Core voltage reset systems and methods with wide noise margin

摘要

Presented systems and methods facilitate efficient reset operation. In one embodiment, a system comprises a core domain portion an I/O domain portion and a core reset I/O by-pass component. The core domain portion is configured to operate at a nominal core domain voltage level. The I/O domain portion configured to operate at a nominal I/O domain voltage level. The core reset I/O by-pass component configured to forward a reset indication to the core domain independent of the I/O domain. In one exemplary implementation the core reset I/O by-pass component is operable to receive an input reset indication at a high domain voltage level and to convert the input reset indication to a core reset signal that is less than or substantially equal to the nominal core domain voltage, wherein the high domain is voltage higher than the core domain voltage level.

1. A system comprising:
a core domain portion configured to operate at a nominal core domain voltage level; an I/O domain portion configured to operate at a nominal I/O domain voltage level that is different from said nominal core domain voltage level; and a core reset I/O by-pass component configured to forward a reset indication to the core domain portion independent of the I/O domain portion.
