Problems solved by technology

The embarrassment of the prior art is that the general (external) clock pulse generator 26 is difficult to simulate these dynamic operating conditions, and it is impossible to simulate many real situations, let alone the combination of slow memory and high-speed microprocessor. Possibility of cooperating with processor system 20

Embodiment Construction

[0027] see image 3 , image 3 It is a schematic diagram of an embodiment of the present invention. image 3 The architecture includes: a buffer control device 38, a microprocessor (Micro-processor) 30, and a memory 32, and the memory 32 stores a plurality of digital data. and figure 1 Comparing the existing embodiments, it can be seen that the basic structure of the present invention still utilizes the microprocessor 30 to access the memory 32, but in the process of accessing, since the memory 32 of the present invention is expected to use a slow memory (such as a serial memory) flash memory) is completed, and in the situation that the microprocessor 30 is still running at high speed, in order to avoid data loss or blocking during transmission, we allow the microprocessor 30 to indirectly access through the buffer control device 38 in this embodiment The memory 32 is combined with the technical features of the method disclosed in the present invention to ensure that the mi...

Abstract

This invention provides a kind of dynamic adjustment method of Operating Clock of Microprocessor Emulator. The Microprocessor Emulator is electrically connected with a Microprocessor System, which comprises a buffer control apparatus. The method comprises: (a) the Microprocessor Emulator sends an Access Address to the buffer control apparatus; (b) if the access address is in the buffer control apparatus, the buffer control apparatus outputs the Operating Clock to the Microprocessor Emulator to operate the Microprocessor Emulator; (c) if the access address is not in the buffer control apparatus, the buffer control apparatus stop outputting the Operating Clock to the Microprocessor Emulator to pause the Microprocessor Emulator.

Description

technical field [0001] The invention provides a method for dynamically adjusting the operating clock of a microprocessor emulator (Microprocessor Emulator), especially a method for electrically connecting the microprocessor emulator to a buffer control device to dynamically adjust The operating clock pulse of the microprocessor simulation device is used to simulate a method for a microprocessor to access at least one memory. Background technique [0002] With the evolution of the digital age, in order to meet the surge in user needs, the speed and accuracy of digital data extraction, transmission, storage, use, and display must be continuously enhanced, and the performance of the information system is most closely related , that is, the access operation of the processor and the associated memory. In the prior art, when a microprocessor (Micro-processor) requests data (program code) to a program memory, that is, when the microprocessor wants to access the program memory, it ...
