Abstract: A method and system are described that support proper operation of RTSA by providing it the required real-time resources at the right time. The method and system include three elements: Isolation, Independence, and Timing limited/non-blocking interfaces. Isolation defines to the host operating system and any other element involved that the CPU core or few CPU cores that are used to run the RTSA should be isolated, be in full ownership of the RTSA, and cannot serve any general purpose task of the platform. Independence is an attribute or characteristic that the code used in the RTSA preferably does not use any external service/device unless the service/device has a clear known deterministic real-time characteristic. Timing limited/non-blocking interfaces is an attribute or characteristic that, in cases where interfaces between the RTSA to other software program is needed, the interface should preferably be limited in effecting the timing operation of the RTSA.

Abstract: A chip architecture for use in processing signals encoded in accordance with any one of a plurality of communication protocols each defined by a series of algorithms is disclosed. The chip architecture comprises a plurality of megafunctions, each in the form of reusable, reconfigurable functional blocks for use in implementing different algorithms necessary for implementing the physical layer of each of the communication protocols; and a plurality of switches configured to respond to select control signals so as to interconnect the necessary megafunctions for processing the signals encoded with each of the protocols. Preferably, at least some of the same megafunctions are used with algorithms of two or more protocols.

Abstract: A chip architectural core is described for use in decoding one or more vectors received by the core in accordance with one or more recursive and/or non-recursive systematic trellis codes of varying sizes and constraints K, as well as generator polynomials. The core comprises: a decoder including (a) a reconfigurable network of ACS blocks, BMU generators and trace-back mechanisms for both recursive and non-recursive systematic forms, and (b) reconfigurable connections between the ACS blocks, BMU generators and trace-back mechanisms, arranged so that the precise number of network components can be continuously rearranged and interconnected in a network as a function of size and the constraint K and generator polynomial of each code used for encoding the vectors received by the core.
