Method and system for data packer unit for accelerating stack functions

摘要

Methods and systems for data packer unit for accelerating stack functions may include packing payload bits for HSDPA packets in sequence, in hardware, for example, a multistage pipeline, to form a data packet. The data packet may be aligned to start on a n-bit boundary, regardless of a bit position of the start of one or more of the payloads. The value of n may be a multiple of 8, such as, for example, 32. Bits, which may be zeros, for example, may be inserted to end of the data packet to pad the data packet to an n-bit boundary. The HSDPA packets may be fetched from memory, for example, by using variable burst DMA. The information to fetch the HSDPA packets may be stored, for example, in a linked list. The operation of packing the payloads from the fetched HSDPA packets may be controlled via a state machine.
