Brief introduction of chip, memory and its key indicators I

LPDDR5 (Low Power Double Data Rate SDRAM) Low power double data rate memory , Performance is better than the previous generation 50%, Power consumption is reduced to 20%.
 

eMMC（embedded Multi Media Card）, Embedded multimedia card , Is a flash card standard .

UFS（Universal Flash Storage） A high-speed memory device ,UFS The transmission speed of has been far ahead of eMMC.

NOR Flash, Also known as code falsh, NOR falsh By Intel company-developed , It's a random access device , With dedicated address and data line （ and SRAM similar ）, Read and write in bytes , Allow access to any location in memory ,（NOR Mainly used in code storage media ）

Sec NOR Flash, Integrated data security and function security memory solutions NOR Flash. Semper Secure NOR Flash memory

Orin-X, NV Self driving chip launched , Have 12 cores, 254TOPS

TOPS, TOPS yes Tera Operations Per Second Abbreviation ,1TOPS Represents that the processor can perform one trillion times per second （10^12） operation

S32G, NXP The vehicle network processor launched by the company , Provide complete ASIL D function , Including lock step Arm Cortex-M7 Microcontroller core , And lock step Arm Cortex-A53 High performance kernel Group .

MCU, Micro controller , Integrated flash,ram And some peripheral devices . It's fast to start , Do not have MMU, Can not run Linux System , Only small operating systems can be run . More real time , Lower power consumption .

MPU, Microprocessor , The designer needs to build it by himself flash and ram, The dominant frequency is relatively high , It is suitable for scenes with complex operations .

            for example i.MX6 and i.MX8 series

SA8295P, Gao TONGDI 4 Dai Xiaolong digital cockpit platform , Positioning is the central processing center in the evolution of the architecture under the regional system , That is, the central processing unit under the central integrated architecture . use 5nm process , In performance 、 multimedia 、 Safety technical facilities 、 Compared with the previous generation, audio and video processing capacity has been greatly improved , It is invincible in the cockpit .
