  • Adaptive hysteresis for reduced swing signalling circuits
    Patent number: 8319756
    Abstract: Apparatus (50) for processing a differential input signal. The apparatus (50) comprises a minimum peak detector (51) with a differential input (28). The peak detector (51) provides a first voltage being proportional to an average voltage peak at the peak detector's differential input (28). A compressor (53) is provided for processing the first voltage in order to provide a second voltage. The compressor (53) is followed by a voltage controllable current source providing a trim current that is adjustable by the second voltage. A hysteresis equipped circuit (67.1) whose hysteresis characteristics are adjustable by the trim current is part of the apparatus (50).

  • Method of performing access to a single-port memory device, memory access device, integrated circuit device and method of use of an integrated circuit device
    Publication number: 20050180254
    Abstract: An arbiter 15 for accessing a single-port RAM 13 without the need to use a hand-shaking protocol is proposed. This allows simultaneous read and write accesses to a single-port RAM 13. All write accesses are delayed so that the arbiter 15 can detect if there is a simultaneous read access. If there is a read access, the read access is delayed until the write access is completed.
