuit can interface with multiple different analog devices, and dynamically configure its input for efficient interfacing with each different analog device. The AFE receives multiple unprocessed analog input signals and samples the analog input signals. A preprocessor element in the AFE analyzes the input signals and generates control signals based on the analyzing. The control signals dynamically adjust how the AFE samples the analog input signals, and can improve the efficiency of the operation the AFE.

1. A method for interfacing a digital processor with multiple analog devices, comprising:
receiving multiple unprocessed analog input signals from multiple different analog devices at a dynamically configurable frontend circuit, the frontend circuit including analog interface components and a preprocessor component; sampling the analog input signals with the frontend circuit, including analyzing the analog input signals with the preprocessor component; and sending control signals from the preprocessor component to the analog interface components based on the analyzing by the preprocessor component to dynamically adjust how the frontend circuit samples the analog input signals.
