This article explains how to reconstruct a 32‑bit floating‑point value from four serial bytes in embedded C by using a union or struct overlay, demonstrates the code, shows the resulting little‑endian byte order, and provides a simple function to detect system endianness.
This article explains the concepts of big‑endian and little‑endian byte ordering, shows memory layout examples with 0x1234, provides C code to display byte order in memory, and discusses how pointer casting behaves differently on each architecture.
This article explains the basic principles of computer architecture, covering CPU operation, memory hierarchy, cache levels, instruction sets, compilation, endianness, and related concepts such as simulators and operating system interactions, illustrating how simple instructions enable complex computations.
This article demonstrates how to determine Go's endianness using unsafe.Pointer and uintptr, explains the memory layout of multi‑byte variables, and details the roles of *T, unsafe.Pointer, and uintptr for pointer arithmetic with concrete code examples.
