    • A method for adapting a bus to data traffic in a system comprising several functional units (311, 312, , 31n) and a bus structure. The functional units are divided into at least two sets so that units, which mainly transfer data with each other belong to a same set and are interfaced with the same separate sub-bus (321; 322). The sub-buses can be united by switches (SW) into a broader bus, which is only used when data must be transferred between different sets. Supply voltage of each sub-bus is adjustable and is set the lower the less traffic there is on the bus. The parallel transfer operation makes it possible to increase the transfer capacity of the bus structure without increasing it's clock frequency. Furthermore energy consumption can be reduced by dropping the supply voltage of the bus circuits so that the bus retains the transfer capacity needed.
    • 一种用于将总线适配到包括多个功能单元(311,312,,31n)和总线结构的系统中的数据业务的方法。 功能单元被划分为至少两组,使得主要将数据彼此传输的单元属于同一组并且与相同的单独子总线(321; 322)接口。 子总线可以通过开关(SW)组合成更宽的总线,仅在不同组之间传输数据时才使用。 每个子总线的电源电压是可调的,并且设置在总线上的流量越少。 并行传送操作使得可以增加总线结构的传输容量而不增加其时钟频率。 此外,可以通过降低总线电路的电源电压来降低能量消耗,使得总线保持所需的传输容量。
