A multiple processor architecture with flexible external input/output interface is provided. In one embodiment, an open flexible processor architecture avionics device comprises: a multiple processor architecture having a primary processor, a secondary processor, a random access memory (RAM) coupled to at least the secondary processor, and a shared memory coupled to the primary and secondary processor; and a flexible input/output (I/O) interface coupled to the multiple processor architecture, wherein the flexible I/O interface provides I/O access to the primary processor using a fixed I/O protocol, and provides I/O access to the secondary processor using at least one re-configurable I/O protocol; wherein the primary processor is dedicated to executing embedded software for implementing a primary base functionality, the primary processor has read and write access to the shared memory, and the primary processor is not reprogrammable; and wherein the secondary processor has read-only access to the shared memory and is programmable.

Systems and methods for improving MEMS gyroscope start time are provided. In one embodiment, a circuit board for a MEMS gyroscope system comprises: a proof mass assembly; a proof mass control loop coupled to the proof mass assembly by a first proof mass motion sensor pickup line and a second proof mass motion sensor pickup line, where the proof mass control loop generates a set of drive signals that operate the proof mass assembly using a first capacitive signal from the first proof mass motion sensor pickup line and a second capacitive signal from the second proof mass motion sensor pickup line; and a tunable capacitive coupler connected to at least one of the first or the second proof mass motion sensor pickup lines, where the tunable capacitive coupler varies at least one of the first and second charge signals as a function of the drive signals.
