DDR is just an acronym for Double Data Rate. Compared to single data rate (SDR) SDRAM, the DDR SDRAM interface makes higher transfer rates possible by more strict control of the timing of the electrical data and clock signals. Implementations often have to use schemes such as phase-locked loop...

Yes, A processor is a generic term used to describe any sort of CPU, regardless of cores. Same goes for CPU, it does not imply single or multi-core and can be used to refer to either. A central processing unit (CPU) is the electronic circuitry within a computer that carries out the instructio...
