  • Patent number: 6782611
    Abstract: A method of assembling a multi-chip device may include coupling solder balls only to selected ones of the conductive pads on an interposer with cache memory devices.

  • Patent number: 5864478
    Abstract: A power delivery system includes a circuit board, a power consuming module and a dc--dc converter. The printed circuit board has on it a first signal connector, a pair of first contacts to which a first voltage is supplied, spaced from said connector, and fasteners spaced from said pair of first contacts. The power consuming module has a second signal connector, mating with the first signal connector, and has respective upper and lower power pads for receiving low voltage power. The dc--dc converter converts the first voltage to a lower voltage. The dc--dc converter has a pair of second contacts contacting said pair of first contacts, surfaces mating with said fasteners and holding the converter on the printed circuit board such that said second contacts are in firm contact with said first contacts, and a laterally extending connector having upper and lower contacts supplying the lower voltage and engaging the upper and lower power pads of the power consuming module.

  • Patent number: 5115455
    Abstract: Data can be accurately transmitted between two subsystems in a synchronous system even if the clock skew or propagation delay between the two subsystems is greater than one clock cycle time. The source and destination subsystems are initialized to ensure synchronous operation. The source subsystem transmits data and a forwarded clock to the destination subsystem. The forwarded clock is passed through a delay device to introduce a one-half cycle delay into the forwarded clock timing. Data is captured in three state devices arranged in parallel to eliminate minimum delay requirements and to expand data valid time. The captured data is then aligned to the destination subsystem's clock by controlling a multiplexer which selects the proper signal at its input to pass to the input of a second state device coupled to its output. The data selected is then clocked into the second state device under the control of the distination subsystem's clock, thus aligning the received data with the destination subsystem's clock.

  • Patent number: 5072132
    Abstract: A VSLI circuit includes a plurality of state device circuits on a VLSI chip. Each of the state device circuits includes a latch and is clocked by a pulse generator circuit which produces narrow pulses that are coupled to the clock input of the latch. The narrow pulses have a pulse width substantially equivalent to the propagation delay through the latch of the state device circuits. By taking advantage of the high correlative percentages of devices on portions of the chip, master-slave flip flops can be implemented using only a single latch with a pulse generator.

  • Patent number: 4979190
    Abstract: Data can be accurately transmitted between two subsystems even if the clock skew between the two subsystems is larger than one clock cycle by the method of the invention. In one embodiment data is loaded into N state devices in the sending subsystem while the receiver recovers data from the sending state devices in rotation with an N input multiplexer. Another embodiment forwards a clock signal from the sending subsystem along with a data vector of N state signals for recovery by a pair of state devices capturing data on the rising and falling edges of the forwarded clock. A further embodiment achieves double bandwidth by forwarding two clock signals.

  • Patent number: 4748644
    Abstract: A clock apparatus provides variable frequency system clock signals for synchronizing the operation of data processing apparatus and constant frequency timing signals, in phase with the system clock signals, for controlling the operation of an interval timer or related apparatus. The variable frequency system clock signals are produced by placing a controllable divider network in the phase locked loop. The input signals to the controllable divider network are distributed as the system clock signals. The constant frequency is obtained by distributing count signals from the controllable divider network of the phase locked loop circuit to a plurality of comparator circuits and output signals from the comparator provide a multiplicity of timing intervals that result in the constant frequency signals. The timing intervals are determined by the control signals that are applied to controllable divider network and to a plurality of divider circuits associated with the comparator circuits.
