Single-chip
SCM is also known as micro-controller (Micro-controller Unit), commonly used letters of the acronym MCU that it was first used in industrial control.
Only a single chip by the CPU chip developed from a dedicated processor. The first design is by a large number of peripherals and CPU on a chip in puter system, smaller, more easily integrated into plex and demanding on the volume control device which. INTEL'sZ80 is the first designed in accordance with this idea processor, then on the development of microcontroller and dedicated processors have parted ways.
Micro-controller early are 8-bit or 4 bits. One of the most essful is the INTEL 8031, for a simple, reliable and good performance was a lot of praise. Then developed in 8031 out of MCS51 MCU Systems. SCM systems based on this system until now is still widely used. With the increased requirements of industrial control field, began a 16-bit micro-controller, because the cost is not satisfactory but have not been very widely used. After 90 years with the great development of consumer electronics, micro-controller technology has been a huge increase. With INTEL i960 series, especially the later series of widely used ARM, 32-bit micro-controller quickly replace high-end 16-bit MCU status and enter the mainstream market. The traditional 8-bit micro-controller performance have been the rapid increase capacity pared to 80 the number of times. Currently, high-end 32-bit micro-controller clocked over 300MHz, the performance catching the mid-90's dedicated processor, while the average model prices fall to one . dollars, the most high-end [1] model only 10 SCM systems are no longer only in the development and use of bare metal environment, a large number of proprietary embedded operating system is widely used in the full range of SCM.
