 "title": "The ESP32-S3 ULP RISC-V coprocessor runs a tight loop about 482000 times a second, which is roughly a fiftieth of a main core",
 "symptom": "The coprocessor is described as low power without a figure for how much it can actually do, so it is impossible to tell whether a given task fits on it or whether waking a main core is unavoidable.",
