Difference between microcontroller and microprocessor. Microprocessor = cpu; Microcontroller = cpu + peripherals + memory Peripherals = ports + clock + timers + uarts + adc converters +lcd drivers + dac + other stuff; Memory = eeprom + sram + eprom + flash. In Microprocessor more op-codes, few bit handling instructions.
The microcontroller is typically preprogrammed with a "bootloader" program that allows a program (called a "sketch") to be loaded into the microcontroller over a TTY serial connection (or virtual serial over USB connection) from a PC. Microprocessor. A microprocessor is an IC that contains only a central processing unit (CPU).
In general a microcontroller is taken as being an embedded device which is internally programmed to perform a specific task. There is minimal user interaction and little or no flexibility. A microcontroller is typically fairly low powered with only small amounts of memory and ROM (flash). Conversely a System-on-Chip is the other end of the ...
FPGA vs microcontroller: not optimised for sequential code processing, but can do truly parallel tasks very easily as well. Generally FPGAs are programmed in HDL, microcontrollers in C/Assembly Whenever speed of parallel tasks is an issue, take an FPGA, evolve your design and finally make it an ASIC if it's cheaper to you in the long run (mass ...
A microcontroller is just a single chip. An ECU consists at least of: a metal enclosure; printed circuit board; microcontroller(s) or microprocessor(s) power supply; protection components; These are two different things. Just like CPU != laptop. This is what an ECU looks like (and the biggest chip is likely the MCU or MPU):
Doing an FFT in a standard microcontroller will take a long time compared to performing it on a MAC of the DSP. Processing I2C and serial signals is not the same as processing waveforms in a DSP. Totally different kind of processing going on since serial signals are just bit-banging. Here's a similar discussion on a DSP forum: DSP vs ...
To me, the definition is that a microcontroller is a chip with microprocessor, memories and peripherals integrated. \$\endgroup\$ – Justme Commented Jun 22, 2021 at 10:21
That is what we call a microprocessor (uP). From there the development forks: the CPU-on-a-chip is made more powerfull (faster, parallel execution, fast execution of complex instructions like divide and transcendentals), a cache is added, more CPU's are combined in one chip, etc.
A typical meaning for a microcontroller is that it is a microprocessor and a bunch of memory and peripherals in same package. And thus a microprocessor has usually no built in memory, just registers. And many microprocessors can have more registers than many microcontrollers do, so it depends on the architecture.
As far as you question, no, noone would ever consider the Raspberry Pi a microcontroller, simply because it is intended for a larger scale than most microcontrollers are marketed for. See microcontroller vs. System on chip for more info as well.
