Introduction
In Constant Coefficient mode, a single coefficient set can be programmed into field programmable gate
array (FPGA) fabric. In Multiple Constant Coefficient mode, the multiple constant coefficient sets can be
programmed, and the FPGA stores all of them. It is possible to switch between the pre-loaded sets at any
moment during runtime, thus changing the filter impulse response. In Reloadable Coefficient mode, the
coefficients can be reloaded at the runtime.
Internal filter processing takes place at full precision to reduce truncation or rounding noise and to avoid a
risk of overflow. The filtered results are presented in full precision as well.
Figure 2 shows an example of using a FIR filter. Digital samples to be filtered enter the filter input and
filtered samples appear at the filter output.
