Hard-set parameters for the Xylo IMU HDK

Module Attributes

B_WORST_CASE	Number of additional bits devoted to storing filter taps such that no over- and under-flow can happen
CLOCK_RATE	Fixed computation step rate of 200Hz for Xylo IMU
COV_EXTRA_BIT	The components of the covariance can enlarger by a factor 3 (at most), thus, an additional register size of 2
DEFAULT_FILTER_BANDS	Default passbands for the IMUIF Filters
FILTER_ORDER	Filter order of the Xylo-IMU filters
N_CHANNEL	Fixed number of channels employed
NROUND	number of round rotation computation and update is done over all 3 axes/dims
NUM_ANGLES	number of angles in lookup table
NUM_BITS	number of bits in the continuous signal(input, obtained after rotation removal).
NUM_BITS_COVARIANCE	number of bits used for the covariance matrix
NUM_BITS_HIGHPREC_FILTER_BASE	This is the base value.
NUM_BITS_MULTIPLIER	number of bits devoted to computing [x(t) x(t)^T]_{ij}.
NUM_BITS_ROTATION	number of bits devoted for implementing rotation matrix
NUM_BITS_SPIKE	number of bits devoted to storing the output spike encoding
ROT_EXTRA_BIT	Rotation can expand at most by a factor during the multiplication, thus, an additional register size of 1
