dominated by 32-bit CPU cores. The CPU cores designed by arm are commonly known as "ARM chips ", however, strictly speaking, an ARM chip should be a single-chip microcomputer designed with the CPU core of the arm. An SoC chip made with the CPU core of the arm is generally not called an ARM chip.Therefore, the ARM chip mentioned by the landlord is an advanced general-purpose microcontroller.DSP = digital signal processing, that is, digital signal processing. Like "Arm chip", "

ARM microprocessor instruction set Overview
The arm instruction set is load/storage-type. That is to say, the instruction set can only process the data in the register, and the processing results must be put back into the register, access to the system memory requires special loading/storage commands. ARM microprocessor instruction sets can be divided into six categories
