ARCEM处理器嵌入式系统开发与编程.html

序 In recent years processor IP has become ubiquitous as mobile and consumer device makers have migrated their designs from using stand-alone processor chips to processor cores integrated into more power-efficient System-on-Chips（SoCs）.At the same time,software functionality and complexity has increased at a dramatic rate,requiring additional processing bandwidth.Many of today’s processors,including the ARC EM Family of processor IP cores,are focused on delivering increasing levels of performance with lower power consumption and a minimum silicon footprint. ARC EM processors were first introduced in 2012.Designed for ultra-low power operation,EM cores hit a sweet spot in processing efficiency and have since become Synopsys’most successful processor product line.EM processors are now used in a wide variety of embedded applications,especially where exceptional performance-to-power（DMIPS/mW）or performance-to-area（DMIPS/mm2）ratios are needed such as the Internet of Things（IoT）. The ARC EM family utilizes a scalable 16-/32-bit RISC instruction set architecture（ISA）that is optimized for the unique requirements of embedded and deeply embedd......
