3 µvisio2 IDE Project Maagemet A project is composed of all the source files, developmet tool optios, ad directios ecessary to create a program. A sigle µvisio2 project ca geerate oe or more Target programs, each with its ow set of optios. The source files used to create a target are orgaized ito Groups. Optios may be set at the target, group, or file level. Tool setup is simplified with itelliget optios dialog pages. For example, the liker cofiguratio is derived from the off-chip memory address specificatios ad the o-chip memory sizes from the Device Database. Source Code Editor The µvisio2 editor icludes all the editig features to which you are accustomed. Color sytax highlightig ad text idetatio are optimized for C ad assembler source code. Editig is eve available while debuggig so you ca quickly test ad make chages to your applicatio. Itegrated Utilities µvisio2 cotais powerful features that help you complete your projects o time: The itegrated Source Browser maitais a database of your program s symbols for quick avigatio through your source files. You may use the detailed iformatio to optimize the memory types of variables. Fid i Files performs a global text search i all specified files. The Tools Meu allows you to start thirdparty utilities from withi the µvisio2 IDE. A cofigurable SVCS iterface provides access to Versio Cotrol Systems. The PC-Lit iterface gives you advaced sytax aalysis of your applicatio code. The Flash tool iterface itegrates third party flash dowload utilities.

4 C51, CX51, ad C251 Compiler The Keil 8051 ad 251 developmet kits cotai differet C compilers for optimum support of the various device variats. Cx51 is used as geeric term for these compilers: C51 Compiler for classic 8051 devices CX51 Compiler for Philips MX extesios C251 Compiler for the 251 architecture New Code Optimizatios Cx51 Versio 7 adds ew optimizatios that geerate smaller programs ad help you put more features i less code space (so you ca fit larger programs i sigle-chip devices). Dyamic Register Allocatio puts more variables i registers ad reduces code (fewer MOV istructios are geerated) ad data space (less overlaid data is required). Commo Tail Optimizatio combies idetical code i coditioal statemet blocks ad further reduces code space. Memory ad SFRs The Cx51 compiler provides complete access to all hardware compoets. Access to special fuctio registers is provided by the sfr ad sbit keywords. Variables may be assiged to ay address space. The _at_ keyword allows you to locate variables at fixed memory addresses. The Liker supports code bakig ad the µvisio2 Debugger supports up to 16MB of code ad xdata space for program testig. Flexible Poiters Cx51 provides two kids of poiters. Geeric poiters store the memory type ad the address of a object i three bytes ad may access ay variable regardless of its locatio i the 8051 memory space. Memory-specific poiters are declared with a memory type ad refer to a specific memory area. Addresses are 1-2 bytes so poiter accesses are fast.
