Abstract

General-purpose control information is transmitted in a serial stream between digital processors.

Description

technical field [0001] The present invention relates to a method and apparatus for transferring general control information between processors. Background technique [0002] General purpose input / output (GPIO) are signals that can be used to provide various control functions between digital processors. For example, GPIO can be used to pass interrupts between processors. Many other interprocessor control functions can also be performed using GPIO. Typically, a single GPIO contains a single bit of information, although multi-bit GPIOs can also be used. In the past, dedicated terminals (eg, leads on the processor package, bond pads on the die carrying the processor, etc.) were provided on the processor for GPIO communication to other processors. The dedicated terminal associated with a particular GPIO is then connected to a corresponding terminal on another processor via a dedicated signal line. However, as the number of GPIOs between processors grows, the use of dedicated ...
