  2. Byte addressing - Wikipedia

    en.wikipedia.org/wiki/Byte_addressing

    An eight-bit processor like the Intel 8008 addresses eight bits, but as this is the full width of the accumulator and other registers, this could be considered either byte-addressable or word-addressable. 32-bit x86 processors, which address memory in 8-bit units but have 32-bit general-purpose registers and can operate on 32-bit items with a ...

  4. Java bytecode - Wikipedia

    en.wikipedia.org/wiki/Java_bytecode

    Java bytecode is the instruction set of the Java virtual machine (JVM), the language to which Java and other JVM-compatible source code is compiled. [1] Each instruction is represented by a single byte , hence the name bytecode , making it a compact form of data .

  5. Byte Code Engineering Library - Wikipedia

    en.wikipedia.org/wiki/Byte_Code_Engineering_Library

    The Byte Code Engineering Library (BCEL) is a project sponsored by the Apache Foundation previously under their Jakarta charter to provide a simple API for decomposing, modifying, and recomposing binary Java classes (I.e. bytecode). The project was conceived and developed by Markus Dahm prior to officially being donated to the Apache Jakarta ...

  6. Bytecode - Wikipedia

    en.wikipedia.org/wiki/Bytecode

    Bytecode (also called portable code or p-code) is a form of instruction set designed for efficient execution by a software interpreter.Unlike human-readable [1] source code, bytecodes are compact numeric codes, constants, and references (normally numeric addresses) that encode the result of compiler parsing and performing semantic analysis of things like type, scope, and nesting depths of ...

  7. 64-bit computing - Wikipedia

    en.wikipedia.org/wiki/64-bit_computing

    Hence, a processor with 64-bit memory addresses can directly access 2 64 bytes (16 exabytes or EB) of byte-addressable memory. With no further qualification, a 64-bit computer architecture generally has integer and addressing registers that are 64 bits wide, allowing direct support for 64-bit data types and addresses.

  8. Memory address - Wikipedia

    en.wikipedia.org/wiki/Memory_address

    In theory, modern byte-addressable 64-bit computers can address 2 64 bytes (16 exbibytes), but in practice the amount of memory is limited by the CPU, the memory controller, or the printed circuit board design (e.g., number of physical memory connectors or amount of soldered-on memory).

  9. Bitstream - Wikipedia

    en.wikipedia.org/wiki/Bitstream

    Compression algorithms often code in bitstreams, as the 8 bits offered by a byte (the smallest addressable unit of memory) may be wasteful. Although typically implemented in low-level languages , some high-level languages such as Python [ 1 ] and Java [ 2 ] offer native interfaces for bitstream I/O.
