Get a bit from an array of unsigned integers. The integers are arranged in little-endian order.
| lhs | The array of integers from which to take the bit. |
| index | The index of the bit |
Set a bit from an array of unsigned integers. The integers are arranged in little-endian order.
| r | The array of integers on which to set the bit. |
| index | The index of the bit |
| value | The value of the bit, either 0 or 1. |
Shift logical left with carry chain.
| lhs | The original value |
| rhs | The count by how much to shift lhs left. |
| carry | The carry data to or with the lower bits. |
Shift logical right with carry chain.
| lhs | The original value |
| rhs | The count by how much to shift lhs right. |
| carry | The carry data to or with the lower bits. |
Shift arithmetic right with carry chain.
| lhs | The original value |
| rhs | The count by how much to shift lhs right. |
Add two numbers with carry chain.
| lhs | The left hand side |
| rhs | The right hand side |
| carry | From the previous add in the chain |
Multiply with carry. The carry is a high-word of the multiplication result and has the same size as the inputs. The accumulator is used when doing long-multiplication from the previous row. This function does not overflow even if all the arguments are at max.
| lhs | The left hand side. |
| rhs | The right hand side. |
| carry | The carry-input; carry-output from the previous mul_carry(). |
| accumulator | The column value during a long multiply. |
Wide divide. Can be used to divide a wide unsigned integer by a unsigned integer, as long as the result fits in an unsigned integer.
| lhs_lo | The low side of a wide left-hand-side |
| lhs_hi | The high side of a wide left-hand-side |
| rhs | The right hand side |
Bit scan reverse.
| lhs | The array of unsigned integers to find the highest set bit off. |
| n | The number of unsigned integers in the array. |
Invert unsigned integers using a carry-chain Technically this is not an carry chain.
| r | The result of the inversion. |
| rhs | The right hand side operand. |
| n | The number of digits of r and rhs. |
shift logical right using a carry-chain
| r | The result of the logical-shift-right. |
| lhs | The left hand side operand of the lsr. |
| rhs | The right hand side operand of the lsr, the number of bits to shift. |
| n | The number of digits of r, lhs and rhs. |
shift logical right using a carry-chain
| r | The result of the logical-shift-right. |
| lhs | The left hand side operand of the lsr. |
| rhs | The right hand side operand of the lsr, the number of bits to shift. |
