[Keep It Simple,Stupid] Board.
The board was evaluated like [or1k/orp project].

BOARD consists of two pieces. One is FPGA board. Another is MOTHER board. 
The device on the FPGA board is ANY(xilinx or altera ...).
Only connected specification of the board is important.
  

• It's planning(more cheap!)

• It's finished(commit code,RTL8019AS Evaluation is done)

• MISC condition

  - VramRenderRoutine on EXT_FLASH[.text section](include Cache)
  - InterruptsHandler on QMEM[.icm section]
  - ImageDataSize(40x50pixel) is 4000byte(include Cache)
  - The byte_order of QMEM is enable.

- Reduce cost
  - This is Expensive or Cheap?
  - How to do?(thinking)
- The examination point is put out. 
  - How is the Debug-Interface-pin?
- This WEB page is maintained
  - Add Board electrical information
  - Add Teaching material information
