If combined with general mobile phones, Becoming a personal digital assistant with a mobile phone function. If combined with a personal computer, it becomes a personal digital assistant with an Internet messaging function. The concept of such things is endless. At present, among these electronic communication devices, many products already have the function of downloading applications on the Internet, and the compilation system of these electronic communication devices, when downloading applications, the processing methods can generally be divided into the following Two types: 1. For each downloaded application program, a variety of connection addresses can be provided for downloading, so that the compilation system can download the corresponding address code from the application program according to actual needs. 2. A certain area needs to be reserved in the system memory space. When the compilation system wants to execute the downloaded application, it can be copied to this area and then executed. According to the aforementioned compilation system of the traditional electronic communication device, in the process of downloading the application program, there are some unsatisfactory and troublesome shortcomings in its processing method. ® When processing ', because the compilation system needs to leave different positions for these applications ~ address segments, so that each application can generate corresponding address codes for different address segments, which means that if The compilation system allocates ten address segments for use by ten applications. Each application needs to generate ten types of code corresponding to the ten addresses for the compilation system to use when downloading these applications. In particular, during subsequent collation of the downloaded application, if the application needs to be moved to another position a: segment '尙 need to re-download other codes that match the other address segment, causing the application to It is extremely inconvenient to maintain and organize. In addition, the application downloaded by the second method mentioned above needs to be copied to the reserved area every time it is executed, and then executed. , Resulting in a very slow pace of implementation of the application, this 2- (please read the back of the precautions to fill out this page), Φ

Brief description of the figure: Figure 1 is a schematic diagram of the instruction replacement process of the present invention. Figure 2 is a schematic diagram of the interrupt service process of the present invention. Detailed description: The present invention is mainly applied to an electronic communication device for downloading application programs on a network or a personal computer. The electronic communication device may be a cellar phone or a personal digital assistant. Personal Digital Assistant or other electronic communication device. The electronic communication device is provided with a microprocessor. The microprocessor is used to control the electronic components on the communication device so that these components can operate normally. It is connected to a server or personal computer of the Internet, and an application program is downloaded from the network through a compilation system of the microprocessor. The invention enables the compilation system to divide an overall area in its memory for use by downloaded applications, and the application can be stored at any address in the area for full and flexible use The system memory space, and when the compiler downloads the application program, it can modify the operation instructions for direct addressing to the correct address, perform the addressing operation, and the operation instructions for addressing can be used. Software Interrupt (SWI) is used as a bridge to replace these instructions, so as to obtain the correct address required by the compilation system for indirect addressing operations. In a preferred embodiment of the present invention, a microprocessor numbered T900 designed and produced by Toshiba Co., Ltd. is used as an example to illustrate the design concept and operation flow of the present invention as follows: The compiler system used in the microprocessor Among the various instructions, there are three types of address-related instructions. -4- This paper size applies to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) (Please read the precautions on the back before filling this page)- ------- Order --------- line— ▲ Printed by the Employees 'Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 480445 A7 B7 Printed by the Employees' Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 5. Description of the invention) LD There are three types: JP, CALL, and others. Among them, LD instructions include global variables and constants of the system. JP instructions are used to directly modify the IP (instructioon pointer) to change the processing flow. CALL · instructions are It is used to push the current IP into the stack, and then modify the IP to point it to the calling address. When it returns to the main program, it retrieves the IP address from the stack and restores the original address. The JP The difference between CALL and CALL instructions is the CALL instruction More IP of preservation and restoration. Since these instructions have a great impact on the data operation and processing flow, if the three types of instructions can be handled properly, the compilation system can smoothly and correctly download applications from the Internet. In the present invention, for LD-type instructions, global variables and constants can be stored in a fixed area during program execution. In this way, LD-type instructions can be properly processed easily. As for the instructions of JP and CALL, they can be divided into direct addressing (such as: JP 400000H, CALL 440000H ...) and indirect addressing (such as: JP XWA, CALL XHL ...) There are two kinds of instructions. Among them, the direct addressing instruction can directly modify the address in the code to the correct address in the process of downloading or moving the application, and during the downloading process, the program automatically generates an index. A file is used to record the address sought by the instruction. In this way, the program can be executed faster than Shaanxi. Because in the T900 microprocessor, between the JP and CALL instructions, the CALL instruction needs to return to the main program, so there are more actions for saving and restoring IP. Therefore, the compiler system of the microprocessor will be converted into Assembler. When the program is executed, the parameters are pushed into the stack one by one, and the action of CALL is executed. After returning to the main program, the parameters are pushed out of the stack one by one. The present invention utilizes this concept to provide an instruction SWI in the compilation system, and a software interrupt is generated by the instruction SWI. The execution process of the software interrupt is to push the IP stack and press the flag register (SR). After the stack, the pointer is pointed to the corresponding interrupt entry address, and when returning to the main program, the flag register (SR) is popped from the stack, and then the IP is popped from the stack. For the indirect addressing instructions of the present invention, the addressing mode of the register can be used to explain. Such instructions include JP < CC >, MEM and CALL < CC >, MEM, etc., where MEM is a register,- 5 · This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) " " ~ " (Please read the precautions on the back before filling this page) · Order ------- --line!

