This is a well written ip 51 core and VHDL sources free of charge
10 times fatester than the intel original architecture

this is another one but .. not free!

What a treat this CORE IS! .It comes with a MULTISIM testbench and also it compiles without errors using simplify pro7.31

A very useful core to implement PSOC designs.. Use it. is free and ready to go!!!!!!!!!!!!!!!!!!!!!!!!
 

do u have any idea about how to write the core ?
give a detail document
 

what is the difference between those ?
 

Yes quite an interesting one, 8.4 times faster than the original.. But quite hungry on gates! So quite expensive to implement in a FPGA. For the same price, can get a much powerful processor of the shelve. By the way it does compile as well with leonardo spectrum and therefore can be implemented in almost all FPGA vendors.. So for the 8051 'fans' go for it..
:D
