摘要:
A data processing device includes an interconnect controller operable to manage the communication of information between modules of the data processing device via an interconnect. In response to a transaction request the interconnect controller selects a tag value from a set of available tag values, assigns the tag to the transaction and reserves the tag value so that it is unavailable for assignment to other transactions. If an expected response to the transaction request is not received within a designated amount of time, the transaction enters a timed-out state and the interconnect controller locks the tag value, so that it remains unavailable for assignment to other transactions until an unlock event, such as a request from software.

During polishing of a first substrate at a first polishing station, a sequence of measurements by a first in-situ monitoring system is monitored to determining a first time at which the first sequence exhibits a first predefined feature indicating a predetermined thickness of an overlying layer, and during polishing of the first substrate at a second polishing station, a sequence of measurements by a second in-situ monitoring system is monitored to determine a second time indicating clearance of the overlying layer and exposure of the underlying layer. The first time is used to calculate a first adjusted polishing pressure for a second substrate at the first polishing station, and the second time is used to calculate a second adjusted polishing pressure for the second substrate at the second polishing station.

A source processor can divide each packet of a data stream into multiple segments prior to communication of the packet, allowing a packet to be transmitted in smaller chunks. The source processor can process the segments for two or more packets for a given data stream concurrently, and provide appropriate context information in each segments header to facilitate in order transmission and reception of the packets represented by the individual segments. Similarly, a destination processor can receive the packet segments packets for an ordered data stream from a source processor, and can assign different contexts, based upon the context information in each segments header. When a last segment is received for a particular packet, the context for the particular packet is closed, and a descriptor for the packet is sent to a queue. The order in which the last segments of the packets are transmitted maintains order amongst the packets.

A DMA controller allocates space at a buffer to different DMA engines based on the length of time data segments have been stored at a buffer. This allocation ensures that DMA engines associated with a destination that is experiencing higher congestion will be assigned less buffer space than a destination that is experiencing lower congestion. Further, the DMA controller is able to adapt to changing congestion conditions at the transfer destinations.

A data processing system employs an improved arbitration process in selecting pending memory access requests received from the one or more processor cores for servicing by the memory. The arbitration process uses memory timing and state information pertaining both to memory access requests already submitted to the memory for servicing and to the pending memory access requests which have not yet been selected for servicing by the memory. The memory timing and state information may be predicted memory timing and state information; that is, the component of the data processing system that implements the improved scheduling algorithm may not be able to determine the exact point in time at which a memory controller initiates a memory access for a corresponding memory access request and thus the component maintains information that estimates or otherwise predicts the particular state of the memory at any given time.

A slip rate detection method and a detection system for detecting the slip rate of an electric vehicle using the method. The slip rate of an electric vehicle is measured by measuring the motor voltage, motor current, and motor rotational speed of the drive motor. The detection system includes a motor rotational speed detection unit, a motor voltage detection unit, and a motor current detection unit, all connected to the drive motor. The motor rotational speed detection unit, the motor voltage detection unit, and the motor current detection unit are connected to a slip rate calculation unit by means of a motor rotational speed signal processing unit, a voltage signal processing unit, and a current signal processing unit, respectively. The slip rate calculation unit is configured with a slip rate calculation formula. The formula is determined according to the drive motor type.

A method of controlling polishing includes storing a desired ratio representing a ratio for a clearance time of a first zone of a substrate to a clearance time of a second zone of the substrate. During polishing of a first substrate, an overlying layer is monitored, a sequence of measurements is generated, and the measurements are sorted a first group associated with the first zone of the substrate and a second group associated with the second zone on the substrate. A first time and a second time at which the overlying layer is cleared is determined based on the measurements from the first group and the second group, respectively. At least one adjusted polishing pressure is calculated for the first zone based on a first pressure applied in the first zone during polishing the first substrate, the first time, the second time, and the desired ratio.

A method of chemical mechanical polishing a substrate includes polishing a plurality of discrete separated metal features of a layer on the substrate at a polishing station, using an eddy current monitoring system to monitor thickness of the metal features in the layer, and controlling pressures applied by a carrier head to the substrate during polishing of the layer at the polishing station based on thickness measurements of the metal features from the eddy current monitoring system to reduce differences between an expected thickness profile of the metal feature and a target profile.
摘要:
A method includes storing a first transaction entry to a first software configurable storage location, storing a second transaction entry to a second software configurable storage location, determining that a first transaction indicated by the first transaction entry has occurred, determining that a second transaction indicated by the second transaction entry has occurred subsequent to the first transaction, and, in response to determining that the first transaction occurred and the second transaction occurred, storing at least one transaction attribute captured during at least one clock cycle subsequent to the second transaction. The first and second software configurable storage locations may be located in a trace buffer, where the at least one transaction attribute is stored to the trace buffer and overwrites the first and second transaction attributes. Each transaction entry may include a dead cycle field, a consecutive transaction requirement field, and a last entry field.
摘要:
A method and system for providing dynamic branding for a computer program or suite having windows, screens, display elements in a graphical interface. The system comprises a branding service module and a branding files database. The database includes a schema for storing and accessing the branding files. The branding files comprise graphical elements and/or textual elements, which can be modified and updated.
