Abstract
A system on a chip (SoC) converts outputs from its temperature and power controllers into operating points through mapping policies set during nominal silicon characterization. Because thermal and electrical behavior shifts with workload activity, silicon process variation, and aging, a fixed mapping policy can leave thermal and power budgets underused or request operating points that press measured temperature or power toward platform limits. The disclosed system retains existing temperature and power control loops while adding a temperature impact block, a power impact block, and a performance impact block that evaluate measured SoC behavior and propose localized refinements to the mapping policies. A mapping supervisor block then arbitrates among those proposals and publishes active mapping policies. Separating resource regulation from operating-point selection improves performance utilization while holding thermal and power operation within budget.
