Info

From the desktop… • Desktop Intel based platform is around for a very long time • A lot of skills, tools and techniques developed for it • 2 major flavors – x86 and x64 with some extensions(MMX, SSE, AVS…) • Hardware is abstracted by OS and drivers 6 RECON 2017 Brussels
…To Embedded • Usually around some micro CPU • There are a lot of choices(PIC, AVR, Intel, MIPS, ESP…) • Very common cores are ARM Cortex M0, M3 and M4 based • Those devices comes with a lot of peripherals to support virtually any need • Need to develop both hardware and software side 7 RECON 2017 Brussels
