2 Mission Favorire la conoscenza e la diffusione delle tecnologie innovative, creare casi di utilizzo che rendano evidente il valore della piattaforma Microsoft. Iniziative e attività: La redazione dei contenuti sul sito MSDN Italy. Newsletter e Webcast registrati Seminari e conferenze Incontri presso le aziende http://www.microsoft.com/italy/msdn/contattaci/default.mspx

3 Piccoli dispositivi elettronici controllati da microprocessori sono sempre più diffusi ma: Pochi tool ne supportano lo sviluppo Richiedono forti skill per fare cose semplici Sono realizzati con codice unmanaged Microframework si propone per il mondo embedded come VB6 per lo sviluppo delle vecchie applicazioni desktop.

4 MF è un.Net Runtime piccolo per processori embedded 32bit, economici e a basso consuno Ha Memory footprint ridotto (~256K RAM) Non richiede Memory Management Unit Permette lo sviluppo embedded con Visual Studio 2005 Lambiente Include un emulatore completo e funzionale Permette lo sviluppo con linguaggio C# e.Net framework Esegue codice managed controllato e sicuro

8 Microframework è: Bootable Può eseguire boot autonomamente Può essere ospitato su sistemi operativi esistenti Safe Laccesso alle risorse avviene tramite oggetti Secure Utilizza assemblies firmati Extensible A livello software ed Hardware Portable Il Porting Kit permette di portarlo su HW non supportato

9 Runtime grafico Windows Presentation Foundation (WPF): Graphics primitives BMP and JPG image support Text manipulation Unified Programming model covering All devices Runtime engine: Thread support Garbage collection Globalized language support Funzioni di interazione con lhardware Managed drivers for LCDs Universal Asynchronous Receiver/Transmitter (USART) I2C General-purpose I/O (GPIO) Pulse-Width modulation (PWM)

10 Microsoft Visual Studio 2005 Project System/templates PostBuild processing Intellisense support Deployment to device (seriale, usb o emulatore) Debugging interattivo dallIDE (Breakpoints, tracing, variable inspection) Device Emulator Personalizzabile per simulare la configurazione delle periferiche

19 Implementa un sottoinsieme delle core libraries Permette diversi linguaggi di programmazione Rispetta Common Language Specification (CLS) Derivato da Common Language Infrastructure (CLI) v1.0 Supporta Common Intermediate Language (CIL) Execution.

20 Serialization: Implementazione specifica per mf 60% più efficiente in spazio rispetto a.Net Framework Remote Procedure Call (RPC) Implementazione specifica per mf Permette di invocare metodi su oggetti remoti Encryption: Supporta RSA algorithm (Asymmetrico) tramite la classe Key_RSA. supporta Extedned Tiny Encryption Algorithm (XTEA, symmetric) tramite la classe Key_TinyEncryptionAlgorithm. Permette algoritmi custom derivando dalla classe Key. Delegates: permette programmazione ad eventi invece che per polling. Exception handling Reflection

21 Funzioni disponibili includono: Numeric types, class types, value types, arrays (one-dimensional only), delegates, events, references, and weak references Synchronization, threads, and timers Reflection Serialization Garbage collection Exception handling Time classes, including DateTime and TimeSpan (using INT64 arithmetic) Time-sliced thread management Funzioni progettate per microframework: Execution constraints that limit call durations and prevent failures. Strings represented internally as UTF-8 and exposed as Unicode. A global, shared string table for well- known values (types, methods, and fields) that reduces RAM and ROM and reduces the number of cross-references among assemblies. method resolution no virtual tables. A WeakDelegate class to handle dangling references to delegates. Support for extending the hardware chipset by programming its drivers directly in C#, using the Managed Drivers Framework. Hardware devices compatible with industry communication standards such as GPIO, serial, SPI, or I2C can be added to the chipset and used by a managed C# application.

22 Add the clock and other trip control features to the TripComputer

23 Object model Basato su Windows Presentation foundation (WPF) Supporta routed events e context properties Supporta layout system (content sizing, text flow, nested controls) Supporta bitmap fonts Gestisce Images Gestisce Pens, brushes, colors Gestisce Vector primitives Gestisce Alpha blending

24 Permette il boot del runtime Permette una astrazione delle risorse Gestisce gli interrupts Supporta asynchronous cooperative multi-tasking. È realizzato tramite queued Workitems È compatto (Occupa 40K inclusi i base drivers)

25 Assembly loader esegue validazione al caricamento degli assemblies. registra i tipi con il type system (in tabella globale dei tipi) Microsoft Intermediate Language (MSIL) interpreter Supporta TUTTE le msil instructions (tranne le istruzioni unsafe) È ottimizzato per minimizzare la latenza Permette esecuzione virtuale pura

26 Execution engine: No native thread scheduler Manages native work queues Invokes native code Permette non traditional interoperability Garbage collector Non incremental Mark and Sweep. Colleziona 50ms per 1M, variabile a seconda del numero di oggetti Supporto per storage non volatile. dispone di un meccanismo di persistenza di oggetti
