Abstract
One or more computing devices, systems, and/or methods are provided. In an example of the techniques presented herein, a system comprises a first input terminal and a first programmable analog block configured according to a first configuration. A controller is configured to reconfigure the first programmable analog block according to a second configuration different than the first configuration based on a first signal received at the first input terminal.
Claims20
A system, comprising:
- a central processing unit;
- and
- a programmable analog sub-system connected to the central processing unit and comprising:
- a first input terminal;
- a first programmable analog block configured according to a first configuration;
- and
- a controller configured to reconfigure the first programmable analog block according to a second configuration different than the first configuration based on a first signal received at the first input terminal independent from the central processing unit.
4 more elements
A programmable analog subsystem, comprising:
- a first operational amplifier;
- first routing circuitry configured to connect the first operational amplifier to a first input terminal in a first configuration and to connect the first operational amplifier to a second input terminal in a second configuration;
- second routing circuitry configured to connect one of a first reference signal or a second reference signal to the first operational amplifier in the first configuration or the second configuration;
- and
- a controller configured to receive an output signal of the first operational amplifier in the first configuration and reconfigure the first routing circuitry or the second routing circuitry based on the output signal.
2 more elements
A method, comprising:
- configuring a first programmable analog block according to a first configuration;
- configuring a second programmable analog block according to a second configuration;
- receiving a first input signal at the first programmable analog block;
- generating a first output signal based on the first input signal received at the first programmable analog block;
- and
- reconfiguring one of the first programmable analog block or the second programmable analog block according to a third configuration based on the first output signal without intervention from an external central processing unit.
