Working Principle of the RM44L920APZT

The RM44L920APZT works on the principle of a super-heterodyne architecture, which combines multiple functions into an integrated controller. The architecture of the microcontroller consists of four main functional subsystems: address decoding, instruction decoding, peripheral control and address map.

The instruction decoding subsystem is responsible for decoding the instructions given by the microcode instruction set. The address decoding subsystem maps the memory address by decoding the physical address and mapping it to a corresponding logical address. The peripheral control subsystem responds to the data outputs of the instruction and address decoding subsystems to perform the appropriate operation with the peripheral. The address map subsystem stores the configuration information in the program memory, which is then mapped into the microcontroller’s internal address space.

The RM44L920APZT also includes an integrated high-speed multiplier/accumulator, which executes arithmetic and logical operations at a higher speed than the normal instruction execution. This feature enables applications that require intensive computation operations such as signal processing, image/video processing and 3D graphics.
