Host data pump ? Idle CPU load ? Your function Program ? Insert functions to execute within idle ? Lowest priority SWI thread ? Set up with Config Tool ? Continuous loop round robin ? Realtime analysis plugins updated C main () 36 RealTime Analysis Determine whether the system is: Operating within its design specifications Meeting its performance targets Showing any subtle timing problems Analyze realtime operation: Software logic analyzer CPU load Thread timing and count statistics 37 How do I ?BIOSize? my Code? 1. Start a new project 2. Set up objects with Configuration Tool 3. Migrate interrupt vector table to the HWI module 4. Migrate memory sections from file to MEM module 5. Save and Add the .cdb file to your project 6. Edit C source for include headers and declare variables 7. Change C functions within your program 8. to DSP/BIOS APIs. 9. Build the new project Also… try the CC Studio Tutorial examples …and study the DSP/BIOS by Degrees app note SPRA591 … also Audio Example DSP/BIOS app note SPRA598 Starting New Projects C New Project () Add source files Add linker mand file Add RunTime library BIOS New Project () Setup new configuration Add configuration file () Add source files Add linker mand file Set Up System Easily with Configuration tool Easy to visually configure runtime objects ? Set global runtime parameters ? Statically configures objects ? Detect errors early by validating ? properties before execution ? Calculate estimated data and minimal ? stack size ? Minimize target memory footprint by ? eliminating runtime code Saves time by getting you started quickly ? Adds basic Run Time services ? Add interrupt vector definitions ? Add memory section definitions ? Optionally add thread scheduling ? Optionally add low overhead instrumentation objects ? Visually create runtime objects bound to the executable program 40 Summary DSP/BIOS Modules ATM Atomic Functions CLK Clock Manager DEV Device Driver Interface GBL Global Properties HST Host Channel Manager HWI HW Interrupt Manager IDL Idle Manager LCK Resource Lock Manager LOG Log Event Manager MBX Mailbox Manager MEM Memory Manager PIP Pipe Manager PRD Periodic Function Manager QUE Queue Function Manager RTDX Real Time Data Exchange SEM Semaphores SIO Stream I/O STS Statistics Accumulator SWI SW Interrupt Manager SYS System Services TRC Trace State TSK MultiTasking Where do these fit?
