They handle the computation of graphics in various applications. Similar to the CPU, the GPU consists of processing units called cores. GPU can also perform computation in applications traditionally handled by the CPU. In mobile devices GPU is usually utilized by games, UI, video playback, etc. GPU is a graphical processing unit, which handles computation for 2D/3D graphics applications. It is measured in Megahertz (MHz) or Gigahertz (GHz). The frequency of the processor describes its clock rate in cycles per second. They increase the performance of the device allowing the execution of multiple instructions in parallel. Presently, besides single-core processors, there are dual-core, quad-core, hexa-core and so on multi-core processors.
BLU R1 HD BATTERY CHARGING INSTRUCTIONS SOFTWARE
If the CPU does not find the data needed in L2, it proceeds to look for them in the 元 cache memory (if there is such) or in the RAM.Ī CPU core is the processor unit, which executes software instructions. Just like L1, it is much faster than the system memory (RAM). The L2 (level 2) cache memory is slower than L1, but has a larger capacity, instead, which allows it to cache more data. In some processors the search in L1 and L2 is simultaneous. If the processor does not find the data needed in L1, it continues to look for it in the L2 cache memory. The L1 (level 1) cache memory has a small volume, but operates faster than the RAM and the rest cache memory levels. The cache memory is used by the processor in order to shorten the time needed to access data and instructions that a frequently used. Information about the set of instructions the processor can execute. The instruction set architecture (ISA) is a set of commands used by the software to manage the CPU's work. 64-bit CPUs provide better performance than 32-bit ones, which on their part perform better than 16-bit processors. The CPU bits are determined by the bit-size of the processor registers, address buses and data buses. Its main function is to interpret and execute instructions contained in software applications. The value in nanometers represents half the distance between elements that make up the CPU.ĬPU is the Central Processing Unit or the processor of a mobile device. Information about the process technology used in manufacturing the chip. The SoC integrates different hardware components such as the CPU, GPU, memory, peripherals, interfaces, etc., as well as software for their functioning. System on Chip (SoC) A system on a chip (SoC) includes into a single chip some of the main hardware components of the mobile device. A further development of the technology is called LTE Advanced. It has been developed by the 3GPP based on the GSM/EDGE and UMTS/HSPA technologies in order to increase the speed and capacity of wireless data networks. LTE is deemed to be the fourth generation (4G) of mobile communications technology. It has been developed by the 3GPP and its major advantage is the provision of greater bandwidth and spectral efficiency, due to the W-CDMA technology. Based on the GSM standard, it is deemed as a 3G mobile network standard. UMTS stands for Universal Mobile Telecommunications System. It has been improved with the addition of General Packet Radio Services (GPRS) and later via the Enhanced Data rates for GSM Evolution (EDGE) technology. GSM (Global System for Mobile Communications) was developed to replace the analog cellular network (1G), therefore it is referred to as a 2G mobile network. Networks A mobile (cellular) network is a radio system, which allows a large number of mobile devices to communicate with each other. Materials used in the fabrication of the device's body.
