A novel fully integrated dynamic thermal management circuit for system-on-chip design is proposed. Instead of worst-case thermal management used in conventional systems, this design yields continual monitoring of thermal activity and reacts to specified conditions. With the above system, we are able to incorporate on-chip power/speed modulation and integrated multi-stage fan controllers, which allows us to achieve nominal power dissipation and ensure operation within specification. Both architecture and circuitry are optimized for modern system-on-chip designs. This design yields intricate control and optimal management with little system overhead and minimum hardware requirements, as well as provides the flexibility to support different thermal management algorithms.
