Data structure to hold floating point formatter settings for the floating point number generation.
| uint8_t mykonosFloatPntFrmt_t::dataFormat |
These parameter sets the format of the 16-bit output on the JESD interface: Setting this to 1 then the format is from MSB to LSB to {sign, significand, exponent}. Clearing this bit sets the format to {sign, exponent, significand}.
| uint8_t mykonosFloatPntFrmt_t::encNan |
if this parameter is set to 1 then the floating point formatter reserves the highest value of exponent for NaN to be compatible to the IEEE754 specification. Clearing this parameter increases the range of the exponent by one.
| uint8_t mykonosFloatPntFrmt_t::expBits |
These parameter is used to indicate the number of exponent bits in the floating point number according to the following settings:
| expBits | Round type |
|---|---|
| 0 | 2 bit exponent, 13 bit significand, 1 bit sign |
| 1 | 3 bit exponent, 12 bit significand, 1 bit sign |
| 2 | 4 bit exponent, 11 bit significand, 1 bit sign |
| 3 | 5 bit exponent, 10 bit significand, 1 bit sign |
| uint8_t mykonosFloatPntFrmt_t::leading |
Setting this parameter hides the leading one in the the significand to be compatible to the IEEE754 specification. Clearing this parameter causes the leading one to be at the MSB of the significand.
| uint8_t mykonosFloatPntFrmt_t::roundMode |
These parameter set the round modes for the significand. The following settings are defined in the IEEE754 specification:
| roundMode | Round type |
|---|---|
| 0 | RoundTiesToEven |
| 1 | RoundTowardsPositive |
| 2 | RoundTowardsNegative |
| 3 | RoundTowardsZero |
| 4 | RoundTiesToAway |
