Abstract
The aim of the invention is to more flexibly use bus resources. The possibility to dynamically design the priority allocation by a arbiter (1) is provided. The arbiter allocates access rights to bus resources to several users (1, 2, X). The waiting cycles (W1, W2, W3) of the individual users (1, 2, X) are evaluated (3). Priority is newly allocated (4) according to the evaluation. The priority allocation is brought back to the arbiter (1) by means of a feedback loop (5).
