US Patent 8276048: Resource sharing in a telecommunications environment

• Title: Resource sharing in a telecommunications environment
• Current Assignee: TQ Delta LLC
• Inventors: Marcos C. Tzannes, Michael Lund
• Filing Date: 2010-10-11
• Issue Date: 2012-09-25
• Abstract: A system for allocating shared memory involves transmitting or receiving a message during initialization that specifies the maximum memory available for an interleaver. The system then determines the memory required by the interleaver to process a first set of Reed Solomon (RS) coded data bytes for transmission at a specific data rate. It allocates a portion of the shared memory to the interleaver for this purpose, ensuring it does not exceed the specified maximum. Simultaneously, the system allocates another portion of the shared memory to a deinterleaver to process a second set of RS coded data bytes received at a different data rate. Both interleaving and deinterleaving operations occur concurrently using their respective allocated shared memory.

Plain-Language Overview of Independent Claims:

• Independent Claim 1: This claim describes a system that manages shared memory within a transceiver. The system either sends or receives a message when it starts up (during initialization) that specifies the maximum amount of memory an interleaver can use. It then calculates how much memory the interleaver actually needs to process data encoded with Reed Solomon (RS) codes for transmission at a certain speed. It allocates the necessary shared memory to the interleaver, ensuring this allocation doesn't go over the stated maximum. At the same time, it allocates another portion of the shared memory to a deinterleaver, which processes incoming RS coded data received at a different speed. Both the interleaver and deinterleaver use their allocated shared memory concurrently.

• Independent Claim 5: This claim is structurally similar to Claim 1 but prioritizes the deinterleaver. It describes a system for shared memory allocation in a transceiver where, during initialization, a message is transmitted or received to specify the maximum memory available for a deinterleaver. The system then determines the memory required by the deinterleaver to process a first set of received Reed Solomon (RS) coded data bytes at a specific data rate and allocates that memory, without exceeding the maximum specified in the message. Concurrently, it allocates a second amount of shared memory to an interleaver to process a second set of RS coded data bytes for transmission at a different data rate. The deinterleaver and interleaver use their respective shared memory allocations simultaneously.
