摘要： A method and apparatus for generating Gray code for any even count value to enable efficient pointer exchange mechanisms in asynchronous FIFO's. Allowing Gray code for any range of even count values provides the benefit of decreasing metastability when exchanging pointers for FIFO buffers in asynchronous environments. Utilizing the Gray code adjacency principle, which provides that only one bit changes for any successive numbers, in a larger class of numbers than previously utilized, decreases metastability.

摘要： A method and apparatus to perform aging are described. A method to perform timing comprises receiving an address and retrieving an age zone value associated with the received address. A time is then determined using the retrieved age zone value. The determined time may then be associated with the received address.

摘要： According to some embodiments, a parity check is provided for ternary content addressable memory. For example, it may be arranged for a read request to be transmitted to a ternary content addressable memory unit. Data content may then be received from the memory unit in response to the read request, a parity check may be performed on the data content. According to some embodiments, parity information may be masked when the memory unit is queried.
