XAPP520將符合2.5V和3.3V I/O標(biāo)準(zhǔn)的7系列FPGA高性能I/O Bank進行連接
The I/Os in Xilinx® 7 series FPGAs are classified as either high range (HR) or high performance (hp) banks. HR I/O banks can be operated from 1.2V to 3.3V, whereas hp I/O banks are optimized for operation between 1.2V and 1.8V. In circumstances that require an hp 1.8V I/O bank to interface with 2.5V or 3.3V logic, a range of options can be deployed. This application note describes methodologies for interfacing 7 series hp I/O banks with 2.5V and 3.3V systems

oRTP is a LGPL licensed C library implementing the RTP protocol (rfc1889). It is available
for most unix clones (primilarly Linux and hp-UX), and Microsoft Windows.
The libosip library is known to compile on various platform:
* GNU/Linux
* MacOSX (Darwin)
* OpenBsd 3.1/3.2 // (FreeBSD&NetBSD should also work)
* Windows NT/95/2000 (VC++6.0 or cygwin)
* Solaris
* hp-Unix.
* VxWorks.
* Some embedded systems with linux.
* WinCE (report to be possible)
