本文简单讨论并总结了VHDL、Verilog，System verilog 这三中语言的各自特点和区别As the number of enhancements to variousHardware Description Languages (HDLs) hasincreased over the past year, so too has the complexityof determining which language is best fora particular design. Many designers and organizationsare contemplating whether they shouldswitch from one HDL to another.

This application note shows how to write an Inter Integrated Circuit bus driver (I²C) for the Philips P90CL301micro-controller.It is not only an example of writing a driver, but it also includes a set of application interface software routines toquickly implement a complete I²C multi-master system application.For specific applications the user will have to make minimal changes in the driver program. Using the drivermeans linking modules to your application software and including a header-file into the application sourceprograms. A small example program of how to use the driver is listed.The driver supports i.a. polled or interrupt driven message handling, slave message transfers and multi-mastersystem applications. Furthermore, it is made suitable for use in conjunction with real time operating systems, likepSOS+.

This application note describes a reference system which illustrates how to build an embeddedPowerPC® system using the Xilinx 1-Gigabit Ethernet Media Access Controller processor core.This system has the PLB_Gemac configured to use Scatter/Gather Direct Memory Access andthe Serializer/Deserializer (SerDes) interface. This application note describes how to set up thespecific clocking structure required for the SerDes interface and the constraints to be added tothe UCF file. This reference system is complete with a standalone software application to testsome of the main features of this core, including access to registers, DMA capabilities, transmitand receive in loopback mode. This reference system is targeted for the ML300 evaluationboard.
