Description of Invention () More attention from the public. Because through CE- easy portability of many applications on a series of Windows operating systems, it can make up for the lack of application of the palm transformer and the brain. The existing handheld computer architecture is basically called streamlined The central processing unit (RISC CPU) of Instruction # is the core. Because of its fast operation speed and the most commonly used operation instruction set, it not only has good performance, but also is simple, effective and easy to develop. Furthermore, the architecture of the existing handheld computers follows the structure of the traditional personal computer, that is, the bus structure with the CPU as the core, and uses it to undertake all data processing tasks. Refer to the first figure, which shows the structure of a traditional palm computer. In this figure, the central processing unit (CPU) 100 is composed of two major parts, namely the controller and the processor. The controller provides operation instructions and data 'while the arithmetic unit executes all instructions such as arithmetic and logic operations. In other words, the CPU 1 00 can complete the required data processing tasks. In this figure, the CPU 00 is connected to the memory IO and the chipset 130 via the bus 120. The data can be accessed through the memory u0, and the chipset 130 only plays the role of data exchange and message transmission between the CPU 100 and the edge device. The peripheral devices can be shown in the figure. LCD display 140, touch screen 150, or other input / output device 160, etc. Since the CPU 100 can control the peripheral devices through the chipset 130, the chipset is also an input / wheel-out controller.

At the same time, if you carefully evaluate such handheld computer products, you will find that their speed is too slow will be a fatal injury. In the information society, which is gradually maturing and multimedia data appears in large numbers, too weak computer processing capabilities will inevitably be recognized by consumers. Although the current information products, such as mobile phones with basic computer functions, or handheld computers with camera functions, have been developed, due to the poor hardware architecture, they can only be fixed to a single Function, can not achieve the needs of multi-function. In summary, because the functions of handheld computers are limited by the influence of the hardware structure, they cannot effectively achieve multifunctional and fast information processing capabilities. Therefore, a new handheld computer architecture is still needed to meet the needs of modern people to obtain real-time Information needs. Object and summary of the invention: In view of the above background of the invention, the traditional palmtop computer only uses the central processing unit (CPU) to use the chipset as input / output (I / O) controller, all data processing tasks All are executed by the CPU, thus reducing the processing capabilities of the RISCCPU.

At the same time, in the above hardware configuration, some of the components or devices may be used in common by different domains. For example, the liquid crystal display 4 2 2 shown in Fig. 2 may be shared by the system memory domain 10. Referring to the fifth figure ', this figure illustrates the operation process of the system controller of the palmtop computer system according to the present invention. It was mentioned above that in the multimedia domain 30, each multimedia element can be connected to a synchronous controller for data access control. Reference numeral 40 in the fifth figure is an interrupt controller, and reference numeral 50 is a synchronous controller. When the multimedia data source 5 2 2 generates multimedia data, the synchronization controller 50 will first determine the type of the multimedia data (step 50 2); after that, determine whether the multimedia data source has been written into the winter cache memory (step 5). 0 4); then judge whether the multimedia data can be read into the corresponding data target area, and the data target area can be a liquid crystal display or a communication port; and then, when the multimedia data has been read into the corresponding data target Zone time (step · step 508), in steps 512 and 514, the synchronization status change and abnormal synchronization status of the multimedia device will be judged, and it will be processed in the interrupt mask 5 1 6 in the interrupt controller 40_ . After the interrupt controller 40 receives such an interrupt request, or the interrupt request from the external low-speed input / round-out device 52 0 and DSP 41 4, it will determine the priority of each signal in step 5 1 8 and then pass the CPU 41 0 For processing. In the synchronization controller 50, if there is no synchronization state change or abnormality, it can be written into the data target area (step 5 1 0), and then return to step 50 2 to determine the next multimedia data.

Description of the invention () Furthermore, in the multimedia domain 30, DSP414 is the core of processing. At this time, it not only acts as a processor in the multimedia field, but also can control all the pieces to ensure the synchronization and the smooth transmission of data (such as the synchronization control described in the fifth figure). The role of an independent synchronous control module 'DSP414 can give full play to its ability to process multimedia data and improve its processing performance. Faced with the fierce competition of multimedia, manufacturers must consider the DSP system design repeatedly in order to exert the best performance. Some Wei families even embed DSP in the chip as the heart of the processing engine (and quickly develop tools and support libraries, etc.), and externally integrate the hardware required by specific users such as converters, flash memory, and Other functional components are integrated into a single chip. This DSP-based chip integration design not only optimizes the system's power consumption, cost, and size, but also retains all the functions and performance of the original design. Referring to the sixth figure, this figure is a block diagram of the DSP hardware of a handheld computer according to the present invention. When the multimedia data is stored in the synchronous dynamic random access memory 602, the DSP uses the instruction temporary storage area 604 and the data temporary storage area 606 in the temporary storage controller 60 to perform instruction and data access control. The reference number 70 is the core processing engine of the DSP, which uses the pointing unit 608 to obtain the multimedia instructions from the instruction temporary storage area 604, and then decodes the multimedia instructions through the jiema unit 6 10, and sends the multimedia instructions to the execution unit 80. Processing: In the execution unit 80, it also includes a multimedia instruction processing unit 612, a floating point arithmetic unit 6 1 4, a stream instruction processing unit 61 g (that is, a bit stream instruction and its acceleration instruction), and an arithmetic logic. Unit 618 and so on. After the execution unit 80 calculates the result, the result of the Ji address type will be transmitted to the access control unit.
