System and Method for Elastic Despreader Memory Management

摘要

The disclosure is directed to a system and method of managing memory resources in a communication channel. According to various embodiments, incoming memory slices associated with a plurality of data sectors are de-interleaved and transferred sequentially through a buffer to a decoder for further processing. To prevent buffer overflow or degraded decoder performance, the memory availability of the buffer is monitored, and transfers are suspended when the memory availability of the buffer is below a threshold buffer availability.

主权项

1. A communication channel, comprising:
a despreader memory block configured to de-interleave incoming memory slices associated with a plurality of data sectors; a buffer configured to receive the de-interleaved memory slices and further configured to transfer the de-interleaved memory slices of the plurality of data sectors sequentially to a decoder for further processing; and a resource management controller configured to monitor a memory availability of the despreader memory block and a memory availability of the buffer and further configured to prevent the despreader memory block from transferring the de-interleaved memory slices of a data sector to the buffer when the memory availability of the buffer is below a threshold buffer availability and the memory availability of the despreader memory block is above a threshold despreader availability.
