摘要： A method that dynamically adjusts link control parameters of a communications network. The communications network includes a transmitter coupled through a first data link to a receiver. The transmitter and receiver each have at least one associated link control parameter that affects the operation of that component. According to one method, data signals are transmitted over the first data link and the transmitted data signals are captured. The values of the captured data signals are compared to expected values for those signals, and the values of the link control parameters are adjusted to successfully capture the transmitted digital signals.

摘要： Memory system controllers can include hardware masters, first buffers, and a switch coupled to the hardware masters and to the first buffers. The switch can include second buffers and a buffer allocation management (BAM) circuit. The BAM circuit can include a buffer tag pool. The buffer tag pool can include tags, each identifying a respective first buffer or a respective second buffer. The BAM circuit can be configured to allocate a tag to a hardware master in response to an allocation request from the hardware masters. The BAM circuit can be configured to prioritize allocation of a tag identifying a second buffer over a tag identifying a first buffer.

摘要： A processor-based electronic system includes several memory modules arranged in first and second ranks. The memory modules in the first rank are directly accessed by any of several processors, and the memory modules in the second rank are accessed by the processors through the memory modules in the first rank. The data bandwidth between the processors and the memory modules in the second rank is varied by varying the number of memory modules in the first rank that are used to access the memory module in the second set. Each of the memory modules includes several memory devices coupled to a memory hub. The memory hub includes a memory controller coupled to each memory device, a link interface coupled to a respective processor or memory module, and a cross bar switch coupling any of the memory controllers to any of the link interfaces.
