2. Quick Start Training Advanced CoolRunner-II Techniques-II On the Fly Reconfiguration (OTF) – Understanding OTF – OTF Applications DataGATE – Understanding DataGATE – DataGATE Applications

3. Quick Start Training On the Fly Reconfiguration (OTF) OTF exploits the RealDigital cell architecture Initial pattern is loaded into a configuration shifter The pattern first transfers into nonvolatile memory The pattern is then read from NV to SRAM for actual cell operation Leaves ability to reload the NV memory as we say, “On the Fly”

4. Quick Start Training CoolRunner-II High Level Architecture

5. Quick Start Training Behind the Scenes Configuration Memory

6. Quick Start Training Reconfiguration Process Nonvolatile Cell Volatile Cell

7. Quick Start Training Reconfiguration Process Blank Initial Condition

8. Quick Start Training Reconfiguration Process Pattern 1 Blank Nonvolatile Programmed with Pattern 1

9. Quick Start Training Reconfiguration Process Pattern 1 Both programmed with Pattern 1

10. Quick Start Training Reconfiguration Process Pattern 2Pattern 1 Pattern 1 in Volatile Pattern 2 in Nonvolatile

11. Quick Start Training Reconfiguration Process Pattern 2 Pattern 2 in Both

12. Quick Start Training WebPACK ISE5.2i Supports iMPACT utility that permits OTF updates User loads first pattern, then “inits” the part Second pattern load occurs while first one runs Init can be issued at any time the user wishes After 50-100 microseconds, new pattern is running Its that easy!

15. Quick Start Training OTF Applications Uploading FPGA and changing function Building small tables in Function Blocks Changing PicoBlaze instructions Changing keys on stream ciphers Board level testing

16. Quick Start Training Configure FPGA then Handle Interrupts At power up CPLD configures FPGA (SelectMap JEDEC) FPGA active,CPU configures CPLD w. Interrupt JEDEC CPLD active, CPU configures CPLD w. SelectMap JEDEC System can be power cycled as needed FPGA Bitstream CR-II FPGA CPU Interrupt JEDEC SelectMap JEDEC 3 JTAG Select Map

17. Quick Start Training Small Tables CoolRunner-II CPLD has multiple Function Blocks Each Function Block has Programmable Logic Array (PLA) PLA can also create “miniEPROM” or a table Can reprogram OTF Tables can hold constants, perform arithmetic, etc. FB AIM

18. Quick Start Training Reloading an Instruction Set See PicoBlaze demonstration to see this in action!

19. Quick Start Training Re-Keying a Stream Cipher Encryption can be done with Linear Feedback Shift Registers (LFSR) Seed values and tap points can be changed OTF EX-OR Clear Bits to Encrypt Changing “key” can be done while the part operates Fancy LFSRs exist for better results (see Security presentation for detail) D Q LFSR Clear Bits Encrypted Bits

20. Quick Start Training Board Testing Test patterns from CPLD drive/respond to other chips on board CPLD is updated via JTAG from off/on board CPU CPLD assumes different function when not testing board PCB
