  1. Lab 9 ASIC Logic 第八組 R91943003 陳方玉 R91943007 陳建宏 R91943072 柯鴻洋 R89921022 吳佑焉

  2. Outline • Introduction to the ASIC Logic • Experiment Steps • RGB to YUV Conversion HW Module

  3. Outline • Introduction to the ASIC Logic • Experiment Steps • RGB to YUV Conversion HW Module

  4. Basics for Prototyping with Logic Modules

  5. Basic Platforms: AHB

  6. Logic Module Registers

  7. Outline • Introduction to the ASIC Logic • Experiment Steps • RGB to YUV Conversion HW Module

  8. Steps for Example 1 (1)Flash the LEDs on the Logic Module from left to right. (2)The speed of flashing the LEDs from left to right can be set by changing the configuration of the 8-way switch. (3) Comparison of programming FPGA FPGA version: programs the FPGA by writing the bit stream image into the FPGA directly. The image will start running right after programming into the FPGA. Flash version: programs the FPGA by writing the bit stream image into the flash. The image will start after next power up of the development system.

  9. Steps of Example 1 Control Clock Frequency by 8-Way Switches Setting Clock Frequency

  10. Steps of Example 2 (1)Determine the DRAM size on the Core Module and set up the system controller (2)Make sure the Logic Module is present in the AP expansion position (3)Report module information (4)Set the Logic Module clock frequencies (5)Test SSRAM for word, halfword, and byte accesses (6)Test the custom design device’s single register access Flash the LED (7)Remain in a loop that displays the 8-way switch value of the Logic Modules on its LEDs. These steps are the same as in experiment 8: AMBA BUS

  11. Reminder

  12. Reminder Remember to set the third switch on Program FPGA from Image 0

  13. Experiment Steps:example2

  14. Outline • Introduction to the ASIC Logic • Experiment Steps • RGB to YUV Conversion HW Module

  15. RGB to YUV Conversion • Implement with pure software. • Implement with hardware.

  16. Memory Definition LM_MYIP=0xC2200040

  17. RGB to YUV Program (1)Add MYIP.v into top module. (2)Modify AHBDecoder.v. (3)Modify AHBMuxS2M.v. (4)Modify AHBAHBTop.v.

  18. Architecture

  19. Modification of AHBAHBTOP.v

  20. RGB to YUV Program Modification of AHBDecoder.v

  21. RGB to YUV Program Modification of AHBMuxS2M.v

  22. MYIP.v modified from AHBZBTRAM.v

  23. MYIP.v modified from AHBZBTRAM.v Divide HWDATA into r,g,b parts Combine y,u,v into output HRDATA (2:1:1)

  24. Initialize LM Module Software Implementation Write RGB value into LM_MYIP and read YUV as data_myip Post processor for data_myip to read out YUV value Logic.c

  25. Logic.h Set Registor for LM_MYIP

  26. Input parameters Result of Pure Software Implementation Result of Hardware Implementation

  27. Verilog Coding • Confusion btw. Signed and Unsigned Multiplication • Truncation • 負數的二進位轉換 • 小數點對齊

  28. Reference • Integrator ASIC Platform [DUI_0098B_AP_UG] • System Memory Map [DUI_0098B_AP_UG 4.1]
