摘要： The present invention provides an apparatus and method to reduce the memory footprint of a processor architecture by structuring processor code to be stored in an external device, and transferring into the processor certain code and associated data as it is needed. The processor code or algorithm is divided into a controlling piece and a working piece. The controlling piece can be located on a low-MIPS, high memory-footprint device, whereas the working piece can be located on a high-MIPS, low memory-footprint device. The working piece can also be broken down into phases or segments, which are put in a data store. The segments are then transferred, on an as-needed basis along with associated data, from the store into the constrained memory of the low memory-footprint device. Transfer is facilitated by a segment manager which can be processed from the low-MIPS device, or alternatively from the high-MIPS device.

摘要： The present invention provides a method for use with program overlays, wherein code segments, along with data segments pertaining to the code segments, are transferred into a receiving memory segment. Program code is separated into common code and overlay code. The overlay code is then broken down into segments according to functionality, and the need to create segments that will fit into a receiving memory segment. An overlay control file is created for each segment, then a wrapper file. Linker command files are created for the common area and code area. The wrapper files and linker command files are used to create a common image file for the code/data. The common image is used to produce overlay sections, which are then concatenated together into one file. This one file is then loaded into memory for transfer of the overlays to a receiving memory area.
摘要翻译：本发明提供了一种与程序覆盖层一起使用的方法，其中代码段以及与代码段有关的数据段被传送到接收存储器段中。程序代码分为通用代码和重叠代码。然后，覆盖代码根据功能被分解成段，并且需要创建适合于接收存储器段的段。为每个段创建一个覆盖控制文件，然后创建一个包装文件。链接器命令文件是为公共区域和代码区域创建的。包装文件和链接器命令文件用于为代码/数据创建一个公共映像文件。公共图像用于产生覆盖部分，然后将它们连接在一起成为一个文件。然后将该一个文件加载到存储器中，以将覆盖层传送到接收存储器区域。
