An integrated circuit comprising a plurality of modules for processing applications, a global memory, which can be shared by said plurality of modules, an interconnect means for interconnecting said modules and said global memory based on a plurality of communication services is provided. Each of the headphones includes a housing having a first wall, a second wall and a peripheral wall extending between the first and second walls. Simultaneously, a timer of the controller 61 is operated to begin counting an incremental time. The pedal position is converted to a respective instantaneous wheel output demand in response to an initial value from a mapping relationship that is modified in response to a difference between the initial value and the variable pull-up threshold.
