The cores do NOT share an FPU. The M7 core has a built-in FPU capable of single and double precision. The M4 core has its own FPU, capable of only single-precision.
- duskwuff 4y agoWouldn't be the first time that Arduino got basic product specs wrong. They're still advertising the Vidor 4000 [1] as supporting "Mini PCI Express [...] for connecting your FPGA as a peripheral to a computer or to creat [sic] your own PCI interfaces" -- on an FPGA that lacks PCIe support.
