Abstract: A system comprises a resource, such as an interconnection, for example, of the Network-on-Chip (NoC) type, having an overall bandwidth available for allocation to a set of initiators that compete for allocation of the overall bandwidth. The system includes a communication arbiter for allocating the overall bandwidth to the initiators according to respective values of bandwidth requested (RBW) by the initiators. A control device (50) is configured to detect the deviation between the value of bandwidth allocated to the initiators and the respective value of requested bandwidth and allocate the overall bandwidth to the initiators in a dynamic way minimizing the mean value of the deviation.

Abstract translation: 系统包括诸如片上网络（NoC）类型的诸如互连的资源，具有可用于分配给竞争总体带宽分配的一组发起者的总带宽。 该系统包括通信仲裁器，用于根据发起者所请求的带宽（RBW）的相应值将总带宽分配给发起者。 控制装置（50）被配置为检测分配给发起者的带宽值与所请求带宽的相应值之间的偏差，并以动态方式将总体带宽分配给发起者，以使偏差的平均值最小化。
