    摘要: Design structures embodied in machine readable medium are provided. Embodiments of the design structures include a multimodal memory controller comprising: a transceiver circuit having at least one internal signal line, a first external signal line, a second external signal line, and a mode control signal line, the mode control signal line having asserted upon it a mode control signal, and the transceiver circuit configured to operate the external signal lines for single-ended signaling at a first voltage when the mode control signal is a first value and to operate the external signal lines for differential signaling at a second voltage when the mode control signal is a second value.

    摘要: Switching characteristics of system components are represented and summed so that their effects on the overall system can be observed during the design process. Full simultaneous switching analysis is provided at the earliest levels of design containing minimal level of design data by a method of computing net based simultaneous switching noise levels which supports packages ranging from the smallest chip level to the largest board level. The simultaneous switching activity is computed based on interaction between each driver and each other driver between each component and each other component, with consideration to the spatial inter-relationship net, within a higher level component, to determine each component's drivers effect on itself as well as the coupling effect between drivers on different components. The analysis involves computing simultaneous switching noise by associating a characteristic triangle with each driver application configuration. The characteristic triangle. The height of the triangle, as well as the pitch of the sides of the triangle will be determined by the characteristics of the net. In the early stages of design, a default characteristic triangle is defined for each technology type. A general triangle is also defined for cases where early analysis needs to be performed prior to choosing a technology.

    摘要: A subpicosecond solid state optical correlator based on interference induced carrier modulation includes a photosensor circuit having a photoconductive element and a pair of opposed electrodes. A voltage difference is created across the electrodes to define an electrical field direction, and the element operates to generate charge carriers in response to optical energy incident on the photoconductive element. First and second optical signals are directed onto the photoconductive element to form an interference pattern thereon when the signals overlap in time and space. This interference pattern produces spatial modulation of the distribution of the carriers into lines or planes, at least some of which are not parallel to the electrical field direction. The resulting photocurrent is monitored to detect a parameter associated with the presence or absence of the interference pattern. The interference pattern defines a characteristic nodal spacing between adjacent ones of the lines, and the carriers include higher mobility carriers and lower mobility carriers. The ambipolar diffusion length is no greater than the characteristic nodal spacing, and an integrated value of the photocurrent is therefore less when the optical signals overlap in optical frequency and time and form the interference pattern than when the optical signals do not overlap in optical frequency and time.