Instruction replacement processing: Refer to Figure 1, during the download process of the application, Scanning the downloaded binary code is completed. When JP < CC >, MEM or CALL < CC >, MEM is found, it is replaced by SWI, and a type number is placed after the type number. This type number is preset by the present invention. The number is used to define different instructions by different type numbers. When the present invention performs subsequent processing, it knows the original operation mode. As for the remaining bytes, it is like a NOP input. 2. Interrupt service processing: see Figure 2 As shown, provide an interrupt service function to make the program After going to SWI, jump to the corresponding interrupt entry address, execute the service function, and take out the contents of the corresponding register according to the type number, and modify it to the correct one, such as: add an offset, The offset can be calculated based on the address where the application is placed, and then put the stack as the return address of the SWI into the stack, so that when the interrupt returns, it will jump to the address required by the present invention If it is a CALL type instruction, the present invention does not need to insert the return address of CALL · into the stack first, for example, add 1 to the original return address of SWI in the stack before modification, or it can be calculated based on the type number. In the process of the foregoing instruction replacement process, the present invention mainly scans the downloaded binary code, and performs the following steps, referring to FIG. 1, to replace the related instructions: (1.1) reading an instruction; (1.2) Determine whether the addressing mode of the instruction is an absolute jump or absolute call, that is, whether it is direct addressing. If so, continue with the following steps, otherwise, go to step (1.4); (1.3) If it is direct addressing, Required by the directive Change the jumped address directly to the correct address, and enter step (1.8); This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) • Order --------- line d (Please read the precautions on the back before filling this page) --- ^ ---------------------- Suppress 0445 A7 B7 V. Description of the invention (g) (1.4) If it is not direct addressing, then determine whether it is a jump or call between registers? If yes, continue with the following steps, otherwise, go to step (1.8); (1 · 5) If it is a register search Address, different instructions are converted into different type numbers. The type number is a preset number of the present invention to define different instructions by different type numbers; (1 · 6) change the first byte of the instruction It becomes a software interrupt mark SWI; (1.7) Change the second byte of the instruction to the type number; (1.8) Determine whether the scanning of the binary code is finished? If 尙 is not completed, return to step (1.1) and take the next instruction until the scan is finished, otherwise, the procedure of replacing the instruction is ended. In the aforementioned interrupt service processing flow, the present invention mainly provides an interrupt service function. After the program executes SWI, it jumps to the corresponding interrupt entry and executes the interrupt according to the following steps, referring to FIG. 2 again. Service functions: (2.1) First, save all the contents of the register to a custom variable, which means that it can be stored in the memory space, so that the program can still run correctly after the interrupt return; (2.2) Pop the flag register (SR) out of the stack, save it, so that it can be restored in subsequent programs, and then pop the interrupt return address out of the stack, so that it can be modified into a new return address and put into the stack in subsequent programs; (2.3) Read the type number; (2.4) According to the type number, determine whether the instruction is a CALL · type instruction? If yes, continue with the following steps, otherwise, go to step (2 · 6); (2.5) If it is a CALL instruction, make a profit as described above, because the CALL instruction needs to return to the original program after execution, so it needs to be returned at this time. The address is the return address of the SWI in the stack before it was originally modified. It is added to the stack later, and is saved later. (2.6) Read out the corresponding register in the register according to the type number and modify it.

In this way, the compiling system of the electronic communication device only needs to divide an overall area in the memory space, so that the downloaded application program can be stored at any address in the area, without having to reserve a special space to execute the download In this way, when the application is executed, there is no need to copy it, which can effectively improve the execution efficiency and speed. At the same time, the downloaded application is not limited by the size of the reserved space. In addition, because the compilation system does not need to allocate multiple address segments for downloaded applications, the arrangement of these applications is not only subject to address constraints, but also within the scope of the umbrella area. The number is not limited, which greatly improves the convenience in use. In addition, because the compilation system uses software interrupts to complete the indirect addressing operation, it can be easily implemented without adding additional hardware equipment. 'The above descriptions are only the best specific examples of the present invention, but the features of the present invention are not limited to this. Any person skilled in the art can easily think of changes or modifications in the field of the present invention. All should be covered by the following patent application scope of the present invention. __- 8- This paper size thorn + S ® home standard (CNS) A4 specification (210 X 297 public love) (Please read the precautions on the back before filling this page) IAW -------- Order-- -------line.
