摘要: A data processing system having a compression and decompression apparatus based on the Lempel-Ziv algorithm. The compression apparatus includes an array section having a circular history CAM unit for receiving and storing one or more data elements and a coding unit for determining whether received data elements previously have been stored in the history CAM unit and are a candidate for compression. If a received data element matches at least one of the stored data elements, a PS logic section determines whether there is the presence of a string. An encoding section identifies the address of the matching stored data element in a string and the length of the string. The compression apparatus generates a compression token comprising an identification of whether a data element is compressed, the length of the coded data within a plurality of predetermined data length categories and an address. The compression apparatus uses a particular hardware implementation of the PS logic section.

摘要: A voltage boosting circuit for an "H-driver," providing for each "pull-up" switch in the H-driver a switching shunt that charges a capacitor from a supply voltage when the "pull-up" switch is open and couples the capacitor directly to the write head when the "pull-up" switch is closed. The side of the capacitor which is not directly coupled to the write head is coupled to the data signal (or its inverse, in the case of the capacitor for the otherwise identical circuit serving the parallel half of the "H-driver") through a buffer which sets the voltage at the signal level (or its inverse), thereby dumping the charge to the write head and elevating the voltage of the write head significantly above the supply voltage. The identical circuit serving the parallel half of the "H-driver" similarly boosts the negative going transition voltage.

摘要: According to the preferred embodiment, a self-biased phase-locked loop is provided that overcomes the limitations of the prior art bias methods and apparatus. In general, a self-biased current controlled semiconductor device, typically a current controlled oscillator, is self biased by the use of a first feedback path, typically provided by a phase-locked loop, where the feedback path provides a control current for controlling the current controlled device. A second feedback path, typically a pair current mirrors, serves as a bias loop having unity gain. The bias loop provides a bias current that is responsive to the control current. This device has the advantage of being self biasing, thus no other biasing circuitry is required.

摘要: A voltage-controlled oscillator (VCO) comprising an odd number of delay stage circuits. Each delay stage circuit operates between supply voltages VDD and VSS (VDD>VSS) and comprises (1) an input node, (2) an output node, (3) an inverting circuit, and (4) an electric discharge path coupling the output node to VSS. The electric discharge path includes a switch circuit and a resistance adjusting circuit electrically coupled in series between the output node and VSS. In response to an input signal rising at the input node, the inverting circuit decreases an output signal at the output node, and the electric discharge path opens to help pull the output signal down faster. In response to an input signal falling at the input node, the inverting circuit increases the output signal at the output node, and the electric discharge path closes to minimize its own effect.
