A method for processing data is provided that includes receiving a clock signal at a source driver and communicating the clock signal to a plurality of destination receivers. The clock signal may be received at the destination receivers during a substantially equivalent time interval, the plurality of destination receivers being five.

Method and apparatus for providing a clock signal to a plurality of destination receivers in an integrated circuit environment

Generating a message digest includes selecting a first hashing procedure or a second hashing procedure for a message having words. If the first hashing procedure is selected, a first function is applied to a first subset of words at a function module to yield a first function output, and a second subset of words and the first function output are combined at an adder to yield a first sum. Next words are generated in accordance with the first sum. If the second hashing procedure is selected, a second function is applied to a third subset of words at the function module to yield a second function output, and a fourth subset of words and the second function output are combined at the adder to yield a second sum. Next words are generated in accordance with the second sum.

Generating message digests according to multiple hashing procedures

A method for processing data is provided that includes receiving a first request in a first clock cycle from a processor for access to a first data segment corresponding to a first address included in the first request. A second request for access to a second data segment corresponding to a second address included in the second request is received during a second clock cycle. The second data segment is disabled from being communicated to the processor and the first data segment is communicated to the processor in response to the second request.
