This paper introduces the current situation and development of ARM company and ARM chip, introduces the selection method of ARM chip from the perspective of application, and introduces the ARM chip with multi-core structure. The main ARM chip suppliers, their products and application areas are listed.
Very popular ARM cores are ARM7TDMI, StrongARM, ARM720T, ARM9TDMI, ARM922T, ARM940T, RM946T, ARM966T, ARM10TDM1 and so on. Since V5,ARM has provided Piccolo DSP cores to Chip designers for the design of ARM DSP SOC (System On Chip) architecture chips.
In addition,ARM chips have also been supported by many real-time Operating System vendors, the more well-known are: Windows CE, Linux, pSOS, VxWorks Mucleus, EPOC, uCOS, BeOS and so on.
With the development of embedded applications in China,ARM chips will inevitably gain extensive attention and application. However, because the ARM chip has as many as a dozen kinds of core structure, more than 70 chip manufacturers, and a kaleidoscope of internal functional configuration combinations, it brings certain difficulties to developers when choosing solutions.
