Can FPGA replace those architecture based on FPGA+DSP

[zhj1985]

Generally, the most popular DSP archetecture which focused on complex digital signal processing is based on DSP +FPGA. FPGA is often used as a coprocessor for a DSP because those PowerPC 440 cores aren't as fast as DSP and those algorithms which are developed by C language can be developped more easily than those developed by Verilog or VHDL language.

However, as the time goes, FPGA has developped fast in recent years. I want to ask that whether those complex digital system which was based on DPS+FPGA can be replaced by FPGA now. And if it is, then how can I do that? I know Xilinx has developed those software such as system generator, but I don't know whether it can work out.

i think it will be FPGA+ARM's future!
because DSP has been embedded in it!

The new VIRTEX 4 and 5 Have a powerpc 440 core with a vector unit .This units are very sofisticated and code can be parellelized with a special program called a VECTORIZER it ouperforms a Ti C6711 !
