UWtype -- An unsigned type, default type for operations (typically a "word")

UQItype -- Unsigned 8 bit type.

DItype, UDItype -- Signed and unsigned 64 bit types.

|
|
1) umul_ppmm(high_prod, low_prod, multiplier, multiplicand) multiplies two
|
| 50 |
|
|
UWtype integers MULTIPLIER and MULTIPLICAND, and generates a two UWtype
|
| 51 |
|
|
word product in HIGH_PROD and LOW_PROD.
|
| 52 |
|
|
|
| 53 |
|
|
2) __umulsidi3(a,b) multiplies two UWtype integers A and B, and returns a
|
| 54 |
|
|
UDWtype product. This is just a variant of umul_ppmm.
|
| 55 |
|
|
|
| 56 |
|
|
3) udiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
|
| 57 |
|
|
denominator) divides a UDWtype, composed by the UWtype integers
|
| 58 |
|
|
HIGH_NUMERATOR and LOW_NUMERATOR, by DENOMINATOR and places the quotient
|
| 59 |
|
|
in QUOTIENT and the remainder in REMAINDER. HIGH_NUMERATOR must be less
|
| 60 |
|
|
than DENOMINATOR for correct operation. If, in addition, the most
|
| 61 |
|
|
significant bit of DENOMINATOR must be 1, then the pre-processor symbol
|
| 62 |
|
|
UDIV_NEEDS_NORMALIZATION is defined to 1.
|
| 63 |
|
|
|
| 64 |
|
|
4) sdiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
|
| 65 |
|
|
denominator). Like udiv_qrnnd but the numbers are signed. The quotient
|
| 66 |
|
|
is rounded towards 0.
|
| 67 |
|
|
|
| 68 |
|
|
5) count_leading_zeros(count, x) counts the number of zero-bits from the
|
| 69 |
|
|
msb to the first nonzero bit in the UWtype X. This is the number of
|
| 70 |
|
|
steps X needs to be shifted left to set the msb. Undefined for X == 0,
|
| 71 |
|
|
unless the symbol COUNT_LEADING_ZEROS_0 is defined to some value.
|
| 72 |
|
|
|
| 73 |
|
|
6) count_trailing_zeros(count, x) like count_leading_zeros, but counts
|
| 74 |
|
|
from the least significant end.
|
| 75 |
|
|
|
| 76 |
|
|
7) add_ssaaaa(high_sum, low_sum, high_addend_1, low_addend_1,
|
| 77 |
|
|
high_addend_2, low_addend_2) adds two UWtype integers, composed by
|
| 78 |
|
|
HIGH_ADDEND_1 and LOW_ADDEND_1, and HIGH_ADDEND_2 and LOW_ADDEND_2
|
| 79 |
|
|
respectively. The result is placed in HIGH_SUM and LOW_SUM. Overflow
|
| 80 |
|
|
(i.e. carry out) is not stored anywhere, and is lost.
|
| 81 |
|
|
|
| 82 |
|
|
8) sub_ddmmss(high_difference, low_difference, high_minuend, low_minuend,
|
| 83 |
|
|
high_subtrahend, low_subtrahend) subtracts two two-word UWtype integers,
|
| 84 |
|
|
composed by HIGH_MINUEND_1 and LOW_MINUEND_1, and HIGH_SUBTRAHEND_2 and
|
| 85 |
|
|
LOW_SUBTRAHEND_2 respectively. The result is placed in HIGH_DIFFERENCE
|
| 86 |
|
|
and LOW_DIFFERENCE. Overflow (i.e. carry out) is not stored anywhere,
|
| 87 |
|
|
and is lost.
|
| 88 |
