摘要： A wireless communication system hosts a plurality of processes in accordance with a communication protocol. The system includes application specific instruction set processors (ASISPs) that provided computation support for the process. Each ASISP is capable of executing a subset of the functions of a communication protocol. A scheduler is used to schedule the ASISPs in a time-sliced algorithm so that each ASISP supports several processes. In this architecture, the ASISP actively performs computations for one of the supported processes (active process) at any given time. The state information of each process supported by a particular ASISP is stored in a memory bank that is uniquely associated with the ASISP. When a scheduler instructs an ASISP to change which process is the active process, the state information for the inactivated process is stored in the memory bank and the state information for the newly activated process is retrieved from the memory bank.

摘要： An architecture and method for flexible preamble processing is disclosed herein. The preamble processing engine detects a code sequence in input, where the code sequence is a sum of a first code sequence and a second code sequence The preamble processing engine includes a data input line, a code input line, a despreader, and a plurality of memory registers. The code input selectively receives the first code sequence or the second code sequence, the first code sequence having a period longer than a period for the second code sequence. The despreader is coupled to the data input line and the code input line. The despreader producing a despread result between the first code sequence and the input data. Lastly, the plurality of memory registers, which are coupled to the despreader, each stores only a portion of the despread results.
