TigerSHARC Laboratory Setting up the HPP-ICE environment ICT 318 / 320 Running versions of the Audio-talk-through program

16 December 2006Setting up TigerSHARC laboratory station2 Details In Winter Blackfin ADI-BF533 Ez-lite evaluation boards in ICT TigerSHARC ADI-TS201S Ez-lite evaluation boards in ICT 318 Blackfin interface TigerSHARC interface is similar Has 2 audio I/O sockets (DSP A) plus 2 LEDs and 3 buttons (DSP A) plus 2 LEDs and 3 buttons (DSP B)

16 December 2006Setting up TigerSHARC laboratory station3 Set up If you use the same lab. station and same account each time (recommended), then you will have to do the set up just once. If you move stations, then you will need to do the set-up everytime

16 December 2006Setting up TigerSHARC laboratory station4 Steps Power-up evaluation board Log into your account Set-up on your U: drive the directory ENCM515 Activate the VisualDSP configurator and “make a dual processor ENCM515 session”. Then exit from configurator. Activate the Visual DSP development environment IDDE, select “dualENCM515” session, build (or download) a VisualDSP TigerSHARC project, or download an existing one. You are on your way

16 December 2006Setting up TigerSHARC laboratory station5 Activate the configurator from the start menu

16 December 2006Setting up TigerSHARC laboratory station6 Select TS201 EZ-Lite and then press “COPY”

16 December 2006Setting up TigerSHARC laboratory station7 Change PLATFORM NAME to dualProcessorENCM515 then OK

16 December 2006Setting up TigerSHARC laboratory station8 When back at CONFIGURATOR Select “dualProcessorENCM515” Then select Test

16 December 2006Setting up TigerSHARC laboratory station9 Change TYPE to HPPCI-ICE Press START Recommend you do this test at the beginning of each lab

16 December 2006Setting up TigerSHARC laboratory station10 This was a “failure to power up board”, can also be “no ICE connected” (e.g. wrong TYPE)

16 December 2006Setting up TigerSHARC laboratory station11 Expected result If you see “1 JTAG device detected”, you are at a Blackfin station – Change rooms

16 December 2006Setting up TigerSHARC laboratory station12 Testing complete Select OK

16 December 2006Setting up TigerSHARC laboratory station13 Now ready to activate VisualDSP IDDE

16 December 2006Setting up TigerSHARC laboratory station14 TARGET: You must select the correct “session” for TS201S

16 December 2006Setting up TigerSHARC laboratory station15 I)Select Processor Family 2) Select TS201, then NEXT

16 December 2006Setting up TigerSHARC laboratory station16 3) In LAB. select Emulator elsewhere select EZ-KIT (uses USB)

16 December 2006Setting up TigerSHARC laboratory station17 4) Select dualProcessorENCM515 for the platform

16 December 2006Setting up TigerSHARC laboratory station18 WHICH DSPS ARE RUNNING PROJECT WINDOW COMMAND and BUILD WINDOWS DISASSEMBLY WINDOW

16 December 2006Setting up TigerSHARC laboratory station19 Download Environment Exit from VisualDSP IDDE Change directory to U:ENCM515Labs Directory Download ENCM515Environment.zip into U:ENCM515Labs Extract to here MAKE SURE THE UNZIP WENT CORRECTLY. IF THINGS WENT INTO WRONG FOLDER THEN MORE WORK TO BE DONE IN LABS AND ASSIGNMENT

16 December 2006Setting up TigerSHARC laboratory station20 Make sure you are not in a subdirectory You may find a DSPUtilities directory U:/ENCM515Labs/

16 December 2006Setting up TigerSHARC laboratory station21 Open the existing ENCM515Lab1 project in U:/ENCM515Labs/Lab1

16 December 2006Setting up TigerSHARC laboratory station22 Look in ENCM515Lab1Def.h

16 December 2006Setting up TigerSHARC laboratory station23 Audio Talkthrough Program Connect up your ear-phones to I-POD, radio, CD player (can use the CD player in Lab. Station) Check that volume is comfortable to listen to Connect IPOD to TigerSHARC audio in Connect Earphones to TigerSHARC audio out

16 December 2006Setting up TigerSHARC laboratory station24 Do a BUILD and then DEBUG | RUN

16 December 2006Setting up TigerSHARC laboratory station25 Warning: Make sure that Processor DSP A is running – otherwise no sound You may need to click on DSP A before selecting DEBUG | RUN

16 December 2006Setting up TigerSHARC laboratory station26 DSP-A is running Set View | Editor Tab

16 December 2006Setting up TigerSHARC laboratory station27 Now see file names

16 December 2006Setting up TigerSHARC laboratory station28 Listen to various forms of the program Quality of sound Time how long delayed sound takes to arrive at the other ear Do this with each mode of operation #define WHICH_AUDIOHANDLER audio_intShuffle_DebugMode //#define WHICH_AUDIOHANDLER audio_intShuffle_ReleaseMode //#define WHICH_AUDIOHANDLER audio_intCB_DebugMode //#define WHICH_AUDIOHANDLER audio_intCB_ReleaseMode

16 December 2006Setting up TigerSHARC laboratory station29 Delay by memory shuffle and circular buffer

16 December 2006Setting up TigerSHARC laboratory station30 Look at what code is executing CommonShuffle_CPPCode.h Delay line performed by shuffling (move) DelayLine[N]  DelayLine[N-1]; CommonCB_CPPCode.h Circular Buffer operation Debug mode C++ compiler generating unoptimized code Release mode (files marked with ! ) C++ compiler generating optimized code

16 December 2006Setting up TigerSHARC laboratory station31 TimeToWaste Parameter When running circular buffer code, adjust the parameter “TIME_TO_WASTE” to see how much extra time is available for extra processing. Try increasing in steps of 0x1000 until sound quality gets worse. Later we will turn this number into processor cycles.

16 December 2006Setting up TigerSHARC laboratory station32 Testing by listening is very time consuming We need an automated test framework to make code optimization easier Will discuss in the next class
