devices that use microprocessor or microcontroller chip (MCU), peripheral circuits, and internal programs to implement specific functions. For example, 8-bit single-chip microcomputer, 32 ARM, and DSP chip all belong to the category of embedded core chip. The 8-bit MCU market has gradually stabilized, and 32-bit MPU represents the development direction of embedded technology and is accelerating development

-core CPU. In fact, it only integrates the general-purpose processor with the GSM module. Generally speaking, it is a combination of ARM + DSP, while Intel'sThe CPU needs to be separately used with separate communication modules. Therefore, the power consumption of the two chips will definitely be greater than that of a single chip. Of course, the price is also a very important factor, although TI's CPU needsIt is more expensive than Intel's CPU, But

requirements will not change, otherwise, at least reserve enough spare Rom space for possible changes.In most cases, we can try to write some program code in the Rom to observe the space occupied by the Code. For a microprocessor system with an internal ROM, system programs can only occupy limited program memory space. D. Experience: Rom is similar to RAM usage, and the program code length is related to the selected development language. For example,

-based data tables. The hard part of the RoM space capacity required for prediction is the length of the prediction program code. The solution to this problem can only improve the prediction accuracy with the gradual accumulation of experience.However, the most important thing is not to accurately calculate the code length of a program, but to clearly estimate the upper limit of the code length. According to experience, if 80% of the RoM space is occupied by code, it will be too crowded unless i
