Embedded System
A specialized computer system built into electronic devices for specific functions. Such systems are typically resource-constrained and have high requirements for real-time behavior and stability.

The HN comments present two voices: one side holds that FP performance is already close enough to C, especially with clear advantages in development efficiency and safety; the other emphasizes that in domains demanding extremely high determinism, such as embedded and real-time systems, C remains irreplaceable.
Embedded systems and IoT devices often write time zone offsets directly into firmware rather than relying on an independently updatable time zone database.
Older embedded devices may not receive time zone patches in a timely manner, becoming a weak link in time synchronization and affecting scenarios such as billing, audit logs, and cross-device event ordering.
In embedded systems, GPU-less server environments, or scientific visualization that requires deterministic output, software rendering is often the more reliable choice.
In some embedded systems and game engines, similar two-ended allocation strategies have been used informally, for example allocating temporary objects and persistent objects from the two ends of the heap respectively to reduce fragmentation, but these practices are usually at the heap level rather than the stack level.
Embedded systems refer to computing systems customized for specific functions and with limited resources, usually running on microcontrollers (MCUs) or embedded Linux, directly controlling hardware such as sensors, motors, and communication modules, and needing to handle real-time performance, power consumption, memory, and hardware timing.
Embedded systems typically have limited memory, are power-sensitive, and need to run stably for long periods; the code generated after C compilation is compact and efficient, enabling it to work in resource-constrained environments.
Embedded devices often run real-time operating systems (RTOS) or deeply customized Linux kernels, with memory ranging from only tens of KB to a few MB, making them unable to support general-purpose security agents.
