Fast 32-bit binary to compact BCD conversion - Keil Shell 2.0
The function fast_binary_to_bcd() converts a 32-bit (long
unsigned int) to 10 digits of compact Binary Coded Decimal
(BCD). The eight least significant BCD digits are returned in
R4-R7 so as to be compatible with Keil function return value
standards for an unsigned long int. The two most significant
decimal digits are returned in R3. fast_binary_to_bcd() uses
the currently selected register bank, the Data Pointer (DPH
only) and general purpose registers. No memory or stack is
required. The function is written in a Keil shell and may
easily be incorporated into a Keil C51 based project. However,
all the functionality is expressed in assembler and the
function may easily be converted to work with any assembly
language environment. A test harness is provided.
