原创 PSP相关文件的结构

PSP顶层是一个xml文件，主要描述该Platform主要的components：

主要components都有自己的xml描述：

文件存储结构，recommended
by Impulse C:

Example:
gidel_procwizard_ps3.xml  //top level
Platform definition

<?xml
version='1.0'?>

<!DOCTYPE
architecture PUBLIC "" "">

<architecture
version="1.0" name="GiDEL PROCWizard (PROCStar III)">

<bus name="procwiz0"
file="VHDL/GiDEL/PROCWizard_PS/bus_PS3.xml"/>

<pe name="pe0" target="VHDL/target.xml"
technology="VHDL/Altera/technology.xml"
system="VHDL/Generic/Generic/system.xml" cpu="cpu0"
bus="procwiz0"/>

<proc
name="cpu0" file="GiDEL/cpu.xml"
bus="procwiz0"/>

<mem name="mem0" bus="procwiz0"
alloc="malloc"/>

<exporter
file="GiDEL/GiDEL_export.tcl"/>

<library name="float"
file="VHDL/Altera/float.xml"/>

</architecture>

负责生成bus wrapper的bus_PS3.xml文件定义了所需hardware
library和Tcl script：

<?xml
version='1.0'?>

<!DOCTYPE
bus PUBLIC "" "">

<bus
name="procwizard" version="1.0">

<param name="width"
value="*"/>

//生成bus wrapper HDL所需的Tcl脚本

<busgen
file="VHDL/GiDEL/PROCWizard_PS/genbus_PS3.tcl"/>

//所需库文件

<require file="VHDL/GiDEL/PROCWizard_PS/lib/wr_mem_intfc.vhd"
dst="lib" type="hdl"/>

<require
file="VHDL/GiDEL/PROCWizard_PS/lib/rd_mem_intfc.vhd"
dst="lib" type="hdl"/>

<require
file="VHDL/GiDEL/PROCWizard_PS/lib/inp_stream_intfc.vhd"
dst="lib" type="hdl"/>

<require file="VHDL/GiDEL/PROCWizard_PS/lib/out_stream_intfc.vhd"
dst="lib" type="hdl"/>
