Is there any way to dynamically allocate memory on an 8051?


Yes. The source code for the memory allocation routines are found in the KEILC51LIB folder. You must set up the memory allocation routines to use XDATA for the memory pool. Check the following source files:

INIT_MEM.C (Initializes the memory pool)
CALLOC.C (Calloc routine)
FREE.C (Free routine)
MALLOC.C (Malloc routine)
REALLOC.C (Realloc routine)
