Library Configuration¶
Configuration Options¶
Iff true, BFP functions will check (assert()) to ensure that each BFP vector argument does not violate any length constraints. Most often this simply ensures that, where BFP functions take multiple vectors as parameters, each of the vectors has the same length.
Defaults to false (0).
The function bfp_sqrt_s16() computes results one bit at a time, starting with bit 14 (the second-to-most significant bit). Because this is a relatively expensive operation, it may be desirable to trade off precision of results for a speed-up.
The time cost of bfp_sqrt_s16() is approximately linear with respect to the depth.
Defaults to XS3_VECT_SQRT_S16_MAX_DEPTH (15)

The function bfp_sqrt_s32() computes results one bit at a time, starting with bit 30 (the second-to-most significant bit). Because this is a relatively expensive operation, it may be desirable to trade off precision of results for a speed-up.
The time cost of bfp_sqrt_s32() is approximately linear with respect to the depth.
Defaults to XS3_VECT_SQRT_S32_MAX_DEPTH (31)

This function is used to dynamically allocate memory. Defaults to malloc. Must have same signature as malloc()
This function is used to deallocate dynamically allocated memory. Defaults to free. Must have same signature as free()

The number of most significant bits which are computed by bfp_s32_sqrt().
See 32-bit BFP Square Root Depth for details.
