Xilinx upgrade

Have you taken a look at Xilinx' website? There is a wealth of infomation there...but....

EDK =3D Used to develop FPGA systems that use either a MicroBlaze soft processor or a PowerPC hard processor. ISE =3D Used to develop FPGA or CPLD systems that may or may not contain a processor (probably don't - that is why the EDK is nice). IP =3D Intellectual Property...or specifically related to what you are asking...predesigned hardware blocks that do some prescribed function.

ISE - tools for building fpga hardware EDK - tools for building uP software and managing IP blocks IP = intellectual property - uarts, bus controllers, etc.
