摘要： A system to identify timing differences due to logic block changes, the system may include a controller, and storage in communication with the controller. The controller may provide delay values of a previous logic block and a current logic block. The system may also include a timing-modeler to compare the delay values of the previous logic block with the current logic block for timing analysis. The system may further include an interface that provides a report based upon the previous logic block and the current logic block comparison.

摘要： A system for logic block timing analysis may include a controller, and storage in communication with the controller. The storage may provide delay-versus-conesize values of a logic block. The system may further include a fitting module to provide a delay-cone based upon the delay-versus-conesize values of the logic block. The system may also include a conesize parser that uses the delay-cone to provide delay values through the logic block. The conesize parser may be used to validate the design of the logic block by comparing the delay-cone with a desired cycle time.

摘要： A high-performance gate library is augmented with tapered gates. The widths of the stacked devices are varied to reduce the delay through some of the input pins. For example in a tapered NAND gate the bottom devices in the NFET stack are have longer widths than the top device to achieve smaller top input to output pin delay at the expense of larger bottom input to output pin delay. The method of using synthesis algorithms modifies the input net to gate pin connections and swaps traditional non-tapered gates with tapered gates to improve the delay of the timing critical paths. The latest arriving gate input net is swapped with the net connected to the top pin. The gate is then converted to a tapered gate provided the paths through the bottom gate input(s) that are not timing critical.

摘要： In a computer system comprising a plurality of subsystems, interconnected by a bus comprising bit drivers and bit receivers, data words are transmitted on the bus in the form of code words. The code words are formulated such that the number of bits of the bus which changes with the transmission of successive code words is minimized. A switching code, comprising one or more bits, defines a plurality of mapping codes and a data word to be transmitted is mapped by use of the mapping codes to a plurality of code words. One of the plurality of code words differing from a previously transmitted code word in the least number of bit positions is selected. The selected code words is transmitted, together with a switching code, identifying the mapping from which the transmitted code word was generated. At the receiving end of the bus, the switching code is decoded to identify the mapping used in creating the code word. Using the identified mapping, the original data word is recovered.

摘要： A memory access system for improving memory access when addressing dynamic random access modules (DRAMs). The memory access system includes a main memory and a memory controller. To improve memory access, both the memory controller and the main memory hardware remember the row address of the last access. Macro operation commands for fetch and store contain the last row address. The main memory hardware redrives that row address to the DRAMs after completion of an access, so that the memory controller need not provide a row address to the memory for each command of a command sequence.

摘要： An improved memory system and memory controller which permits simplified memory upgrades in the field. The system includes a memory board with multiple card sockets. As additional cards are added the data cables are distributed among the cards and the memory controller is programmed to coordinate the sequencing of the memory in the cards. Data is transferred between the cards and memory controller via distributively coupled cables. Control and address signals are provided to cards via wires embedded in the memory board from the memory controller. A repowering circuit on each card makes copies of the control and address signals which are sent to other cards through the embedded wires in the board. Data received by a card is stored in memory through steering logic and buffers.

摘要： An improved multiprocessor system of the type including a plurality of processors and an array of memories interconnected by an interrogation logic where the processors have a store-in cache is presented. In such processors the most recent copy of the data does not always reside in the memories but can reside in a processor's cache necessitating cross-interrogation producing system delays. These delays are reduced by a fetch buffer selectively coupled to each memory for holding data before cross-interrogation and other checks are complete.

摘要： A non-buffered, noise-immune transmission gate latch for high performance applications is disclosed. The latch data input circuit contains an additional PFET for pulling up the gate of a transmission PFET and an additional NFET to pull down the gate of the transmission NFET to prevent the transmission gate from inadvertently opening when noise is coupled into the data input node. When data input voltage rises to Vdd+Vtp, the additional PFET begins to turn ON, and an inverted clock node is pulled above Vdd. The higher inverted clock node voltage is coupled to the gate of the transmission PFET and thereby prevents the transmission PFET from inadvertently turning ON. When data input voltage drops to -Vtn, the additional NFET begins to turn ON, and a clock node Is pulled below ground. The lower clock node voltage is coupled to the gate of the transmission NFET and thereby prevents the transmission NFET from inadvertently turning ON. Thus two additional transistors provide the necessary noise immunity.

摘要： A programmable, timing signal generator propagates a digital wave along a delay chain comprised of series connected inverters that has sufficient stages that the edge of the wave will not propagate to the end during one system clock cycle time. The delay chain is sampled once each clock cycle, and the point to which the wave has progressed is encoded. Programmable, fine leading and fine trailing edge registers store, as a fraction of the clock cycle time, the desired locations of the timing signal leading and trailing edge relative to the clock edges.
