Floating-point is required, so you'd probably need a different
processor. This runs on a cheap general purpose processor with FP, like
the STM32F4 clocked at 160 MHz, and isn't written to use the special
features of a DSP. That STM processor has enough power left over to run
the HF modem.
MIPS are only loosely related to the performance of a processor. So any
number we gave you would be wrong for most architectures.
Thanks
