Hello Martin, The FPU on the F28004x is the same as the FPU32 used on the latest Delfino series: F2837x. Compared to previous FPUs like on the F28335 or the F2806x series, the new FPU includes native instructions for support trigonometric math. Yes there are single cycle SINE, COSINE and ARCTAN instructions added to the unit along with a native SQRT for magnitude calculations. Consider reviewing the C2000 Accelerators Whitepaper and the Technical Reference Manuals for these devices for more details. Accelerators: Enhancing the Capabilities of the C2000 MCU Family (Rev. A) I hope this helps!
