Operation and structure of RS232 Programming Cable
Leaving loose and extensible general route structure.
In the traditional system structure, the pipeline is generally used, which is characterized in that each functional unit is connected by a circuit. If the function of a certain part is to be added, deleted or modified, the corresponding functional module must be adjusted. Therefore, this structure Not open. In order to realize the interconnection of various functional units in the RS232 Programming Cable system, an open and expandable hardware platform is formed, and at the same time, it has a high data throughput rate. The software RS232 Programming Cable system must adopt a new interconnection structure, which is characterized by relatively simple implementation and can directly apply a variety of bus standards (such as VME, bus, PCI bus, etc.). Unique interconnection structure based on RS232 Programming Cable bus.
High-speed parallel DSP part.
In the digital processing operation of the RS232 Programming Cable system, the most difficult are up-conversion, filtering and sub-sampling. The high-speed parallel DSP includes digital baseband processing, modulation and demodulation, bit stream processing and decoding functions. For RS232 Programming Cable FM and spread spectrum systems, this part should also have despreading and dehopping functions. To achieve this part of the function, it is necessary to use high-speed parallel DSP to form a multi-processor parallel computing system, including more multiple access calls, wider RS232 Programming Cable program bus and data bus, single instruction multiple data, multiple Instruction multiple data structure and the use of super-instruction structure, etc., this part can be realized by the dedicated digital integrated circuit chip ASIC.
Through the above introduction and analysis of RS232 Programming Cable, hope it helps you.
