    摘要: A flash-memory-card reader reads and writes multiple types of flash-memory cards, including CompactFlash, and the smaller SmartMedia, MultiMediaCard, Secure Digital, and Memory Stick. A converter chip converts the different card signals for transfer to a host personal computer (PC). Serial-to-parallel data conversion is performed for the smaller card formats with serial data interfaces, but not for CompactFlash with a parallel-data interface. A signal slot has a 50-pin connector for CompactFlash cards or passive adapters. The passive adapters have the CompactFlash form factor and a smaller connector fitting smaller flash cards. Passive adapters have no components but simply wire the smaller connector to the CompactFlash connector. A pin mapping allows card-type detection by sensing the LSB address pins of the CompactFlash interface. A larger CompactFlash reader has multiple slots for each card type. The reader is connected to the PC by a cable, or located within the PC chassis in a drive bay. A stand-alone reader copies images from the flash-memory card to a removable disk media. Pressing a button initiates image transfer.

    摘要: One embodiment of the present invention provides a system that speeds up timing analysis by reusing delays computed for isomorphic subcircuit. During operation, the system receives a circuit block to be analyzed, wherein the circuit block is in the form of a netlist. The system then subdivides the circuit block into a set of subcircuits. The subcircuits are then partitioned into equivalence classes, which contain subcircuits which are topologically isomorphic to each other. Next, the system performs a timing analysis by tracing paths through a timing graph for the circuit block. During this timing analysis, whenever a delay is required for a subcircuit, the system determines if a corresponding delay has been already computed for the equivalence class associated with the subcircuit. If so, the system reuses the delay. If not, the system computes the delay for the subcircuit, and then associates the computed delay with the equivalence class so that the computed delay can be reused for isomorphic subcircuits.

    摘要: A multi-memory media adapter comprised of a first planar element having an upper surface and a lower surface, a second planar element having an upper surface and a lower surface, and formed from a single material. The two planar elements form at least one port, each port capable of receiving one or more types of a memory media card. The adapter has at least one set of contact pins protruding from the lower surface of the first planar element or the upper surface of the second planar element such that the at least one set of contact pins are disposed within the port. The at least one set of contact pins are capable of contacting the contacts of a memory media card inserted into the port. For one embodiment a controller chip is embedded within the single material forming the multi-memory media adapter.

    摘要: The timing of control signals in a parallel port is measured and adjusted to achieve optimum timing of these control signals. At boot-up, a routine writes alternating data to the control register of the parallel port. The control register drives control signal over a parallel-port cable to an external parallel-port device connected to the parallel port of a personal computer (PC). Transitions of the control signal trigger an external timer in the external parallel-port device which measures the pulse width of the control signal. The measured pulse width is sent back to the PC over the parallel cable and compared to a target pulse width. When the measured pulse width is less than the target, additional intervening instructions are inserted between writes to the parallel-port control register. The intervening instructions are a simple delay loop. Alternately the internal timer on the PC may be used. Since the accuracy is less for the internal timer, many IO writes are performed to average out errors. Several external devices having cross-over adapters may be coupled together and addressed separately. Two of the ground signals in the parallel port are used as addressing grounds.

    摘要: A parity generating circuit that can replace the parity bit DRAM on a 9-bit SIMM. The parity generating circuit includes a parity generating tree which outputs the resulting even parity from the 8 data bits on a read. A 9th data input from another parity generator on the system mother board is compared to the generator tree output when DRAM is written to. If a mismatch occurs, the type of parity generated by the generator tree is opposite to the type of parity that the mother board generates, and the parity tree output must be inverted on subsequent reads. A latch is provided to store the compare result, which also indicates the type of parity required, even or odd, on the particular system the SIMM is installed on. The latch is loaded when the DRAM is written to. The state of the latch is used to output the correct type of parity on a read from DRAM by inverting the output of the parity generating circuit if needed. This eliminates the cost of the 9th DRAM chip on the SIMM, yet allows for parity checking of the data paths on the system board traces and any older 9-bit memory present in the system.

    摘要: A cove base for sealing a gap between a wall and a floor using a sealant is provided. The cove base comprises a base configured to extend along a portion of the wall when installed. A shoe extends at an angle from the base and is configured to extend towards the floor and away from the wall when installed. A heel extends from the shoe and is configured to contact the floor when installed. A channel configured to receive the sealant is defined by the space between the heel and the shoe.
