29、itions and abbreviations 3.1 Definitions For the purposes of the present document, the following terms and definitions apply: Abstract Processing Element (APE): abstracts computational resource that executes any computations downloaded from Radio Library NOTE: APE is connected with input and output
30、DOs. APE is reactive. Any computations are started if all input DOs are filled with real data. basic operations: operations either provided by the Radio Library and/or UDFB Set to eRVM or by the Radio Library and/or RVM/eRVM Configcodes to RVM NOTE: Each Basic Operation is mapped to a corresponding
31、APE in the case of eRVM or mapped to a corresponding APE or RVM/eRVM in the case of RVM. data flow chart: reactive data flow computational model consisting of data and operators where data are connected with operators NOTE: Operators abstract computations. They are triggered by full data. Results of
32、 operator computations are written in connected output data if they are empty. Data Object (DO): typeless token abstracting any type of data NOTE: DO provides a container for storing data. It can be empty if no data in the container or it can be full if there is data in the container. DO is allocate
33、d in the infinite and flat memory. Any RVM has access to this memory. One or a few APEs from RVM can be connected with DO. DO acknowledges connected APEs about its status whether it empty or full. dynamic operation: operation that is performed by allocating the computational resources during run-tim
34、e for each APE required executing the given operation NOTE 1: The resources are deallocated upon completion of the corresponding operation. NOTE 2: Dynamic operation is available only in the case of MDRC-7 defined in ETSI EN 302 969 1. In other words, dynamic operation is needed when RA requires the
35、 dynamic resource sharing. native radio library: library providing platform-specific description of each SFB that represents the target platform hardware port configuration: specification of the number of APEs inputs and outputs radio library authority: authority empowered to decide which components
36、 can be registered as new SFBs NOTE: Any suitable organization can take the role of a Radio Library Authority. The choice of the organization is beyond the scope of the present document. Radio Virtual Machine (RVM): abstract machine that supports reactive and concurrent executions NOTE: A RVM may be
37、 implemented as a controlled execution environment that allows the selection of a trade-off between flexibility of base band code development and required (re-)certification efforts. Radio Virtual Machine Runtime Environment (RVM RE): software that allows running Radio Applications that might be Con
38、figcodes or executable codes reference radio library: library providing normative definition of each SFB NOTE: There may be multiple such Reference Radio Libraries. For a given RA, a unique Reference Radio Library is used. ETSI ETSI EN 303 146-4 V1.1.2 (2017-04) 7 Software Intermediate Representatio
39、n (SWIR): RA representation as data flow chart NOTE: SWIR file contains information on all terminal objects, their parameters (cost, implement function, size, etc.) and connections (links, access type, source and destination). terminal operation: operation that will always be executed without any ot
40、her interruption NOTE 1: Furthermore, terminal operation cannot be decomposed into smaller operations. NOTE 2: “Terminal operations“ are equivalent to “atomic operations“, but additionally it indicates that a hierarchy is being used in which the “terminal operations“ are on the lowest level of hiera
41、rchy and they can be part of another operation. 3.2 Abbreviations For the purposes of the present document, the following abbreviations apply: AOT Ahead-Of-Time APE Abstract Processing Element ASF Abstract Switch Fabric CC Configcodes Counter CSL Communication Services Layer CU Control UnitDO Data O

46、e set of radios by loading new Radio Application Package (RAP). All Radio Applications (RAs) are called Unified Radio Applications (URAs) when they exhibit a common behaviour from the reconfigurable MDs point of view i.2. In order to run multiple URAs, the reconfigurable MD will include Communicatio
47、n Services Layer (CSL), Radio Control Framework (RCF), Radio Platform and 4 sets of interfaces for their interconnection. Figure 4.1: Four sets of interfaces for Reconfigurable MD Figure 4.1 illustrates the Reconfigurable MD architecture with the 4 sets of interfaces, i.e.: MURI for interfacing CSL
48、and RCF i.2; RRFI for interfacing URA and RF Transceiver i.3; URAI for interfacing URA and RCF i.2; RPI for allowing an independent and uniform production of RAs. The present document defines RPI.
