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.

International Classification:

G02F001/00
G02B006/26
H01L021/44

US Classification:

359321, 359322, 385 27, 438615

Abstract:

The present invention is directed to a method for enhancing functionality for photonic devices each including at least one operable surface. This method includes stacking the photonic devices such that each of the operable surfaces are aligned to form a composite surface, applying a film adapted to receive a replication to the composite surface and replicating a pattern of nanostructures in the applied film. Substantially, each of the operable surfaces is replicated with a sufficient portion of the replicated pattern of nanostructures to enhance operation of the devices by performing a given function associated with the nanostructures.

International Classification:

G02B006/10

US Classification:

385129, 359332

Abstract:

A wavelength tunable device for operating on at least a portion of energy propagating through a waveguide is disclosed. The wavelength tunable device includes an upper cladding and a lower cladding having a core substantially disposed there between and suitable for optically coupling to the waveguide, a pattern of nanostructures positioned substantially on the upper cladding distal to the core so as to define a reflectivity for energy propagating through the waveguide, and, a movable membrane aligned with the pattern of nanostructures so as to at least partially define a gap there between. This gap may be selectively controlled upon actuation of the movable membrane so as to cause a corresponding change in the reflectivity.

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.
