Low-power-consumption wearable equipment system

Abstract

The invention provides a low-power-consumption wearable equipment system. Based on a memory formed by a register, a local nonvolatile memory, a main memory and an external high-capacity nonvolatile memory together, a processor of a multi-microcontroller-core structure and a new multi-core management mode are adopted, so that the low-power-consumption wearable equipment system is in an ultra-low-power-consumption state for a long time and is started immediately once awakened, while system performance is improved, the size and consumption of a battery are reduced, achieving cost of the system is reduced, equipment is more microminiaturized, then portability of the wearable equipment is greatly enhanced, and moreover requirements of different users can be met according to usage habits of the different users.

Description

technical field [0001] The invention relates to the field of wearable technology, in particular to a low-power wearable device system. Background technique [0002] With the rapid development of semiconductor devices, semiconductor devices follow Moore's law, and the number of transistors per unit area doubles every eighteen months, which makes semiconductor devices more and more integrated, while the volume is getting smaller and smaller; for example, from The original mainframe computer invented by IBM, and then the personal computer (personal computer), which was reduced in size by about 10 times, and then the notebook computer (laptop), whose size was reduced by about 10 times, and the current mobile devices ( cellphone, tablet), and its volume has been reduced by about 10 times. [0003] As the size of electronic products continues to shrink by an order of magnitude, although the ability of some electronic products to process information is decreasing, the information ...

Problems solved by technology

[0010] Figure 4 is a schematic diagram of the memory structure in a traditional wearable device; such as Figure 4 As shown, in the traditional memory structure, there are registers and on-chip caches on the chip (consisting of multiple on-chip caches such as the first level L1 and the second level L2), and there are main memory and large-capacity non-volatile memory off-chip. Memory; if the above-mentioned memories are integrated on the wearable device, it will occupy a large amount of on-chip area and off-chip resources, which will affect the wearability of the device and reduce the portability of the product
