A system and method for determining an FFT window location for reception of an OFDM signal received over a transmission channel. The easily reworkable alpha particle barrier is applied in the space between the surface of the chip and the surface of the substrate, and reduces soft error rate. The control device detects a fuel vapor leak when the shutoff pressure is in the specified range. In the multi-thread mode, multiple threads are simultaneously executing. The applications need not change when the network processor hardware features are changed.
