I'm interested in the claimed real-time capabilities, but it's hard to find anything about them written there. Still, I like the hardware integration.

yeah the claim is ambiguous because the beam itself is only guaranteed soft real time, leaving it open ended might make ppl think hard real-time especially since its hardware

They support writing RTOS tasks in C as I understand it.

Real-time is some of the most misused jargon in modern history.

In general, most JIT or VM can't even claim guaranteed latency. People that mix these concepts betray their ignorance while seeming intelligent.

FreeRTOS is small and feasible.

VxWorks if your budget is unconstrained.

LinuxRT kernel (used in LinuxCNC) with external context clocking, and or FPGA memory DMA overlap module (zynq SoC etc.)

Real-time is a specialized underpaid area, and most people have too abstract of an understanding of hardware to tackle metastability problems. =3
