Filed:

Mar 13, 2000

Appl. No.:

09/523747

Inventors:

Wenwei Pan - Ocean NJ
Jian Wang - Morganville NJ

Assignee:

GlobespanVirata, Inc. - Red Bank NJ

International Classification:

G06F 1100

US Classification:

714701, 714784

Abstract:

A resource optimized interleaving/deinterleaving system comprising a Reed-Solomon encoder, a Reed-Solomon decoder, a state machine, and a memory is disclosed. Reed-Solomon encoded fastpath data is stored in memory. A stream of interleaved data with predefined parameters S, the number of DMT symbols per each Reed-Solomon codeword, D, the interleaving depth, and N, the block length is written into system memory at an adaptable rate determined by the Reed-Solomon encoder. The previously stored Reed-Solomon encoded fastpath data is automatically reassembled and buffered with the interleaved data to form appropriate DMT transmission symbols. The DMT transmission symbols are then read out of the system memory at a rate determined by the next processing function, i. e. , tone ordering. A method of using one Reed-Solomon encoder/decoder with the integrated interleaving/deinterleaving system to support dual single latency DMT systems is also disclosed.

International Classification:

H03M 1327

US Classification:

714701

Abstract:

A circuit and method that provides a one-step real time pointer for interleaving/deinterleaving that uses a single modulo operation is disclosed. The single modulo pointer of the present invention may be used to increase data throughput through a data interleaver/deinterleaver. A memory address pointer consistent with the present invention may be implemented with a multiplexer, an adder, a counter, and a modulo operator. A method for convolutional interleaving/deinterleaving is also disclosed.

Assignee:

Visteon Global Technologies, Inc. - Dearborn MI

International Classification:

B60G 1110

US Classification:

280124175, 280124148, 28012417, 267227

Abstract:

An independent rear suspension for a motor vehicle chassis includes a pair of independent rear corner modules. Each rear corner module includes a generally-longitudinally-extending leaf spring whose forward end is adapted to be pivotally mounted to the vehicle chassis at a first forward attachment point, and whose rearward end is nonrotationally-coupled to a knuckle, such that the leaf spring operates as a trailing arm to longitudinally position the knuckle relative to the chassis. A shackle adapted to be pivotally mounted on the chassis at a second forward attachment point includes an eye that encompasses a portion of the spring intermediate the first and second end of the spring. The shackle permits a predetermined, nonzero range of relative longitudinal, transverse, and torsional movement of the intermediate portion of the leaf spring while otherwise transferring vertical loads from the intermediate portion of the spring to the chassis.

International Classification:

US Classification:

714788, 714702, 714762

Abstract:

A memory optimized system and method for data interleaving/de-interleaving are disclosed. A data interleaver/de-interleaver may be implemented with a memory device and an improved data interleaver/de-interleaver. The improved data interleaver/de-interleaver may be implemented with a controller, a first array, and a second array. The first array identifies a maximum depth value for each of a plurality of memory segments responsive to both a block data length and the desired interleaving/de-interleaving depth. The second array comprises an index associated with each of the plurality of memory segments that may be used to derive write and read addresses. In its broadest terms, the method can be described as: identifying a block data length, N, and an interleaver/de-interleaver depth, D; initializing a set of pointers associated with each of N memory segments; initializing a set of pointer maximum values responsive to the relative magnitude of N and D, identifying a memory index responsive to a base address and the set of pointer maximum values; using a memory segment identifier, a word identifier, and a byte identifier along with the memory index and the pointers to write/read the bytes of code words.

US Classification:

372 18, 372 92, 372102

Abstract:

In accordance with the invention, a mode-locked laser comprises an optical gain medium disposed within an optical cavity formed by a first reflector and a wavelength selective second reflector to achieve mode-locking operation. Advantageously, the wavelength reflective reflector is a two-dimensional subwavelength resonant grating. The resulting laser is compact, tunable, reliable and inexpensive. It provides high side mode suppression and high output power.
