    摘要: A method for compensating for variations in timing of data sent to a processor on data bit lines relative to a strobe clock sent to the processor on a strobe clock line that can be used in a dual data rate (DDR) memory identifies discrete minimum and maximum time offset values for test data in selected data bit patterns for the data bit lines. The discrete minimum time offset value is the minimum timing adjustment required to allow the processor to receive the data in a steady-state condition during a data valid window of the strobe clock and the discrete maximum time offset value is a maximum timing adjustment required to allow the processor to receive the data in a steady-state condition during a data valid window of the strobe clock. The discrete minimum and maximum time offset values identify a valid range when the data bit lines supply data in a steady-state condition for latching into the processor by the strobe clock.

    摘要: A system on a chip (SOC) includes a physical interface having first and second sets of interface pads. Interface pads from the first set are interleaved with interface pads from the second set. Additionally, the SOC is arranged for operation with a superset die having first and second personalities and has a physical interface with interface pads. The SOC uses a first number of interface pads in the first personality and a second number of interface pads in the second personality, where the first number is greater than the second number. A switch switches signals between the superset die and the physical interface and, in the second personality, switches signals to the physical interface so that interface pads in the second number of interface pads are interleaved with interface pads not in use in the second personality.
