A mechanism is provided for controlling the heat output of a controller by monitoring the temperature of the controller using an embedded heat sensor. The IO processor monitors the temperature and controls the rate of the IO flow to control the temperature. The IO processor accomplishes this by checking the current temperature every time it gets a timer interrupt. If the temperature becomes too high, the IO processor may slow down the processor speeds in the controller. The IO processor may also slow down the throughput by inserting a delay between each IO request processed. Furthermore, the IO processor may slow down the rate at which data is passed onto the bus. Still further, the IO processor may insert a delay between batches of IO requests. By slowing down the IO flow, the IO processor decreases the overall power consumption and, thus, controls the heat output.

When a power amplifier control loop operates near or in saturation, the quality of the output signal can be degraded and an over current condition can occur. To prevent this, the output signal of the power amplifier is detected, converted to digital, and then converted into the frequency spectrum by means of a Fast Fourier Transform. The spectral characteristics of the output signal are analyzed to determine if the power amplifier control loop is approaching or operating in saturation mode. This determination is made by looking at the power of the output signal at various frequencies. If the output at these frequencies exceeds a threshold value, the power amplifier control loop is approaching saturation. In this situation, the output of the power amplifier can be adjusted to prevent loop saturation. This can be accomplished by reducing the supply voltage to the power amplifier or adjusting the bias voltage.
