561 | because we are not operating on one word at a time. | |

564 | _______________________ |
565 | [__op0_high_|__op0_low__] | |
566 | _______________________ | |
567 | * [__op1_high_|__op1_low__] | |

571 | _______________________ | |
572 | (2a) [__op0_low__*__op1_high_] | |
573 | _______________________ | |
574 | (2b) [__op0_high_*__op1_low__] | |
575 | _______________________ | |
576 | (3) [__op0_high_*__op1_high_] | |
77c9c6c2 RK |
577 | |
578 | ||
579 | This gives a 4-word result. Since we are only interested in the | |
580 | lower 2 words, partial result (3) and the upper words of (2a) and | |
581 | (2b) don't need to be calculated. Hence (2a) and (2b) can be | |
582 | calculated using non-widening multiplication. | |
583 | ||
584 | (1), however, needs to be calculated with an unsigned widening | |
585 | multiplication. If this operation is not directly supported we | |
586 | try using a signed widening multiplication and adjust the result. | |
587 | This adjustment works as follows: | |
588 | ||
589 | If both operands are positive then no adjustment is needed. | |
590 | ||
591 | If the operands have different signs, for example op0_low < 0 and | |
592 | op1_low >= 0, the instruction treats the most significant bit of | |
593 | op0_low as a sign bit instead of a bit with significance | |
594 | 2**(BITS_PER_WORD-1), i.e. the instruction multiplies op1_low | |
595 | with 2**BITS_PER_WORD - op0_low, and two's complements the | |
596 | result. Conclusion: We need to add op1_low * 2**BITS_PER_WORD to | |
597 | the result. | |
598 | ||
599 | Similarly, if both operands are negative, we need to add | |
600 | (op0_low + op1_low) * 2**BITS_PER_WORD. | |
601 | ||
602 | We use a trick to adjust quickly. We logically shift op0_low right | |
603 | (op1_low) BITS_PER_WORD-1 steps to get 0 or 1, and add this to | |
604 | op0_high (op1_high) before it is used to calculate 2b (2a). If no | |
605 | logical shift exists, we do an arithmetic right shift and subtract | |
606 | the 0 or -1. */ | |
