The DesignWare® ARC® EM4 and EM6 processors are optimized for use in embedded and deeply embedded applications where high performance with minimum power consumption is essential. The cores offer outstanding performance density, delivering 1.81 DMIPS/MHz and 4.02 CoreMark/MHz within a very small footprint and extremely low power consumption.
The ARC EM4 and EM6 processors are based on the ARCv2 instruction set architecture (ISA) and pipeline, which provides leadership power efficiency and code density.
Both the ARC EM4 and EM6 support up to 2MB of closely coupled memory and are ideal for embedded applications in consumer, IoT, networking, automotive and other power- and cost-sensitive applications. The ARC EM6 processor also supports up to 32KB of instruction and data cache.
A low-cost ARC EM Starter Kit enables designers to start early development of their designs. The EM Starter Kit, consisting of a hardware platform that includes pre-installed FPGA images with peripherals and a software package, is a versatile platform for rapid software development, code porting, software debugging, and system analysis.
