  3. What is Processor Expert? A rapid application design tool with … • Graphical User Interface which allows an application to be specified by the functionality needed • Automatic code generator which creates tested, optimized C code tuned to the application needs and selected Freescale MCU • Built-in knowledgebase, which immediately flags resource conflicts and incorrect settings Creating… • Hardware Abstraction Layer (HAL) – hardware-dependent, low-level drivers with a known application programming interface (API) Benefits • Eases migration between Freescale devices • Designers don’t have to be intimately familiar with every page of a specification • Errors are caught early in design cycle; therefore, designers get to market faster with higher quality product

  4. Unique in the Market • Processor Expert delivers functionality that is unique in the market. * Software support for ARM competitors

  5. Processor Expert Tools Several approaches • Low level • Use ASM/C (Assembler Support Routines) • Code is specialized • Classical approach • Use primarily C • Reuse of existing code • Use SDK (Software Development Kit) and libraries • Components • Abstraction • Formal description of the algorithm • Modeling (State charts) Device Initialization Processor Expert State Builder

  8. Terminology and Windows

  9. Processor Expert Terminology What is an Embedded Bean? • Embedded Beans encapsulate the initialization and functionality of an embedded system’s basic elements, such as CPU core, CPU on-chip peripherals, FPGAs, stand-alone peripherals, virtual devices and pure software algorithms. • Embedded Beans provide a hardware abstraction layer (HAL), which eases migration between devices. What is a template? • Templates are Embedded Beans, which have already been either partially or completely configured • Templates can be used to share pre-defined settings with a team of designers

  10. Processor Expert™ Windows Processor Expert is integrated into the HC(S)08/RS08, HCS12(X) and DSC CodeWarrior tool suites. It adds the following windows to those tool suites: • Processor Expert Panel in Project Manager • Target CPU • Bean Selector • Bean Inspector

  11. Processor Expert™ Windows • Target CPU Window: • Displays selected target microcontroller with its peripherals and pins • Displays current resource usage by selected beans (i.e. peripherals, pins) • Data directions of single pins are indicated by blue arrows when configured by a bean • Pins associated with a peripheral are highlighted when mouse hovers over a peripheral • Help is available for pins and peripherals by moving the mouse over the item • Several display modes are supported. To change mode - push a button in the left side menu.

  12. Processor Expert™ Windows • Bean Selector Window: • Shows supported Embedded Beans including CPU beans and bean templates. • Allows an Embedded Bean or template to be added to the project. • Embedded Beans can be listed by categories, alphabetically or on-chip peripherals. • Right-click on a bean to add it to the project or to get help. • An assistant is also available to guide bean selection

  13. Processor Expert™ Windows • Bean Inspector Window – Properties Tab: • Double-clicking on an Embedded Bean opens the Bean Inspector window • A red exclamation point means one of the bean’s properties is either blank or in conflict with another. • Help is available for the fields by moving the mouse over them. • The Basic, Advanced and Expert buttons at the bottom of the window control the level of detail visible.

  14. Processor Expert™ Windows • Bean Inspector Window – Methods Tab: • Shows functions available for the Embedded Bean • Allows designer to select functions to be included in his application • Code is only generated for • selectedfunctions • The code will appear in the .c file • for this Embedded Bean in the “Generated Code” folder • Holding the mouse over a • “method” causes a description • of the function’s parameters and return values to be displayed

  15. Processor Expert™ Windows • Bean Inspector Window – Events Tab: • Shows the events for the current Embedded Bean • Allows events to be renamed • Events are usually called by interrupts • Events are defined in Events.c in the “User Modules” folder
