0x157C

0x157C is a hexadecimal numeral that equals 5484 in decimal notation. The format, which prefixes the value with "0x", is commonly employed in computer programming and digital electronics to indicate that the following digits represent a base‑16 number. In many contexts the value 0x157C appears as an address, offset or constant.

In firmware and operating system development, 0x157C may be used as a memory address range within system BIOS structures or as an offset in data tables. In debugging tools, a symbol name may be resolved to this address, indicating the location of a particular routine or data area in a core image. In embedded systems, the number can represent a register address for peripheral control.

In software applications the constant 0x157C can serve as a configuration value, such as a mode flag or a feature toggle, encoded as part of a larger configuration word. In cryptographic contexts, the value may appear in message authentication codes or as part of a key schedule, though it is typically combined with other data.

Because the identifier is a low‑level number, it is not tied to a single standard or protocol. Rather, it appears in multiple technical documents and source code bases, generally wherever hexadecimal addressing or constant definitions are required. For this reason, references to 0x157C are most frequently found in technical notes, source code comments, and firmware release notes rather than in high‑level documentation.
