Resource sharing in a telecommunications environment
A transceiver is designed to share memory and processing power amongst a plurality of transmitter and/or receiver latency paths, in a communications transceiver that carries or supports multiple applications. For example, the transmitter and/or receiver latency paths of the transceiver can share an interleaver/deinterleaver memory. This allocation can be done based on the data rate, latency, BER, impulse noise protection requirements of the application, data or information being transported over each latency path, or in general any parameter associated with the communications system.
1. A device comprising:
a transceiver capable of transmitting a first message over a communications channel, wherein the first message indicates a first portion of memory allocated to at least one interleaver in a first latency path and a second portion of memory allocated to at least one deinterleaver in a second latency path; and
the transceiver further capable of transmitting a second message over the communications channel after a change in conditions of the communications channel, wherein the second message indicates a third portion of memory allocated to the at least one interleaver in the first latency path and a fourth portion of memory allocated to the at least one deinterleaver in the second latency path; and
wherein the size of the first portion of memory allocated to the at least one interleaver is different than the size of the third portion of memory allocated to the at least one interleaver, and
wherein the size of the second portion of memory allocated to the at least one deinterleaver is different than the size of the fourth portion of memory allocated to the at least one deinterleaver.
2. The device of claim 1 , wherein memory is shared between the interleaver and the deinterleaver such that at least one byte of memory used by the interleaver after transmitting the first message is used by the deinterleaver after the second message.
3. The device of claim 1 , wherein the first and second message are initialization messages.
4. The device of claim 1 , wherein the first and second message are Showtime messages.
5. The device of claim 2 , wherein the first and second message are initialization messages.
6. The device of claim 2 , wherein the first and second message are Showtime messages.
7. A method comprising:
transmitting, by a transceiver, a first message over a communications channel, wherein the first message indicates a first portion of memory allocated to at least one interleaver in a first latency path and a second portion of memory allocated to at least one deinterleaver in a second latency path; and
transmitting a second message over the communications channel after a change in conditions of the communications channel, wherein the second message indicates a third portion of memory allocated to the at least one interleaver in the first latency path and a fourth portion of memory allocated to the at least one deinterleaver in the second latency path; and
wherein the size of the first portion of memory allocated to the at least one interleaver is different than the size of the third portion of memory allocated to the at least one interleaver, and
wherein the size of the second portion of memory allocated to the at least one deinterleaver is different that the size of the fourth portion of memory allocated to the at least one deinterleaver.
8. The method of claim 7 , wherein memory is shared between the interleaver and the deinterleaver such that at least byte box of memory used by the interleaver after transmitting the first message is used by the deinterleaver after transmitting the second message.
9. The method of claim 7 , wherein the first and second message are initialization messages.
10. The method of claim 7 , wherein the first and second message are Showtime messages.
11. The method of claim 8 , wherein the first and second message are initialization messages.
12. The method of claim 8 , wherein the first and second message are Showtime messages.
13. A non-transitory computer-readable information storage media having stored thereon instructions, that when executed by one or more processors, cause to be performed a method comprising:
transmitting, by a transceiver, a first message over a communications channel, wherein the first message indicates a first portion of memory allocated to at least one interleaver in a first latency path and a second portion of memory allocated to at least one deinterleaver in a second latency path; and
transmitting a second message over the communications channel after a change in conditions of the communications channel, wherein the second message indicates a third portion of memory allocated to the at least one interleaver in the first latency path and a fourth portion of memory allocated to the at least one deinterleaver in the second latency path; and
wherein the size of the first portion of memory allocated to the at least one interleaver is different that the size of the third portion of memory allocated to the at least one interleaver, and
wherein the size of the second portion allocation of memory allocated to the at least one deinterleaver is different that the size of the fourth portion of memory allocated to the at least one deinterleaver.
14. The media of claim 13 , wherein memory is shared between the interleaver and the deinterleaver such that at least one byte of memory used by the interleaver after transmitting the first message is used by the deinterleaver after transmitting the second message.
15. The media of claim 13 , wherein the first and second message are initialization messages.
16. The media of claim 13 , wherein the first and second message are Showtime messages.
17. The media of claim 14 , wherein the first and second message are initialization messages.
18. The media of claim 14 , wherein the first and second message are Showtime messages.
