## Planned Modules
|
|
|
|
- SD Card Reader
|
|
|
|
- VGA Controller
|
|
- Not sure if the framebuffer is here or in RAM?
|
|
- Each pixel is 12-bits
|
|
- Probably fit into 16-bit words in RAM?
|
|
- Plan on 640x480
|
|
- Should we do double buffering?
|
|
|
|
- Audio Controller
|
|
- Again, not sure how the buffer will work. Might just take in 1KiB as a
|
|
verilog array?
|
|
|
|
- Control logic
|
|
- Play
|
|
- Pause
|
|
- Volume up/down
|
|
- Fast forward
|
|
- Maybe start at 2x, then go to 4x then 8x with more presses?
|
|
- Rewind, maybe, it's real hard though
|
|
|
|
- DRAM/SRAM controller
|
|
- We might need this for buffering frames? Not sure if we implicitly can use
|
|
SRAM with verilog arrays
|
|
- The SRAM interface is easier but slower
|
|
- Hopefully we don't need this but who knows
|
|
|
|
- 8 segment display driver
|
|
- Takes in a play time in seconds and displays it in hour:minute:second
|
|
- Maybe could take in seconds, minutes, and hours separately?
|
|
- This would save us from having to do modulo
|
|
- It'd be easy to check if seconds == 60 and then increment minutes
