Abstract

A computer-implemented method, data processing system, and processor for thermal regulation control with minimal impact on interrupt latency are provided. Monitors the setting of the interrupt status bit. In response to setting the interrupt status bit, it is determined whether the interrupt associated with the interrupt status bit is an unmasked interrupt. In response to an unmasked interrupt, the existing regulation mode is disabled and the interrupt is processed, wherein the interrupt latency of the integrated circuit is reduced. Monitors the clearing of the interrupt status bits. In response to clearing the interrupt status bit, the existing regulation mode is enabled.

Description

technical field [0001] This application relates generally to the use of thermal management. More particularly, the present application relates to a computer-implemented method, data processing system, and processor for thermal throttling control with minimal impact on interrupt latency. Background technique [0002] The first generation heterogeneous Cell Broadband Engine TM (BE) processor is a 64-bit Power PC A multi-core chip with processor cores and eight single-instruction, multiple-data (SIMD) coprocessor cores, capable of massive floating-point processing, optimized for compute-intensive workloads and broadband-rich media applications. A high-speed memory controller and a high-bandwidth bus interface are also integrated on-chip. Cell BE's breakthrough multi-core architecture and ultra-high-speed communication capabilities deliver greatly improved real-time response in many cases at 10 times the performance of the latest PC processors. Cell BE is OS neutral and sup...
