Embedded instrumentation architecture

摘要

The various technologies presented herein relate to generating copies of an incoming signal, wherein each copy of the signal can undergo different processing to facilitate control of bandwidth demands during communication of one or more signals relating to the incoming signal. A signal sharing component can be utilized to share copies of the incoming signal between a plurality of circuits/components which can include a first A/D converter, a second A/D converter, and a comparator component. The first A/D converter can operate at a low sampling rate and accordingly generates, and continuously transmits, a signal having a low bandwidth requirement. The second A/D converter can operate at a high sampling rate and hence generates a signal having a high bandwidth requirement. Transmission of a signal from the second A/D converter can be controlled by a signaling event (e.g., a signal pulse) being determined to have occurred by the comparator component.

1. An integrated circuit comprising:
a first analog to digital (A/D) converter; a second A/D converter; and a signal sharing component, the signal sharing component comprising:
an input pin;a first output pin communicatively coupled to the first A/D converter; anda second output pin communicatively coupled to the second A/D converter, wherein the signal sharing component:receives a process signal on the input pin; anddirects the process signal to each of the first output pin and the second output pin, such that a first sample of the process signal is received by the first A/D converter and a second sample of the process signal is received by the second A/D converter, the first A/D converter processes the first sample of the process signal at a first sampling rate to form a first converted signal, the second A/D converter processes the second sample of the process signal at a second sampling rate to form a second converted signal, and the first sampling rate is lower than the second sampling rate.
