In contrast to a computermicroprocessor, a microcontroller is intended for some specific tasks. So the hardware requirements like RAM, ROM and other peripherals are very less. Thus everything is embedded into a single chip, by reducing the overall size very much. Low Cost Microcontrollers are ver...
There are numerous peripherals in a single microprocessor chip LX6 or LX7 by Tensilica Xtensa. This is a very advanced kind of microcontroller chip with so many peripherals. They include UARTs, SPIs, timers, touch sensors, SPIs, Counters, I2S and I2C Interfaces, Pulse Width Modulators, digital-...
Common Terms used in a Microprocessor Here are some common terms that we will use in microprocessor field. Bus A bus is a set of conductors intended to transmit data, address or control information to different elements in a microprocessor. Usually a microprocessor will have 3 types of buses :...
Multicore processors have multiple processing units incorporated in them. They connect directly with their internal cache, as well as with the system bus and memory. However, multicore chips have several issues to consider. First, the addition of more processor cores doesn't automatically improve c...
This 4x4 matrix keypad has 16built-in pushbutton contacts connected to row and column lines. A microcontroller can scan these lines for a button-pressed state. In the keypad library, the Propeller sets all the column lines to input, and all the row lines to input. Then, it picks a row...
has a transceiver in it. When the signal comes back from the tag through the antenna of RFID reader it is fed to the demodulator and then decoded by a decoder where the original data can be obtained and then further processed by amicrocontrolleror a microprocessor to perform a specific task...

electromechanical designs have mostly been replaced by solid-state devices. But electromechanical relays continue to be used in high-power applications in electricity transmission and distribution systems. Microprocessor-based protective relays can detect small changes in parameters like voltage, current, resi...
If you worked with a microcontroller, you were given (from the vendor) a specification, a design sheet, a manual of all its registers and nothing more. Translation:you had to write your own operating system (kernel included) from scratch.Although this guide assumes the standard generic 32-bit...
