  • Publication number: 20040091106
    Abstract: An arrangement is described for scrambling data streams having arbitrary data path widths. The arrangement includes logic configured to generate a maximal length pseudorandom sequence of digital signals. A first register is configured to store the pseudorandom sequence. Logic, coupled to the first register, is configured to combine a portion of the pseudorandom sequence with a corresponding portion of an input data stream to produce a scrambled data word. A second register is configured to store the scrambled data word. Circuitry is configured to circularly shift the pseudorandom sequence a number of bits forming the portion of the pseudorandom sequence used to produce the scrambled data word.

  • Patent number: 5872940
    Abstract: A system bus controller (103) within a processor (101) includes programmable logic for different modes of chip enable signals on a per-address-space basis. This allows for a "glueless" interface (107) between the processor (101) and different types of external devices (111, 112, 113), such as memory devices. A chip select register value 604, 608, 612 is preprogrammed with respect to each external device coupled to the processor (101). This preprogrammed register value 604, 608, 612 is used by the system bus controller (103) to uniquely configure a read/write access signal to be sent to each of the external devices (111, 112, 113).

  • Patent number: 5502406
    Abstract: A low power level shift and buffer circuit (40) is used to level shift and amplify an output of an oscillator (14, 16, 18, 20, 22, 24) in a data processing application (10). A current mirror (58) and a reference current are used to provide a constant current source load for an inverter (56, 42). Separate controls for each of the two transistors forming a push/pull inverter (54, 50) eliminate a switching transient current by providing non-overlapping inputs to each of the two transistors. By eliminating the switching transient current, little power is consumed during the level shifting and amplification process. Furthermore, a significant amount of circuit area is not required and an output with fast rise and fall times is provided.

  • Patent number: 5272453
    Abstract: A method and apparatus for switching between gain curves of a switched gain voltage controlled oscillator (VCO) 52, 52' or 52". In one form, the present invention uses a switched gain voltage controlled oscillator (VCO) 52, 52' or 52" which utilizes a ring oscillator. A Gain Control signal is used to select between using a high gain curve and using a low gain curve. The low gain curve is produced by selecting a high resistance path to either power or ground. The high gain curve is produced by selecting a low resistance path to either power or ground.
