1 IAR Embedded Workbench for 8051 Version 7.30A 1

2 Highlights in version 7.30 More efficient banked memory model Support files for many new devices added - complete list at Supportfiles for many new devices added New and updated example applications 2

3 Modular and Extensible Architecture IAR Embedd Workbench IDE Custom plug-ins (editors, source code control systems, etc.) Text editor Project manager C/C++ compilers assembler C-SPY debugger Simulator HW systems plug-ins IAR ROM-monitor Analog Devices ROMmonitor Chipcon JTAG interface Infineon Debug Access Server (DAS), etc Linker, libraries RTOS plug-ins OSEK ORTI 3

4 Easy-to-use IDE Powerful Project Manager can arrange multiple projects in a workspace Smart Source Browser - Easy navigation to functions, types, variables and macros and with filtering possibilities Improved context-sensitive help Open architecture allows easy expansion of the standard tool chain External editor Source code control system integration 4

5 Powerful Project Manager can arrange multiple projects in one workspace Source Browser for quick navigation to function/variable definitions and declarations Setting breakpoint, editing while debugging View registers in groups 5 Docking windows, multiple views

6 A Flying Start Ready-made chip I/O register definition files for over 350 chips Project templates for C, C++ and assembler projects Sample projects for various evaluation boards Comprehensive documentation with efficient coding hints Context-sensitive online help with library function and keyword lookup 6

7 IAR C/C++ Compiler Highly optimized ISO/ANSI standard C/C++* compiler Customizable C/C++* library, pre-built and in source form Comprehensive language extensions allow detailed tailoring of embedded applications Flexible segment commands allow detailed control of code and data placement Multiple levels of optimizations for code size and execution speed Major functions of the optimizer can be controlled individually, for example loop unrolling 7

8 8051-Specific Compiler Support Multiple code and data models, (where applicable) Extensive set of language features for PROMable embedded code, including memory keywords, intrinsic functions, interrupt functions, memory-mapped I/O ports, etc. User control of register usage for optimal performance Support for DATA, IDATA, XDATA, PDATA and BDATA Support for multiple DPTR in compiler and libraries Bitwise addressing for SFRs Possibility to use up to 32 virtual registers Highly optimized reentrant code models make the project portable between different targets 8

9 Compiler Design For optimal performance, each code model combines the reentrant calling convention with static overlay depending on data model chosen. Usage of virtual registers to lower the register usage pressure. Generic pointers will not be default in any libraries. Support for multiple data-pointers. Flexible on the command line to make configuration easy from IDE. A design that covers most extended 8051-derivatives known today. 9

10 MISRA C support MISRA C Defined set of rules describing how to develop safe C from Motor Industry Software Reliability Association (MISRA) MISRA C checker Rule-checking and logging Covers automatic checking of 101 of 127 rules Several un-covered rules require manual checking Comprehensive documentation (IAR Embedded Workbench MISRA C Reference Guide) 10

11 Extended Embedded C++ Adaption of C++ to the specific requirements of embedded applications Support for C++ templates, namespaces, mutable specifier, static cast, reinterpret cast and const cast Multiple inheritance and virtual inheritance All required ISO/ANSI C libraries and extended C/EC++ library available, including Standard Template Library (STL) STL Container Awareness in C-SPY gives a unique overview of elements in STL container data types; the contents of complex collections like lists and maps can be displayed as if they were simple sequences like an array 11

12 C-SPY Debugger (1/3) Complex code and data breakpoints with new breakpoint category Log breakpoint True editing-while-debugging Very fine granularity execution control (function call-level stepping) Stack window to monitor the memory consumption and integrity of the stack Runtime backtrace via C call stack Profiling and code coverage performance analysis tools Trace utility with expressions to examine execution history 12

13 C-SPY Debugger (2/3) Versatile monitoring of registers, structures, call chain, locals, global variables and peripheral registers Smart STL container display in Watch window Symbolic memory window showing memory content annotated with global symbols Static watch window showing global and static variables, including function and class statics Convenient file/function/variable accessing in different windows with Drag and drop model RTOS-aware debugging via OSEK Run-Time Interface (ORTI) plug-in for any ORTI-compliant OS C-SPY Debugger plugin SDK available for 3rd party debuggers 13

14 C-SPY Debugger (3/3) The C-SPY Debugger supports the following HW target systems: Configurable IAR ROM-monitor for the NXP LPC935, TI MSC1211 Analog Devices ROM-monitor for the ADu83x, ADu84x and ADE7169F16 devices Chipcon JTAG interface for the Chipcon CC2430 SoC ZigBee development kit Infineons Debug Access Server (DAS) for the Infineon XC8xx device family Manley Electronics ME52HU emulator Silicon Laboratories USB and serial (EC2) JTAG adapters Generic IAR ROM-monitor project template included for user reconfiguration for additional 8051 boards and kits 14

15 Fine grained single stepping on function call level Easy simulation of interrupts Extensive online help Call stack information Profiling and code coverage helps you to analize your application and locate the bottle-necks 15

16 Extensive hardware debugging support RTOS-awareness debugging Extensive output format support 16

18 Benchmark compared tools IAR Systems: version 7.20 of IAR Embedded Workbench for 8051 (EW8051) using the xdata reentrant calling convention which is fully compatible with the ANSI C standard. Keil Software: version 7.50 of C51 compiler (PK51) using the static overlay calling convention which reduces the size of the generated code but also limits the way functions can be called. 18

19 Benchmark code examples The following code examples are used in this benchmark: embos_test embos (RTOS) from Segger dhry Standard benchmark decrypt Decrypt algorithm patricia MiBench image recognition package 19
