摘要： Embodiments of the present invention relate to instruction fetching in data processing systems. One aspect involves a data processor (202) to execute instructions and to fetch instructions from a memory (208) according to a fetch size. This data processor (202) comprises a first input (212) to receive instructions, control logic (402) to decode the instructions, and an instruction pipeline (400) coupled to the first input (212) and the control logic (400). The instruction pipeline (400) is responsive to a first signal (214) to set the fetch size to one of a first size and a second size. The data processor (202) therefore allows an instruction fetch policy to be altered based on the characteristics of an accessed device in order to achieve improved performance.

摘要： A fiber optic device and a method of assembling the fiber optic device to provide at least four degrees of adjustment for an optical beam transported between an optical fiber and bulk optics in an optical device package. At an opening in the wall of the optical processor package, a washer-like structure allows initially adjustable contact at a flat surface thereof and at a spherically curved surface thereof. One of the surfaces bears against the wall about the opening and the other surface bears against a contact feature of a connecting assembly, typically a pre-assembled collimator assembly, that holds a termination portion of the optical fiber. Translational adjustment is made at the flat surface and tilting adjustment is made at the curved surface before final attachment at both surfaces. The fiber optic device is thus aligned with the optical device package and, through that package, can be aligned with another connecting assembly that is initially fixed in place at another opening of the optical device package. Circumferential tapers are provided at appropriate ones of the surfaces, the wall, and the contact feature to facilitate adhesive flow for final attachment.

摘要： Ring-detect interface circuit is disclosed for digital DAA circuitry to provide a plurality of selectable signals, including a ring monitor signal, on a ring-detect output pin. The interface circuitry allows the digital DAA circuitry to interface with advanced controllers, such as advanced DSPs, while still being compatible with older controllers that expect only a ring monitor signal on the ring-detect pin. The interface circuitry may include a multiplexer that receives multiple status bits or signals, including the ring monitor signal, and that has its output controlled by a multiple-bit control register. In addition, the ring monitor signal may be communicated as a digital signal across an isolation barrier from phone line side circuitry to powered side circuitry and ultimately made available on the ring-detect output pin. Corresponding methods for improving compatibility of digital DAA circuitry through the ring-detect interface circuit are also disclosed.

摘要： A communication system having a framing pattern to frame data to be transmitted to a phone line is provided. The data may be framed on one side of an isolation barrier and a clock signal may be extracted from the framed data stream on the other side of the barrier. The data to be framed is provided from an output of a delta-sigma modulator and the framing pattern utilized is a pattern that is unlikely to match the data stream output of the modulator. Thus, an erroneous detection of the framing pattern is unlikely to occur. The framing pattern is chosen to correspond to the expected modulator output for a full scale input signal that is at a frequency higher than the maximum actual frequency of the input data provided to the modulator.

摘要： A specific implementation is disclosed where a backward branch address instruction is fetched at a branch address. The backward branch instruction has an offset value to define the size of a program loop. A counter is set to a value that is proportional to the size of the loop. In one example the counter is set to the offset value. As each instruction of the loop is executed the counter is modified to indicate a remaining number of instructions in the loop. When no instructions remain in the current pass of the loop, the counter is reset to the offset value and the loop is repeated until a termination condition encountered. As part of the implementation the instruction after the branch instruction is read and stored prior to the loop being executed.

摘要： A monolithically integrated VCSEL and photodetector, and a method of manufacturing the same, are disclosed for applications where the VCSEL and photodetector require separate operation such as duplex serial data communications applications. A first embodiment integrates a VCSEL with an MSM photodetector on a semi-insulating substrate. A second embodiment builds layers of a p-i-n photodiode on top of layers forming a VCSEL using a standard VCSEL process. The p-i-n layers are etched away in areas where VCSELs are to be formed and left where photodetectors are to be formed. The VCSELs underlying the photodetectors are inoperable, and serve to recirculate photons which are not initially absorbed back into the photodetector. The transmit and receive pairs are packaged into a single package for interface to multifiber ferrules. The distance between the devices is precisely defined photolithographically, thereby making alignment easier. In a further alternate embodiment, a FET is coupled to the p-i-n photodiode to form an integrated detector preamplifier along with the VCSEL transmitter all on the same optical reference plane.

摘要： Monitor circuitry is disclosed that produces a loop current monitor signal indicative of the DC loop current passing through DC holding circuitry, which may be part of phone line side circuitry that may be connected to phone lines. This loop current monitor signal may be digitized and then communicated across an isolation barrier to powered side circuitry as digital information representative of the DC loop current levels in the phone lines. Example embodiments for the monitor circuitry are also disclosed, such as a MOS transistor, for which the monitor signal is the drain current of the MOS transistor, and an external resistor, for which the monitor signal is a voltage associated with the external resistor.

A first time constant may be utilized during a first operation phase immediately after off-hook conditions to allow for fast settling times. Then, a second operation phase is entered in which a second time constant may be utilized. During the second operation phase the DC holding circuit operates slower to create improved low frequency performance.

摘要： An analog successive approximation (SAR) analog-to-digital converter (ADC) is disclosed that is a compromise between a SAR ADC implementation and a fully parallel thermometer-to-binary ADC. The analog SAR ADC utilizes N comparators for N bits of output and does not require a clock system, control logic, decode logic, or thermometer-to-binary decode circuitry. Conversion speed is determined by the comparator rate, and the comparator outputs may be used directly as the ADC outputs. The analog SAR ADC disclosed is a low complexity, low-precision analog-to-digital converter (ADC) that may be used to digitize phone line status information so that it may be communicated across a isolation barrier as digital information.
