Note that z will be - chosen so that division by z is cheap. - - Let r be the remainder(z/y). In other words, r = z - ay. - - Now, our method is to choose a value for b such that - - q'(x) = floor((ax+b)/z) - - is equal to q(x) over as large a range of x as possible. If the - two are equal over a sufficiently large range, and if it is easy to - form the product (ax), and it is easy to divide by z, then we can - perform the division much faster than the general division algorithm. - - So, we want the following to be true: - - . For x in the following range: - . - . ky <= x < (k+1)y - . - . implies that - . - . k <= (ax+b)/z < (k+1) - - We want to determine b such that this is true for all k in the - range {0..K} for some maximum K. - - Since (ax+b) is an increasing function of x, we can take each - bound separately to determine the "best" value for b. - - (ax+b)/z < (k+1) implies - - (a((k+1)y-1)+b < (k+1)z implies - - b < a + (k+1)(z-ay) implies - - b < a + (k+1)r - - This needs to be true for all k in the range {0..K}. In - particular, it is true for k = 0 and this leads to a maximum - acceptable value for b. - - b < a+r or b <= a+r-1 - - Taking the other bound, we have - - k <= (ax+b)/z implies - - k <= (aky+b)/z implies - - k(z-ay) <= b implies - - kr <= b - - Clearly, the largest range for k will be achieved by maximizing b, - when r is not zero. When r is zero, then the simplest choice for b - is 0. When r is not 0, set - - . b = a+r-1 - - Now, by construction, q'(x) = floor((ax+b)/z) = q(x) = floor(x/y) - for all x in the range: - - . 0 <= x < (K+1)y - - We need to determine what K is. Of our two bounds, - - . b < a+(k+1)r is satisfied for all k >= 0, by construction. - - The other bound is - - . kr <= b - - This is always true if r = 0. If r is not 0 (the usual case), then - K = floor((a+r-1)/r), is the maximum value for k. - - Therefore, the formula q'(x) = floor((ax+b)/z) yields the correct - answer for q(x) = floor(x/y) when x is in the range - - (0,(K+1)y-1) K = floor((a+r-1)/r) - - To be most useful, we want (K+1)y-1 = (max x) >= 2**32-1 so that - the formula for q'(x) yields the correct value of q(x) for all x - representable by a single word in HPPA. - - We are also constrained in that computing the product (ax), adding - b, and dividing by z must all be done quickly, otherwise we will be - better off going through the general algorithm using the DS - instruction, which uses approximately 70 cycles. - - For each y, there is a choice of z which satisfies the constraints - for (K+1)y >= 2**32. We may not, however, be able to satisfy the - timing constraints for arbitrary y. It seems that z being equal to - a power of 2 or a power of 2 minus 1 is as good as we can do, since - it minimizes the time to do division by z. We want the choice of z - to also result in a value for (a) that minimizes the computation of - the product (ax). This is best achieved if (a) has a regular bit - pattern (so the multiplication can be done with shifts and adds). - The value of (a) also needs to be less than 2**32 so the product is - always guaranteed to fit in 2 words. - - In actual practice, the following should be done: - - 1) For negative x, you should take the absolute value and remember - . the fact so that the result can be negated. This obviously does - . not apply in the unsigned case. - 2) For even y, you should factor out the power of 2 that divides y - . and divide x by it. You can then proceed by dividing by the - . odd factor of y. - - Here is a table of some odd values of y, and corresponding choices - for z which are "good". - - y z r a (hex) max x (hex) - - 3 2**32 1 55555555 100000001 - 5 2**32 1 33333333 100000003 - 7 2**24-1 0 249249 (infinite) - 9 2**24-1 0 1c71c7 (infinite) - 11 2**20-1 0 1745d (infinite) - 13 2**24-1 0 13b13b (infinite) - 15 2**32 1 11111111 10000000d - 17 2**32 1 f0f0f0f 10000000f - - If r is 1, then b = a+r-1 = a. This simplifies the computation - of (ax+b), since you can compute (x+1)(a) instead. If r is 0, - then b = 0 is ok to use which simplifies (ax+b). - - The bit patterns for 55555555, 33333333, and 11111111 are obviously - very regular. The bit patterns for the other values of a above are: - - y (hex) (binary) - - 7 249249 001001001001001001001001 << regular >> - 9 1c71c7 000111000111000111000111 << regular >> - 11 1745d 000000010111010001011101 << irregular >> - 13 13b13b 000100111011000100111011 << irregular >> - - The bit patterns for (a) corresponding to (y) of 11 and 13 may be - too irregular to warrant using this method. - - When z is a power of 2 minus 1, then the division by z is slightly - more complicated, involving an iterative solution. - - The code presented here solves division by 1 through 17, except for - 11 and 13. There are algorithms for both signed and unsigned - quantities given. - - TIMINGS (cycles) - - divisor positive negative unsigned - - . 1 2 2 2 - . 2 4 4 2 - . 3 19 21 19 - . 4 4 4 2 - . 5 18 22 19 - . 6 19 22 19 - . 8 4 4 2 - . 10 18 19 17 - . 12 18 20 18 - . 15 16 18 16 - . 16 4 4 2 - . 17 16 18 16 - - Now, the algorithm for 7, 9, and 14 is an iterative one.

