Detailed Description

Helper class that defines the memory model - internal or user-provided

Parameters:

• max_size - maximal filter length
• max_block - maximal length of the block processing if both parameters are 0, does NOT allocate any memory and instead requires user-provided memory blocks to be passed as parameters.

Not intended to be used directly, so constructor is not exposed

function SetCoefs

inline bool daisysp::FIRMemory::SetCoefs (
    const  float coefs,
    size_t size,
    bool reverse
) 

Configure the filter coefficients

Parameters:

• coefs - pointer to coefficients (tail-first order)
• size - number of coefficients pointed by coefs (filter length)
• reverse - flag to perform reversing of the filter

Returns:

true if all conditions are met and the filter is configured
