Binary files in an executable file system can be directly executed by the
central processing unit at the location in which the binary files are
stored. A pre-runtime tool can traverse a replica directory hierarchy in
a host/loading computer to fill an internal data structure which can be
used to generate a binary file that can be loaded directly into the
embedded computer. The central processing unit (CPU) and its components
such as the address bus, data bus, and program counter, can directly
interact with unit of storage interface mechanisms, such as read/write
means, identifying location means, and concatenation means. In some
embodiments, the page size in the memory management unit (MMU) of the CPU
is set to the same size as the unit of storage.
