28、nt 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 DOs. APE is reactive. Any computations are started if all input DOs ar
29、e 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 APE in the case of eRVM or mapped to a corresponding APE or RVM/eRVM i
30、n 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 operator computations are written in connected output data if they ar
31、e 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 allocated in the infinite and flat memory. Any RVM has access to this memory.
32、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-time for each APE required executing the given operation NOTE 1: The reso
33、urces 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 dynamic resource sharing. native radio library: library providing plat
34、form-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 can be registered as new SFBs NOTE: Any suitable organization can take
35、 the role of a Radio Library Authority. The choice of the organization is beyond the scope of the present document. 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
36、 is used. Radio Virtual Machine (RVM): abstract machine that supports reactive and concurrent executions NOTE: A RVM may be 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 eff
37、orts. Radio Virtual Machine Runtime Environment (RVM RE): software that allows running Radio Applications that might be Configcodes or executable codes ETSI ETSI TS 103 146-4 V1.1.1 (2017-01)7 Software Intermediate Representation (SWIR): RA representation as data flow chart NOTE: SWIR file contains
38、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 other interruption NOTE 1: Furthermore, terminal operation cannot be decom
39、posed 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 hierarchy and they can be part of another operation. 3.2 Abbreviations For th

All Radio Applications (RAs) are called Unified Radio Applications (UR
45、As) 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 Communication Services Layer (CSL), Radio Control Framework (RCF), Radio Platform and 4 sets of interfaces for their interconnection. Figure 4.1:
46、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 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 an
47、d uniform production of RAs. The present document defines RPI.
