-mcpu=cortex-m4 -mthumb The choice between the two depends also on what one wants to do. What kind of interfaces are needed and how many, like SPI, UART, CAN, ADC, DAC, etc. Also how fast does it need to be. The STM32F411 can clock up to 100MHz, where the ATSAMD21G18 c...
between the execution phase (CPU clk) and write phase( Bus clock)... N.B: This was not a problem in HC08 micros because bus= cpu clk , but in HCS08 bus clk=1/2( cpu clk) There surely will be bottleneck condition...ultimately bus clk dictates the entire speed of t...
I am learning Processor Expert and plan to use it in my kinetis project. I noticed there two kinds of components(LDD and CPU internal). CPU internal component looks to be a more straight way. What's the advantage of LDD components? Could you give me a example in...
What is the difference between x86 and x64? As you guys can already tell, the obvious difference will be the amount of bit of each operating system. x86 refers to a 32-bit CPU and operating system while x64 refers to a 64-bit CPU and operating system. Does having more amount of bits...

Packages can be discrete components (memory, CPU, other logic) or a System-in-a-Package stacked with another package for added or expanded functionality. PoP provides more component density, and also simplifies PCB design. It also can improve signal propagation since the interconnects between ...
"This value was out-of-range. Please use a level between -50 and +12" = "此值范围的。请使用-50和+12之间的水平 " "Analysing edit" = "分析剪辑" "Master Levels" = "主电平" "Master volume level" = "主音量电平" "Reset the volume to 0 dB" = "音量复位为0 dB" ...
The processor emphasizes more on functions, and refers to the unit that performs processing, which can be said to be MCU, CPU, etc. The scope of integrated circuits is much wider. Even if some resistors, capacitors and diodes are integrated together, it may be an analog signal conversion ch...
