函数名称：mpihelp_mul_1

函数原型：mpi_limb_t mpihelp_mul_1(mpi_ptr_t res_ptr, mpi_ptr_t s1_ptr, mpi_size_t s1_size, mpi_limb_t s2_limb)

返回类型：mpi_limb_t

参数：

类型参数名称
mpi_ptr_tres_ptr
mpi_ptr_ts1_ptr
mpi_size_ts1_size
mpi_limb_ts2_limb
29  j等于负s1_size
32  s1_ptr减等于j
33  res_ptr减等于j
35  cy_limb等于0
36  循环
37  umul_ppmm(prod_high, prod_low, s1_ptr[j], s2_limb)
38  prod_low加等于cy_limb
39  cy_limb等于如果prod_low小于cy_limb则1否则0加prod_high
40  res_ptr[j]等于prod_low
41  当j先自加循环
43  返回:cy_limb

名称描述
mul_n_basecaseMultiply the natural numbers u (pointed to by UP) and v (pointed to by VP),* both with SIZE limbs, and store the result at PRODP. 2 * SIZE limbs are* always stored. Return the most significant limb.* Argument constraints:* 1
mpih_sqr_n_basecase
mpihelp_mulMultiply the natural numbers u (pointed to by UP, with USIZE limbs)* and v (pointed to by VP, with VSIZE limbs), and store the result at* PRODP. USIZE + VSIZE limbs are always stored, but if the input* operands are normalized
