    摘要： An I/O controller and method are provided. The I/O controller (3) to which an I/O device (4) can be connected, and which instructs the I/O device to execute a process, includes a descriptor transfer device (1) that transfers a descriptor indicating contents of a process to be executed, and execution instruction unit (31) that instructs the I/O device to execute the process, based on the descriptor transferred from the descriptor transfer device (1). The descriptor transfer device (1) includes a memory (12) for storing the descriptor; descriptor reading unit (11) that reads, according to an indication regarding a descriptor read source from a processor, an indicated descriptor from a main memory or said memory which stores the descriptor, and the descriptor transfer device (1) transfers the read descriptor to the execution instruction unit (31).

    摘要： The invention relates to the field of integrated circuits having a communication interface, such as micro controllers and / or systems on chip which need to communicate with a variety of peripheral devices.
    An object of the present invention is to provide an improved integrated circuit which alleviates the disadvantages of the prior art that a specific register interface and a specific driver software has to be provided for each communication interface.
    According to the invention this is achieved by an integrated circuit comprising a primary processing unit and at least a first and a second communication interface (CI1,CI2,CIN) for the primary processing unit for communicating in accordance with at least a first and a second communication protocol, characterized in that a set of registers of the communication interface (CI1,CI2,CIN) are arranged such that a specific register functionality is accessible independently of a selection of the first or the second communication interface (CI1,CI2,CIN).

    摘要： The invention relates to a system that consists of at least two components and that is usually dimensioned in such a manner that the capacity of the components is increasing towards the exterior of the system. If this dimensioning is not fulfilled for any of the components, a bottleneck occurs that may cause a reception overload on the very component that represents the bottleneck. The invention solves this problem by providing a specific kind of flow control.
