You're a bit short on detail, but remember to use the tiny memory model for the 2051.
Run the code on a simulator, set for the memory sizes in the 2051. One thing to watch, is the 2051 has 128 bytes SRAM. For new designs, you might want to look at the AT89LP series, and the AT89LP2052 has 256 bytes of SRAM, and is generally faster/smarter.
