1. A transceiver comprising:
- a transmitter portion operable to transmit a first message over a channel, wherein the first message indicates a first maximum number of bytes associated with an interleaver function of a transmit latency path and a first maximum number of bytes associated with a deinterleaver function of a receive latency path; and
a receiver portion operable to determine a change in a channel condition for the channel;
the transmitter portion further operable to transmit a second message over the channel after determining the change in the channel condition, wherein the second message indicates a second maximum number of bytes associated with the interleaver function of the transmit latency path and a second maximum number of bytes associated with the deinterleaver function of the receive latency path,wherein the first maximum number of bytes associated with the interleaver function of the transmit latency path is different than the second maximum number of bytes associated with the interleaver function of the transmit latency path, andwherein the first maximum number of bytes associated with the deinterleaver function of the receive latency path is different than the second maximum number of bytes associated with the deinterleaver function of the receive latency path.

Abstract
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.

4. A transceiver comprising:
-
a transmitter portion operable to transmit a first message over a channel at a first time, wherein the first message indicates a first maximum number of bytes associated with an interleaver function of a transmit latency path and a first maximum number of bytes associated with a deinterleaver function of a receive latency path; and a receiver portion operable to determine a change in a channel condition of the channel, wherein the transmitter portion is further operable to transmit a second message over the channel at a second time after determining the change in the channel condition, wherein the second message indicates a second maximum number of bytes associated with the interleaver function of the transmit latency path and a second maximum number of bytes associated with the deinterleaver function of the receive latency path, wherein the first maximum number of bytes associated with the interleaver function of the transmit latency path is different than the second maximum number of bytes associated with the interleaver function of the transmit latency path, wherein the first maximum number of bytes associated with the deinterleaver function of the receive latency path is different than the second maximum number of bytes associated with the deinterleaver function of the receive latency path, wherein the first time is different than the second time, and wherein one or more bytes of memory is used by the interleaver function of the transmitter portion at the first time and the same one or more bytes of the memory are used by the deinterleaver function of the receiver portion at the second time.

5. In a transceiver, a method comprising:
-
transmitting, by a transmitter portion over a channel, a first message, wherein the first message indicates a first maximum number of bytes associated with an interleaver function of a transmit latency path and a first maximum number of bytes associated with a deinterleaver function of a receive latency path; determining a change in a channel condition of the channel; and transmitting a second message, by the transmitter portion over the channel, after determining the change in the channel condition, wherein the second message indicates a second maximum number of bytes associated with the interleaver function of the transmit latency path and a second maximum number of bytes associated with the deinterleaver function of the receive latency path; wherein the first maximum number of bytes associated with the interleaver function of the transmit latency path is different than the second maximum number of bytes associated with the interleaver function of the transmit latency path, and wherein the first maximum number of bytes associated with the deinterleaver function of the receive latency path is different than the second maximum number of bytes associated with the deinterleaver function of the receive latency path. - View Dependent Claims (6, 7)
