www.st.comDSP operations can use either floating-point or fixed-point formats. 1.1.1 Floating point Floating point is a method to represent real numbers. The floating point unit in the Cortex®-M4 is only single precision, as it includes an 8-bit exponent field and a 23-bit fraction, for a total of 32 bits (see Figure 1). The floating point

While the first DSPs were capable of fixed-point operations only, towards the end of the 1980s DSPs with floating point capabilities started to appear. Examples are MotorolaÕs DSP96001 and TIÕs TMS320C30. It should be noted that the floating-point format was not always IEEE-compatible.

www.agner.orgAug 17, 2021 · clock counts considerably. Floating point operands are presumed to be normal num-bers. Denormal numbers, NAN's and infinity may increase the latencies by possibly more than 100 clock cycles on many processors, except in move, shuffle and Boolean instructions. Floating point overflow, underflow, denormal or NAN results may give a similar delay.
