1. What are some of the first things we need to know when getting an unfamiliar processor to develop a product?

1). which company does this processor belong to? What processor series does this company have?

2). What is the development platform? Version history and some links to the development platform? The latest version?

3). is it based on library development or register operations? The version of the library?

4). the number of bits of the processor? The kernel of the processor? Internal memory structure? How often does the processor work?

5). What peripherals do the processors have? How do I download programs? Can I simulate online? Simulation interface?

6). processor instruction set?

7). reference books, development boards, routines?

2.tms320c28x_tm is a low-power 32 bit fixed-point processor core with reduced instruction set functionality risc tms320c2802x tms320c2803x piccolo series belongs to this kernel, is DSC (digital signal processor) class. Single-cycle execution once 32*32 or two times The multiplication of span style= "Font-family:times New Roman" >16*16 EPWM with precision up to 150ns

3. Where does the system clock come from? Internal oscillator or external oscillator. Is it possible to configure an internal oscillator or an external oscillator with the relevant registers? There is also a register of the multiplexed configuration of the pins connected to the external oscillator, that is, whether the pin is used for GPIO, function io, or crystal IO configuration? How many internal crystal oscillator? If there is more than one, it involves the question of which one to open? What is the internal crystal oscillator? How to open it? How to Octave? Can internal crystals work for those peripherals? Or just work for the kernel?

4. Where does the peripheral clock come from? It may be the system clock or the crossover. Will the clock going into the peripheral be processed? If a peripheral clock is not used, no need to open it.

5. When operating a peripheral register, the real execution from the CPU Write to the peripheral is a delay of the system clock, which is the smallest real-time response time of the peripheral. Some of the peripheral registers in this processor also have a concept that is protected by the CPU , which must first be protected, written, and protected.
