If you examine your Nios II Embedded Evaluation Kit, Cyclone III
Edition, you will find that it is comprised of 2 boards, the Cyclone III
FPGA Starter Board and the LCD Multimedia Daughtercard. On the
Cyclone III FPGA Starter board resides the Cyclone III 3c25 FPGA which
configures from flash with the Nios II Standard Processor System on
startup.

between the two boards. This detail was removed for simplicity.
On the LCD Multimedia Daughtercard resides a MAX II CPLD whose
function is to relay data and control signals to the various peripheral
devices as shown in the
translation and de-multiplexing of video pipeline signals to the LCD
Development Board Version 1.0.
