  • Publication number: 20100111244
    Abstract: Over the years, ring counter and prescalers have been used in a variety of microelectronic applications, including Phased Locked Loops or PLLs. All of these applications have experienced both decreases in size and increases in speed. As a result, current-mode logic or CML has come into use in some high speed applications, calling for alternative designs for components such as prescalers. Here, a divide-by-three prescaler is described that uses internal states from mater-slave flip-flop pairs and that is well-suited for microelectronics that employ CML.

  • Patent number: 7712098
    Abstract: A digital system and method of operation is provided in which several processors (440, 450) are connected to a shared memory resource (460). Translation lookaside buffers (TLB) (400, 402) are connected to receive a request address (404a-n) from each respective processor. Each TLB has a set of entries that correspond to pages of address space. Each entry provides a set of task memory attributes (TMA) (412a-n) for the associated page of address space. Task memory attributes are defined by a task control block associated with a currently executing task. For each memory transfer request, the TLB accesses an entry corresponding to the request address and provides a translated physical memory address and a task memory attribute value associated with that requested address space page. Functional circuitry (470) performs pre/post-processing on data that is being transferred between a processor and the memory in accordance with the task memory attribute value provided by the TLB with each memory transfer request.

  • Patent number: 7709329
    Abstract: Formation of an electrostatic discharge (ESD) protection device having a desired breakdown voltage (BV) is disclosed. The breakdown voltage (BV) of the device can be set, at least in part, by varying the degree to which a surface junction between two doped areas is covered. This junction can be covered in one embodiment by a dielectric material and/or a semiconductor material. Moreover, a variable breakdown voltage can be established by concurrently forming, in a single process flow, multiple diodes that have different breakdown voltages, where the diodes are also formed concurrently with circuitry that is to be protected. To generate the variable or different breakdown voltages, respective edges of isolation regions can be extended to cover more of the surface junctions of different diodes. In this manner, a first diode can have a first breakdown voltage (BV1), a second diode can have a second breakdown voltage (BV2), a third diode can have a third breakdown voltage (BV3), etc.

  • Patent number: 7710296
    Abstract: A method of context adaptive binary arithmetic coding and decoding groups a plurality N binary symbols in corresponding syntax elements and divides a range into 2N subranges based upon corresponding contexts. The invention encodes data by selecting an offset determined by the probability states of the context of the N binary symbols. Decoding is similar with the place of the coded offset within the 2N subranges determining the syntax decoding. When the total number of binary symbols to be coded does not equal an integral multiple of N, the invention codes dummy binary symbols at the end of a grouping of a plurality N binary symbols. Probability state updates occur only following every N binary symbols.

  • Patent number: 7710350
    Abstract: According to one embodiment, a method for providing position feedback for a device includes providing a photointerrupter having a light-emitting diode, a phototransistor, and an aperture between the light-emitting diode and the phototransistor. For a given size aperture, a current through the phototransistor is a function of a current through the light-emitting diode. The method also includes controlling the current through the light-emitting diode current such that a change in the effective aperture size results in a desired approximately proportional change in current through the phototransistor. While controlling the current through the light-emitting diode, a portion of the aperture is blocked by an arm that has a position indicative of the position of the device. The method also includes providing a signal indicative of the change in current through the photodiode as an indication of the change in position of the device.

  • Publication number: 20100103380
    Abstract: The present invention relates to an optical projection illumination module that projects highly uniform radiative energy (e.g., visible light, ultraviolet radiation, infrared radiation, etc.) onto a target area. More particularly, the illumination module comprises a radiative energy source (e.g., a LED) configured to provide divergent radiative energy (e.g., a non-uniform illumination) directly to a reflective tunnel (e.g., a total internal reflection tunnel), separated from the radiative energy source by a small gap and optically in contact (e.g., physically coupled) to a front optical element (e.g., collimator lens). The reflective tunnel mixes the divergent radiative energy, and outputs a substantially uniform radiative energy to a front optical element. One or more downstream optical elements image the output of the reflective tunnel directly to the target area (i.e., the object imaged on to the target area is located on an image plane embedded between the reflective tunnel and the front optical element).
