摘要： Systems and methods to respond to error detection are provided. A particular method may include issuing a first command to a first redrive device and a second command to a second redrive device. The method may also include reissuing the second command to the second redrive device in response to detecting a transmission error between a memory controller and the second redrive device. The method may further include storing at a first buffer first data that is received from the first redrive device in response to the first command. The method may include storing at a second buffer second data that is received from the second redrive device in response to the reissued second command. The method also may include merging the second data with the first data.

摘要： In a method of handling errors in a digital system that includes a root complex in data communication with at least one endpoint, the endpoint including at least one advanced error reporting register, an error is detected by the endpoint. Error data indicative of the error is stored in an advanced error reporting register. An indication of which transaction caused the error is stored in a secondary location. An error message packet that includes the error data and the indication of which transaction caused the error is generated. The error message packet is transmitted to the root complex. The root complex is caused to take a preselected action in response to the error message packet.

摘要： In a method for enabling a root device to access a plurality of memory locations in an address space in an endpoint device, a first access is sent to the endpoint device by transmitting a first header and a first address. The header includes a continue bit that is set at a first state that indicates that the first access is accessing a selected first memory location that the address is being sent. A first memory location is accessed when the continue bit is in the first state. A second access, which accesses accessing a second memory location that is contiguous to an immediately previously accessed memory location, is sent to the endpoint device by transmitting a header that includes a continue bit set to a second state and not sending an address. The second memory location corresponds to the first address plus a predetermined address offset.

摘要： Systems and methods to manage memory refreshes at a memory controller are disclosed. A method includes determining, at a memory controller device, that a number of transmission errors between a memory controller port and a memory redrive device exceeds an error threshold. The method may include initiating a first link retraining process between the memory controller port and the memory redrive device. The method may further include placing one or more dynamic random access memory modules associated with the memory redrive device in a self-refresh mode. The method may also include removing the one or more dynamic random access memory modules from the self-refresh mode after the link retraining process has completed. The method may further include enabling overlapping refreshes of the one or more dynamic random access memory modules.

摘要： A compressed replay buffer in a first electronic unit of an electronic system holds commands in a table. As commands are transmitted from the first electronic unit to a second electronic unit, the command, along with associated data, command type, and the like are stored in a row in the table. No rows in the table contain “dead cycles” to indicate that no command was sent on a particular cycle on a bus over which the commands were transmitted. The second electronic unit may request that the first electronic unit replay some number of commands. In response, the first electronic unit uses commands in the compressed replay buffer, along with required timings stored on the first electronic unit, to replay the number of commands requested.

摘要： A technique for handling commands includes assigning respective first tags to ordered commands included in an ordered command stream. Respective second tags are then assigned to subsequent commands that follow an initial command (included in the ordered commands). Each of the respective second tags correspond to one the respective first tags that is associated with an immediate previous one of the ordered commands. The initial command is sent to an execution engine in a first cycle. At least one of the subsequent commands is sent to the execution engine prior to completion of execution of the initial command.
