Detailed Description

[bfp_complex_s32_t]

A block floating-point vector of complex 16-bit elements.

Initialized with the bfp_complex_s16_init() function.

The logical quantity represented by each element of this vector is: data[k].re * 2^(exp) + i * data[k].im * 2^(exp) where the multiplication and exponentiation are using real (non-modular) arithmetic, and i is sqrt(-1)

The BFP API keeps the hr field up-to-date with the current headroom of data[] so as to minimize precision loss as elements become small. [bfp_complex_s16_t]
