    摘要: A method and apparatus for performing byte rate adaptation. Specifically, embodiments of the present invention describe a method for deleting bytes when performing byte rate adaptation. The method begins by receiving data at a first rate. The data comprises valid data and deletable data. The data also comprises a plurality of cycles, wherein each cycle comprises a word length of W bytes. The method continues by compressing the plurality of cycles into a compressed cycle by deleting redundant deletable bytes. The compressed cycle comprises at least one valid data byte. Thereafter, the method substitutes remaining deletable bytes in the first compressed cycle with a uniform character, and sends the compressed cycle to a FIFO buffer for further transmission.

    摘要: A method for multi-bit de-skewing of parallel bus signals is disclosed. The method includes receiving data comprising a multi-bit word and a training pattern. After a first control word of the training pattern is detected, the number of bits needed to de-skew each data bit of a multi-bit data word in each bit-line of a parallel bus is calculated. The number of bits needed to de-skew each data bit of a multi-bit data word in each bit-line of the parallel bus is transmitted to a bit delay line. The system then outputs a de-skewed data word.

    摘要: A method and processor configured to handle an exception may employ a “retry” signal, which may be associated with a memory access attempt by the processor. The retry signal determines if an exception is to be serviced during a period in which the memory access is delayed. In one embodiment for which the exception is an interrupt, the retry signal is asserted when memory access is delayed and the processor may proceed to service an interrupt request during this period of delayed memory access, regardless of the degree of completion of an instruction by the processor. During a period of delayed memory access, the processor may suspend instruction execution until the memory access becomes available. Upon completion of servicing the interrupt, the processor may resume instruction execution beginning with the last instruction attempted before the suspension of the instruction execution due to the delayed memory access. In one embodiment, the processor may include interrupt handling logic to enable initiation of interrupt service in response to an interrupt request and may further include address selection logic to select an instruction address associated with a delayed memory access.
