    • A controller and method are provided for monitoring and controlling a temperature of an integrated circuit to inhibit damage from a thermal problem. The controller and method allow for individual temperature thresholds for each of one or more temperature sensors. Digital filtering of values received from temperature sensors is also provided. A variety of actions can be selected for execution upon a determination of an over-temperature condition of the integrated circuit, including assert an over-temperature pin, assert an over-temperature bit in an error register of said controller, assert an over-temperature bit in an error register of said microprocessor, issue an over-temperature interrupt to a service bus of said integrated circuit, cause a trap, slow an operating frequency of said integrated circuit, stop said integrated circuit, and do nothing.
    • 提供了一种控制器和方法,用于监测和控制集成电路的温度以抑制热问题的损坏。 控制器和方法允许一个或多个温度传感器中的每个温度阈值。 还提供了从温度传感器接收的值的数字滤波。 在确定集成电路的过热状态(包括断言过温引脚)时,可以选择执行各种动作,断言所述控制器的错误寄存器中的过温度位,断言过温度 位在所述微处理器的错误寄存器中,向所述集成电路的服务总线发出过温中断,引起陷阱,使所述集成电路的工作频率变慢,停止所述集成电路,并且不做任何事情。
