HP AMP
USB-FPGA
It corresponds to USB2.0. output for LVDS.
In the FPGA, the firmware is writted by
the process that is from
the Computer, the miniUSB terminal and
ending of the system・the microcomputer
(ARM Cortex-M3)
(Don't need the personal reader).
It's loaded with a XC6LX4TQG144
( Spartan-6.Xilinx), USB2.0 microcomputer
of CY7C68013A(Cypress), and S/PDIF
audio・interface of AK4118(Asahi Kasei).
