Description
Teensy 4.1’s Cortex-M7 processor includes a floating point unit (FPU) which supports both 64 bit “double” and 32 bit “float”. With M4’s FPU on Teensy 3.5 & 3.6, and also Atmel SAMD51 chips, only 32 bit float is hardware accelerated. Any use of double, double functions like log(), sin(), cos() means slow software implemented math. Teensy 4.1 executes all of these with FPU hardware.
