If you want a vhdl 8052 the first question is why?
The second thing is as i said to someone else from here VHDL is not a plug and play solution and if you have no experiance with vhdl or fpga's then you will not be succesfull in implementing such a large and complex design, given the vhdl code.Implementing a vhdl design is not just about pointing some vhdl at a device and expecting it to work.
The third point is the the only viable options with regard to fpga's today interms of the software support and the physical devices able to support such a device are altex and xilinx.
Having said all that and you are still after a 8052 compatable core running 4 cycles per instruction and all the hand holding you require in order to implement it which is not available elsewhere all at low low prices then don't delay contact me today:-)
