13. DSP Interface for the IIR Filter
The DSP interface for the IIR filter is a unit which covers product addition (
Σ
Bi
×
Yj +
Σ
Am
×
Xn) by hardware.
This interface allows IIR filter calculation to be performed readily and in a high speed.
The DSP interface for the IIR filter has the following features.
Coefficients A and B, and variables X and Y have 16-bit length, and four banks are supported.
(1 to 4) + (1 to 4) product terms can be selected.
Data can be rounded and clipped in units of 10 or 12 bits.
With two or more concatenated banks used, the results of an operation can be transferred to the subsequent
bank register.
Operation time: ((M + N + 1)
