The invention relates to a method in the decompression of a compressed audio signal. The method includes receiving a board device with various functional elements and on-board storage to be operatively coupled to a computing device through an interconnect. In a method for treating particulate material, the material is put into the container, and process air is introduced from the container central duct into the lower region of the process chamber and flows upwards in the process chamber in order to move the material in the process chamber. The valve is closed at a second time during the four-stroke combustion cycle. Such a network is generally applicable to semiconductor devices with various clock frequencies, and high-performance and low-power clocking requirements such as microprocessors, ASICs, and SOCs.
