www.nxp.comAudio DSP CPUs Two coprocessors for the Cortex-M33: a hardware accelerator for fixed and floating point DSP functions (PowerQuad) and a Crypto/FFT engine (Casper). The DSP coprocessor uses a bank of four dedicated 2 KB SRAMs. The Crypto/FFT engine uses a bank of two 2 KB SRAMs that are also AHB accessible by the CPU and the DMA engine.
Digital signal processing for STM32 microcontrollers using ...
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
The DSP capabilities of ARM -M4 and Cortex-M7 Processors
community.arm.comWhile Cortex-M4 and Cortex-M7 can be used in DSP applications for both fixed-point and floating-point operations, the DSP extension is optimized for fixed-point applications. Floating-point operations are accelerated using the optional floating-point unit.

Digital signal processor fundamentals and system design
cds.cern.chinclude TIÕs TMS3 20C20 and MotorolaÕs DSP56002. 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.

Interrupts C - Uppsala University
www.signal.uu.seThe fixed- and floating-point exceptions are triggered by the corresponding bits in the STKY register. It is possible that one of these interrupts occurred during normal program operation. Be careful when you setup a signal handler to deal with these interrupts. C.3 ANSI C INTERRUPTS
Floating-Point Operator v7 - Xilinx
www.xilinx.comFloating-Point Operator core treats all NaNs as Quiet NaNs. When any NaN is supplied as one of the operands to the core, the result is a Quiet NaN, and an invalid operation exception is not raised (as would be the case for signaling NaNs). The exceptions to this rule are floating-point to fixed-point conversion and the absolute value operator.
