摘要： In a shared memory architecture, early coherency indication is used to notify a communications interface, prior to the data for a memory request is returned, and prior to updating a coherency directory in response to the memory request, that the return data can be used by the communications interface when it is received thereby from a source of the return data. By doing so, the communications interface can often begin forwarding the return data over its associated communication link with little or no latency once the data is retrieved from its source. In addition, the communications interface is often no longer required to wait for updating of the coherency directory to complete prior to forwarding the return data over the communication link. As such, the overall latency for handling the memory request is typically reduced.

摘要： An early return indication is used to notify a first communications interface, prior to a response being received from any of a plurality of sources coupled to a second communications interface, that the return data can be used by the first communications interface when it is received thereby from a source of the return data if the source has an exclusive copy of the return data. By doing so, the first communications interface can often prepare for forwarding the return data over its associated communication link such that the data can be forwarded with little or no latency once the data is retrieved from its source, and may be able to initiate the return of data over the communication link prior to all responses being received from the other sources. The early return indication may also serves as an early coherency indication in that the first communications interface is no longer required to wait for updating of a coherency directory to complete prior to forwarding the return data over the communication link.

摘要： A method and circuit for implementing serial link training sequences, and a design structure on which the subject circuit resides are provided. A transmitter device transmits a training sequence (TS) pattern; then the transmitter device transmits random data for a predefined time duration. The steps of transmitting the TS-pattern, then transmitting the random data for the fixed time duration are repeated. A receiver device detecting a plurality of the TS-patterns separated by the predefined time interval of random data, performs receiver initialization steps. The receiver device performs a plurality of receiver initialization steps including, for example, acquiring byte lock, and a link width determination.

摘要： Uncontested priority is provided to out-of-order data transfers over in-order data transfers on a data bus shared by a plurality of memory requesters. By always granting priority to out-of-order transfers such as deferred read data transfers over in-order transfers such as write and/or cache-to-cache data transfers, it is assured that no newer command or transaction ever negatively affects the latency of an older command or transaction.

摘要： A method, and apparatus are provided for implementing processor bus speculative data completion in a computer system. A memory controller in the computer system sends uncorrected data from a memory to a processor bus. The memory controller also applies the uncorrected data to error correcting code (ECC) checking and correcting circuit. When a single bit error (SBE) is detected, corrected data is sent to the processor bus a predefined number of cycles after the uncorrected data.
