| 13 | * \b Overview | ||
| 14 | * | ||
| 15 | * Computes the Boolean OR operation between two input 32-bit integer vectors. | ||
| 16 | * | ||
| 17 | * <b>Dispatcher Prototype</b> | ||
| 18 | * \code | ||
| 19 | * void volk_32i_x2_or_32i(int32_t* cVector, const int32_t* aVector, const int32_t* | ||
| 20 | * bVector, unsigned int num_points) \endcode | ||
| 21 | * | ||
| 22 | * \b Inputs | ||
| 23 | * \li aVector: Input vector of samples. | ||
| 24 | * \li bVector: Input vector of samples. | ||
| 25 | * \li num_points: The number of values. | ||
| 26 | * | ||
| 27 | * \b Outputs | ||
| 28 | * \li cVector: The output vector. | ||
| 29 | * | ||
| 30 | * \b Example | ||
| 31 | * This example generates a Karnaugh map for the first two bits of x OR y | ||
| 32 | * \code | ||

| 37 | * int32_t* y = (int32_t*)volk_malloc(N*sizeof(int32_t), alignment); | ||
| 38 | * int32_t* z = (int32_t*)volk_malloc(N*sizeof(int32_t), alignment); | ||
| 39 | * int32_t in_seq[] = {0,1,3,2}; | ||
| 40 | * unsigned int jj=0; | ||
| 41 | * for(unsigned int ii=0; ii<N; ++ii){ | ||
| 42 | * x[ii] = in_seq[ii%4]; | ||
| 43 | * y[ii] = in_seq[jj]; | ||
| 44 | * if(((ii+1) % 4) == 0) jj++; | ||
| 45 | * } | ||
| 46 | * | ||
| 47 | * volk_32i_x2_or_32i(z, x, y, N); | ||
| 48 | * | ||
| 49 | * printf("Karnaugh map for x OR y\n"); | ||
| 50 | * printf("y\\x|"); | ||
| 51 | * for(unsigned int ii=0; ii<4; ++ii){ | ||
| 52 | * printf(" %.2x ", in_seq[ii]); | ||

| 59 | * } | ||
| 60 | * printf("%.2x ", z[ii]); | ||
| 61 | * if(!((ii+1) % 4)){ | ||
| 62 | * printf("\n"); | ||
