Splitting quotient and remainder could be something indeed.
Others have mentioned that, however I'll post the following trivial
modification of one of your early sources:
$ cat tempo2.c
#include <stdio.h>
#include <stdint.h>
#include <stdlib.h>
int main(int argc, char **argv)
{
if (argc != 4) {
printf("usage: %s ticks tempo grouplen\n", argv[0]);
} else {
uint32_t r1, r2, r3, r4, r5, r6;
uint32_t ticks = atoi(argv[1]);
uint32_t tempo = atoi(argv[2]);
uint32_t grouplen = atoi(argv[3]);
r1 = ticks * tempo / grouplen;
r2 = ticks * (tempo / grouplen);
r3 = (ticks * (((tempo << 3) / grouplen))) >> 3;
r4 = (uint64_t)ticks * (uint64_t)tempo / grouplen;
{
uint32_t quot1 = tempo/grouplen;
uint32_t rem1 = tempo % grouplen;
r5 = ticks*quot1 + (rem1 * ticks)/grouplen;
uint32_t quot2 = ticks/grouplen;
uint32_t rem2 = ticks % grouplen;
r6 = ticks*quot1 + rem1*quot2 + (rem1 * rem2)/grouplen;
}
printf("r1 = %u\nr2 = %u\nr3 = %u\nr4 = %u\nr5 = %u\nr6 = %u\n",
r1, r2, r3, r4, r5, r6);
}
return 0;
}
$ cc -std=c11 -Wall tempo2.c && ./a.out 9120 1090909 15370
r1 = 88429
r2 = 638400
r3 = 646380
r4 = 647305
r5 = 647305
r6 = 647305
Assuming that the final result fits in 32 bits, r5 is exact as long as:
grouplen*ticks < UINT32_MAX
r6 is exact as long as:
grouplen*grouplen < UINT32_MAX
The r5 expression could also be refactored so as to require
grouplen*tempo < UINT32_MAX, but your example is already out of this range.
The expressions are also simple enough to be coded directly in x86 asm,
for example you may know that the 'div' instruction yields quotient and
remainder in one go - however, many decent optimizing compilers may do
the same and more.
