TM4C1290NCPDTI3R / TQFP-128 / Microcontrollers - MCU
The FPU provides three modes of operation to accommodate a variety of applications.
Full-Compliance mode. In Full-Compliance mode, the FPU processes all operations according to the IEEE 754 standard in hardware.
Flush-to-Zero mode. Setting the FZ bit of the Floating-Point Status and Control (FPSC) register enables Flush-to-Zero mode. In this mode, the FPU treats all subnormal input operands of arithmetic CDP operations as zeros in the operation. Exceptions that result from a zero operand are signalled appropriately. VABS, VNEG, and VMOV are not considered arithmetic CDP operations and are not affected by Flush-to-Zero mode. A result that is tiny, as described in the IEEE 754 standard, where the destination precision is smaller in magnitude than the minimum normal value before rounding, is replaced with a zero. The IDC bit in FPSC indicates when an input flush occurs. The UFC bit in FPSC indicates when a result flush occurs.
Default NaN mode. Setting the DN bit in the FPSC register enables default NaN mode. In this mode, the result of any arithmetic data processing operation that involves an input NaN, or that generates a NaN result, returns the default NaN. Propagation of the fraction bits is maintained only by VABS,VNEG, and VMOV operations. All other CDP operations ignore any information in the fraction bits of an input NaN.
