摘要： A method for allocating bus access rights is used in a multimaster bus system wherein addresses are explicitly allocated to master devices and each master device is assigned a priority value from an organized priority list of priority values. Requests from at least one master device to use the bus system to access a slave device are received, and the priority values of all requesting master devices are compared. If a sole requesting master device has the highest priority value access to the respective slave device is granted to that master device. If a plurality of requesting master devices have the same highest priority value access is successively granted to the requesting master devices having the same highest priority value on the basis of the address allocation of the master devices.

摘要： The invention relates to a memory arrangement for processing data and to a method for operating this memory arrangement. The inventive method involves a control signal being transferred together with the data on, with a change in the control signal activating the DLL circuit and synchronizing it to a clock. In this case, the DLL circuit stipulates a sampling time for the data. In line with the invention, after a predetermined length of time within which no data have been read from the memory, the memory is accessed artificially in order to generate a change in the control signal for the DLL circuit.

摘要： An arrangement comprises a memory device for storing data, and a program-controlled unit with a memory interface for reading data out of the memory device. The memory device is supplied with a first clock signal and transmits the data at the rate of a second clock signal, and the second clock signal to the memory interface when the memory interface performs a read access. The first clock signal is also supplied to the memory interface which generates from this signal a third clock signal which has the same frequency as the first and second clock signal but a predetermined phase shift with respect to the second clock signal. The memory interface accepts the data with the rising and/or falling edges of the third clock signal or the inverted third clock signal, and the third clock signal is also used as clock signal by other components of the memory interface.

摘要： An apparatus for profiling a computer system, where the apparatus contains a resolution register, a counter, and a monitor. The resolution register stores a variable, which sets the timing for when the apparatus will create an output that can be used to gauge the system's performance. The counter counts the operations of the system, while the monitor monitors occurrences, activities that occur during each operation. Once the number of operations lapse equal to the variable, a reading is output.

摘要： A configuration and method for operating the configuration includes first and second devices connected to one another through a cross bar and accessing one another through the cross bar for reading and/or writing data. When a read access to the second device occurs, the first device reads the data emitted from the second device when it receives a ready signal produced by the second device and supplied to the first device through the cross bar, and, when a write access occurs from the first device to the second device, the first device emits the data to be written to the second device when it receives a ready signal produced by the second device and supplied to the first device through the cross bar and the second device reads the data emitted from the first device when it receives a data valid signal produced by the first device and supplied to the second device through the cross bar.

摘要： Method of determining information about the processes which run in a program-controlled unit during the execution of a program by the program-controlled unit A description is given of a method of determining information about the processes which run in a program-controlled unit during the execution of a program by the program-controlled unit. The method described is distinguished by the fact that identical items of individual information about processes of the same type are combined to form a single item of overall information. As a result, the desired information about the processes of interest can be procured with considerably less expenditure than was the case hitherto.
