1 ARM Microcotroller Developmet Tools The RealView Microcotroller Developmet Kit is the complete software developmet eviromet for all ARM7, ARM9, Cortex -M1, ad Cortex-M3 processorbased devices. It combies the idustry leadig RealView compilatio tools (by ARM) with the Keil µvisio IDE/Debugger, providig developers with a easy to use, feature-rich eviromet optimized for ARM Powered devices. The RealView Microcotroller Developmet Kit (MDK) provides a easy-to-use developmet iterface, with may uique features desiged to help you develop your project quickly ad easily. ave time by usig the Device Database to automatically cofigure device ad project parameters. Beefit from better verificatio by usig the itegrated Device imulator which accurately models more tha 260 ARM Powered devices icludig the ARM istructio set ad o-chip peripherals. RealView Compiler Performace The RealView MDK is based o the ARM RealView compilatio tools, recogized as deliverig the tightest, highest performig code for all ARM-Powered devices. I additio, further code size savigs ca be gaied by selectig the ew MicroLib, which has bee specifically developed ad optimized for embedded systems.

2 µvisio Project Maagmet Each project may cotai multiple target cofiguratios. The project workspace lists source ad header files ad helps orgaize your project. Documet outliig gives you a better overview of your source code. The cofiguratio wizard simplifies editig setup files. Cotext meus provide flexible cofiguratio of all aspects of your project. Double-click o messages to locate the erroeous lie i the source code. Project Cofiguratio The µvisio IDE icorporates a Device Database of supported ARM Powered microcotrollers. I µvisio projects, required optios are set automatically whe you select the device from the Device Database. µvisio displays oly those optios that are relevat to the selected device ad prevets you from selectig icompatible directives. Oly a few dialogs are required to completely cofigure all the tools (assembler, compiler, liker, debugger, ad flash dowload utilities) ad memory map for your applicatio. Project Maagemet File Groups allow you to group associated files together. They may be used to separate files ito fuctioal blocks or to idetify egieers i your software team. Project Targets allow you to create several programs from a sigle project. You may require oe target for testig ad aother target for a release versio of your applicatio. Each target allows idividual tool settigs withi the same project file. Editor ad ource Browser The µvisio Editor icludes all the stadard features you expect i a professioal editor. Workflow is optimized with ituitive toolbars providig quick access to editor fuctios, most of which are also available while debuggig for easy source code chages. The itegrated µvisio ource Browser quickly displays iformatio about symbols ad variables i your program usig the F12 key ad the ource Browser Widow. The ource Browser provides istat details o variable defiitios ad usage. 2 RealView Microcotroller Developmet Kit

3 µvisio Program Debuggig ad imulatio The disassembly widow shows trace itermixed with source code. Code coverage ad profilig iformatio display i the source widow. The toolbox cotais user defiable buttos to ru commads or debug The logic aalyzer shows chages to variables ad sigals over time. ymbol ames may be dragged ad dropped to other debugger widows. Memory ad watch widows display importat program variables. Eter debug commads ito the commad tab of the output widow. Debugger ad Device imulator Aalysis Tools The µvisio Debugger supports complex breakpoits (with coditioal or logical expressios) ad memory access breakpoits (with read/write access from a address or rage).the debugger also displays code coverage ad executio profilig iformatio i the editor widows. The µvisio Debugger provides powerful aalysis tools for fast applicatio developmet, verificatio ad optimizatio. Additioally, the µvisio Debugger simulates a complete ARM Powered microcotroller icludig the istructio set ad o-chip peripherals. These powerful simulatio capabilities provide serious beefits ad promote rapid, reliable embedded software developmet ad verificatio. imulatio allows software testig with o hardware. overall reliability with early software debuggig. imulatio allows breakpoits that are ot possible with hardware debuggers. imulatio allows for optimal iput sigals (hardware debuggers add extra oise). igal fuctios are easily programmed to reproduce complex, real-world iput sigals. igle-step through sigal processig algorithms. Test failure scearios that would destroy real hardware. µvisio provides code coverage statistics for applicatio verificatio. Improve Performace Aalyzer shows executio time for tasks ad programs. 3

