Low-Power, Glitch-Less, Configurable Delay Element
Fulong Zhang - Upper Macungie PA, US Zheng Chen - Upper Macungie PA, US Chien Kuang Chen - San Jose CA, US John Schadt - Bethlehem PA, US
Assignee:
Lattice Semiconductor Corporation - Hillsboro OR
International Classification:
H03H 11/26
US Classification:
327277, 327262, 327284
Abstract:
In one embodiment, a configurable delay element has three stages. The first stage has an 8-buffer first delay chain and an (8×1) first mux that selects one of the eight first-delay-chain outputs. The second stage has a 24-buffer second delay chain connected to receive the first-mux output and organized into three 8-buffer sub-chains and a (4×1) second mux that selects one of the four second-delay-chain outputs. The third stage has a 96-buffer third delay chain connected to receive the second-mux output and organized into three 32-buffer sub-chains and a (4×1) third mux that selects one of the four third-delay-chain outputs as the delay-element output signal. A delay-element controller provides glitch-less updates to the signal used to control the delay-element muxes by timing those updates to occur when all delay-element buffers have the same state. The controller bases the update timing on the delay-element output signal.

International Classification:
H03L 7/06
US Classification:
327156, 327159, 375376
Abstract:
A frequency synthesizer is configured to generate a periodic output signal in response to a periodic input signal and a temperature-dependent frequency adjusting control signal. A temperature sensor is provided, which is configured to generate a temperature measurement signal in response to detecting a temperature of at least a portion of the frequency synthesizer. A control circuit is provided, which is configured to generate the temperature-dependent frequency adjusting control signal in response to the temperature measurement signal. This control circuit includes a cascaded arrangement of an oversampled data converter and a multi-stage digital filter, which is configured to generate a plurality of codes from respective ones of the digital filter stages, and a selection circuit, which is configured to use at least first and second ones of the plurality of codes in sequence during first and second consecutive time intervals to generate the temperature-dependent frequency adjusting control signal.

Abstract:
An interconnect device for transmitting data packets includes a plurality of ports, a hub, and an arbiter. The hub is configured to connect the plurality of ports together. The arbiter is coupled to the hub for controlling transmission of data packets between the hub and the ports. A reset is provided in at least one of the ports. The reset is in communication with the arbiter such that arbiter can reset the port in response to a detected error in the port.
Merging Data Using A Merge Code From A Look-Up Table And Performing Ecc Generation On The Merged Data
A system and method providing ECC protection for all data block sizes for which a computer system supports store (ST) accesses includes an access control logic unit which converts store accesses for small data block (. ltoreq. 64-bits) into read-modify (merge)-write accesses and a data merge logic unit which merges 64-bit data blocks retrieved by the load access with the small data block of the store access to create a new 64-bit data block. The data merge logic unit utilizes a merge code provided from a look-up table in a programmable logic array to perform the merging of the data blocks. An ECC generation logic unit processes the merged 64-bit data block, including the new small data block.
