    摘要: A method and apparatus for meeting compliance for debugging and testing a multi-speed, point-to-point link. In one embodiment, the method includes the selection of a compliance speed for a point-to-point link from at least two link frequencies supported by the point-to-point link. Once the compliance speed is selected for the point-to-point link, the point-to-point link is caused to enter a compliance testing mode. During compliance testing mode, a controller of the point-to-point link sets a compliance speed of the point-to-point link to the selected compliance speed. Once a compliance speed is set, a transmitter of the point-to-point link transmits a compliance pattern at the selected compliance speed. In one embodiment, the transmission of the compliance pattern at the selected compliance speed is used to generate a worst case eye diagram to determine compliance of the point-to-point link to a link specification. Other embodiments are described and claimed.

    摘要: Various embodiments of the invention provide a frequency shifter to vary the frequency of data transmitted over time, such as to increase and decrease the frequency of test data transmitted over time to verify a digital communication device's ability to receive data having various frequencies within a specific parameter range. The frequency shifter includes a frequency modifier to shift or vary an input clock frequency to a variety of output clock frequencies, such as according to a test protocol. The frequency shifter also includes an elastic data buffer to receive the test data at the input clock frequency and to output the test data at the plurality of output clock frequencies provided by the frequency modifier.

    摘要: Various embodiments of the invention relate to an apparatus and method for efficiently implementing out-of-order servicing of read requests originating from an input/output (I/O) interface with minimal additional storage. For example, a number of read entries may be generated from data read requests stored in a first-in-first-out in a first order. The read entries are stored in a storage device and each read entry identifies internal data reads to read data to service the data read request to which the read entry corresponds. A controller coupled to the storage structure may then submit the internal data reads a central arbiter to read data in a second order that is different than the first order. Moreover, the controller also allows the second order to include internal data reads from one read entry, before a completing servicing of another partially serviced read entry, thus providing “simultaneous” servicing of several read entries.
