Abstract
A system that determines where a particular XIP component is stored on a medium and loads the component into RAM for execution, providing the ability to demand page specific components at will from storage media, frees up working RAM on memory constrained devices. A Binary File System uses a generic block driver component that loads the XIP code from a block based storage medium. Features of the file system include the ability to load pre-“fixed up” components from a block based device. The invention thus allows an operating system to load code that was previously Executed In Place (XIP) from a block-oriented device.
Claims6
A method for managing memory, comprising:
- storing on a non-linearly addressable memory device, a software component comprising a set of computer-executable instructions, wherein the computer-executable instructions are fixed to be executed from a predefined memory location wherein storing the software component includes taking the computer-executable instructions and placing them in a particular memory location, wherein the instructions are placed in physically contiguous regions of the non-linearly addressable memory;
- loading the set of computer-executable instructions into a linearly addressable memory device using a file system when at least one of the computer-executable instructions is fetched by a processor wherein the instructions are placed in arbitrary regions of the non-linearly addressable memory;
- and
- scanning the non-linearly addressable memory for the instructions by examining the headers of the instructions before loading them into the linearly addressable memory.
