Cpp CodeGen is a C++ code generation library package that allows developers to write more efficient code. The library generates code that is optimized for speed and performance, while allowing developers to focus on the functionality of their applications.
Example 1 - Matrix Multiplication This example uses the Cpp CodeGen library to generate code for a matrix multiplication operation. The code generated by the library is optimized for speed and efficiency, allowing the multiplication to be performed quickly even for large matrices.
// Matrix multiplication using Cpp CodeGen #include
void matrix_mult(float* A, int A_rows, int A_cols, float* B, int B_rows, int B_cols, float* C) { // Generate code for matrix multiplication CppCodeGen codegen("matrix_mult"); std::stringstream s; s << "for(int i = 0; i < " << A_rows << "; i++) {"; s << "for(int j = 0; j < " << B_cols << "; j++) {"; s << "float sum = 0;"; s << "for(int k = 0; k < " << A_cols << "; k++) {"; s << "sum += A[i*A_cols + k] * B[k*B_cols + j];"; s << "}"; s << "C[i*B_cols + j] = sum;"; s << "}"; s << "}"; codegen.generate(s.str()); codegen.execute(A, B, C); }
Example 2 - Image Processing This example uses the Cpp CodeGen library to generate code for an image processing operation. The code generated by the library is optimized for speed and efficiency, allowing the processing to be performed quickly even for large images.
// Image processing using Cpp CodeGen #include
void gaussian_blur(unsigned char* image, int width, int height) { // Generate code for Gaussian blur CppCodeGen codegen("gaussian_blur"); std::stringstream s; s << "int kernel[5][5] = {"; s << "{1, 4, 6, 4, 1},"; s << "{4, 16, 24, 16, 4},"; s << "{6, 24, 36, 24, 6},"; s << "{4, 16, 24, 16, 4},"; s << "{1, 4, 6, 4, 1}"; s << "};"; s << "for(int y = 2; y < " << height - 2 << "; y++) {"; s << "for(int x = 2; x < " << width - 2 << "; x++) {"; s << "int sum = 0;"; s << "for(int i = -2; i <= 2; i++) {"; s << "for(int j = -2; j <= 2; j++) {"; s << "sum += kernel[i+2][j+2] * image[(y+i)*width + (x+j)];"; s << "}"; s << "}"; s << "image[y*width + x] = sum / 256;"; s << "}"; s << "}"; codegen.generate(s.str()); codegen.execute(image, width, height); }
Package Library - The Cpp CodeGen library is a standalone library packaged as a header-only library. It does not rely on any external packages or libraries.