Note that z will be - chosen so that division by z is cheap. - - Let r be the remainder(z/y). In other words, r = z - ay. - - Now, our method is to choose a value for b such that - - q'(x) = floor((ax+b)/z) - - is equal to q(x) over as large a range of x as possible. If the - two are equal over a sufficiently large range, and if it is easy to - form the product (ax), and it is easy to divide by z, then we can - perform the division much faster than the general division algorithm. - - So, we want the following to be true: - - . For x in the following range: - . - . ky <= x < (k+1)y - . - . implies that - . - . k <= (ax+b)/z < (k+1) - - We want to determine b such that this is true for all k in the - range {0..K} for some maximum K. - - Since (ax+b) is an increasing function of x, we can take each - bound separately to determine the "best" value for b. - - (ax+b)/z < (k+1) implies - - (a((k+1)y-1)+b < (k+1)z implies - - b < a + (k+1)(z-ay) implies - - b < a + (k+1)r - - This needs to be true for all k in the range {0..K}. In - particular, it is true for k = 0 and this leads to a maximum - acceptable value for b. - - b < a+r or b <= a+r-1 - - Taking the other bound, we have - - k <= (ax+b)/z implies - - k <= (aky+b)/z implies - - k(z-ay) <= b implies - - kr <= b - - Clearly, the largest range for k will be achieved by maximizing b, - when r is not zero. When r is zero, then the simplest choice for b - is 0. When r is not 0, set - - . b = a+r-1 - - Now, by construction, q'(x) = floor((ax+b)/z) = q(x) = floor(x/y) - for all x in the range: - - . 0 <= x < (K+1)y - - We need to determine what K is. Of our two bounds, - - . b < a+(k+1)r is satisfied for all k >= 0, by construction. - - The other bound is - - . kr <= b - - This is always true if r = 0. If r is not 0 (the usual case), then - K = floor((a+r-1)/r), is the maximum value for k. - - Therefore, the formula q'(x) = floor((ax+b)/z) yields the correct - answer for q(x) = floor(x/y) when x is in the range - - (0,(K+1)y-1) K = floor((a+r-1)/r) - - To be most useful, we want (K+1)y-1 = (max x) >= 2**32-1 so that - the formula for q'(x) yields the correct value of q(x) for all x - representable by a single word in HPPA. - - We are also constrained in that computing the product (ax), adding - b, and dividing by z must all be done quickly, otherwise we will be - better off going through the general algorithm using the DS - instruction, which uses approximately 70 cycles. - - For each y, there is a choice of z which satisfies the constraints - for (K+1)y >= 2**32. We may not, however, be able to satisfy the - timing constraints for arbitrary y. It seems that z being equal to - a power of 2 or a power of 2 minus 1 is as good as we can do, since - it minimizes the time to do division by z. We want the choice of z - to also result in a value for (a) that minimizes the computation of - the product (ax). This is best achieved if (a) has a regular bit - pattern (so the multiplication can be done with shifts and adds). - The value of (a) also needs to be less than 2**32 so the product is - always guaranteed to fit in 2 words. - - In actual practice, the following should be done: - - 1) For negative x, you should take the absolute value and remember - . the fact so that the result can be negated. This obviously does - . not apply in the unsigned case. - 2) For even y, you should factor out the power of 2 that divides y - . and divide x by it. You can then proceed by dividing by the - . odd factor of y. - - Here is a table of some odd values of y, and corresponding choices - for z which are "good". - - y z r a (hex) max x (hex) - - 3 2**32 1 55555555 100000001 - 5 2**32 1 33333333 100000003 - 7 2**24-1 0 249249 (infinite) - 9 2**24-1 0 1c71c7 (infinite) - 11 2**20-1 0 1745d (infinite) - 13 2**24-1 0 13b13b (infinite) - 15 2**32 1 11111111 10000000d - 17 2**32 1 f0f0f0f 10000000f - - If r is 1, then b = a+r-1 = a.
