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

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

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 portablebetween different targets

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.

10

MISRA C support

• MISRA C – Defined set of rules describing how to develop ”safe” C from Motor Industry Software Reliability Association (MI SRA)

• 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)

11

Extended Embedded C++

• Adaption of C++ to the specific requirements of embeddedapplications

• 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 weresimple sequences like an array

12

C-SPY® Debugger (1/3)

• Complex code and data breakpoints with new breakpoint category―Log breakpoint

• 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

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 windowswith 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

14

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.

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