4 Hardware Debuggig ad Trace ARM7/9 Debuggig Debuggig of ARM7 ad ARM9 processor-based devices is supported via the stadard 5-wire JTAG iterface usig the Keil ULINK 2 Adapter. Whe used with µvisio, ULINK2 eables you to dowload programs to o-chip ad exteral Flash, set breakpoits, view memory cotets, ad siglestep through your program. Real-Time Aget Debuggig usig JTAG requires the processor to be halted to allow memory modificatios or settig of breakpoits, this is ot always practical i a embedded applicatio. By addig the Keil Real-Time Aget to your applicatio, you are able to view ad modify your target's memory, ad set breakpoits o-the-fly without stoppig your program. erial data commuicatio which would ormally be output via a serial chael ca be displayed i the Real-Time Aget Termial widow. Cortex-M3 Debuggig Cortex-M3 processor-based devices offer a ew erial Wire (W) debug mode, replacig the JTAG iterface with a 2-pi iterface, ad offerig ew features. The erial Wire Viewer (WV) uses oe further pi ad provides Real-Time Trace iformatio about: iterrupt executio, data read/write of selected variables, evet couters, ad user trace data. The Logic Aalyzer ad Trace Records widows display trace iformatio i real-time while the processor cotiues operatig at full speed. The µvisio Real-Time Aget Termial displays serial ad pritf style iformatio which would ormally be output through a o-chip serial chael. For detailed iformatio, refer to Hardware Debuggig usig ULINK2 ULINK2 coects via UB to the target board. It supports JTAG ad erial Wire modes icludig WV Real-Time Trace. Three coector types are supported by ULINK2: 20-pi (0.1 & 2mm) - used o most evaluatio boards. 10-pi (0.05 ) - ew space savig coector. JTAG, W ad WV iterfaces are all supported withi the stadard 20-pi ad 10-pi coector pi-outs. Further iformatio is available at ETM Trace ome ARM Powered devices also iclude a Embedded Trace Macrocell (ETM) which eables istructio ad data trace. MDK supports this style of trace with the additio of a third-party trace uit ad a software plug-i. ULINK2 UB-JTAG Adapter 10-pi (0.05 ) 20-pi (0.10 & 2mm) ULINK2 supports three ARM debug coectors 4

5 RTX RTO Kerel RTX Kerel Today, microcotroller applicatios demad more critical cotrol, ofte requirig simultaeous executio of multiple tasks i a real-time eviromet. While it is possible to implemet a embedded program without usig a real-time kerel, the prove Keil RTX allows developers to cocetrate o applicatio developmet, save time, produce a reliable, expadable system ad makes software developmet easier. RTX is a royalty-free, determiistic real-time kerel with multiple task priority levels, roud-robi, ad preemptive cotext switchig. It has bee specifically developed for the ARM architecture, with a further optimized Cortex-M feature-set.

RTX supports up to 254 active tasks, each with 254 priority levels, multiple istaces of the same task are supported. Task tacks are allocated from a stack memory pool or ca be supplied whe a task is created. Fast Memory Pool Maagemet allows you to create a ulimited umber of fixed size pools while providig fully determiistic allocatio times. Evet Flag Maagemet allows sychroizatio with up to 16 evet flags per task. Time Maagemet ad Timer Callback Fuctios support time delays (iterval or timeout) for tasks. Kerel Aware Debuggig RTX is fully itegrated i the µvisio Debugger makig it easy to moitor task status ad kerel activity. The RTX dialogs display all aspects of the kerel; such as active tasks, stack loadig, ad system resource usage. CODE ad RAM space deped o which RTX fuctios are used. Detailed performace figures are available at RTX is provided as fully cofigurable object code withi the Microcotroller Developmet Kit ad as source code i the Real-Time Library. Task ad evet timig is coveietly displayed i the Evet Viewer, more detailed iformatio ca be viewed by poitig the cursor at specific poits. 5 RealView Microcotroller Developmet Kit
