Patent number: 7810088Abstract: A wireless communication device capable of downloading a software update file from a wireless network. The wireless communication device comprises a non-volatile memory that is re-programmed by sectors. The non-volatile memory stores: i) a target file to be updated, ii) the downloaded software update file, and iii) a journal comprising a plurality of entries, each of the entries containing status information associated with a re-programmed sector of the non-volatile memory. The wireless communication device also comprises a random access memory and a main processor that replaces target code in the target file with replacement code from the downloaded software update file. The main processor creates a first block of replacement code in the random access memory and re-programs a first target sector of the non-volatile memory by storing the first block of replacement code into the first target sector.Type: GrantFiled: June 20, 2003Date of Patent: October 5, 2010Assignee: Samsung Electronics Co., Ltd.Inventors: Sudhindra P.

Patent number: 7735075Abstract: The present disclosure relates generally to a system and method for a pseudo DLL linker. In one example, the method includes identifying a plurality of components forming an image and identifying all symbols exportable from each component and all symbols imported by each component from another component. A redirection mechanism is built containing an address of each symbol exported by a component that is imported by another component, and each component is modified to alter each direct reference to a symbol associated with another component to a reference to the redirection mechanism. A linker is called to link a final image based on the modified components.Type: GrantFiled: January 18, 2006Date of Patent: June 8, 2010Assignee: Samsung Electronics Co., Ltd.Inventors: Guoxin Fan, Vani Budhati, Roger Ingles
