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
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 : Data Bus, Control Bus and Address Bus. An 8-bit processor will be using 8-bit wide bus. ...
Clock speed.One approach was to make the processor's clock faster. The clock is the "drumbeat" used to synchronize the processing of instructions and data through the processing engine.Clock speedshave accelerated from several megahertz to several gigahertz (GHz) today. However, transistors use up...
MISO (Master In Slave Out): In a SPI (Serial Peripheral Interface), multiple peripheral devices (Slave) are being communicated with the microcontroller (Master) quickly. So MISO is used to send the data to the master (microcontroller) from the salve (peripheral device). MOSI (Master Out Slav...
A keypad is one of the most commonly used input devices in microprocessor applications. In a standard keypad wired as an X-Y switch matrix, normally-open switches

aA SoC consists of both the hardware described above, and the software that controls the microcontroller, microprocessor or DSP cores, peripherals and interfaces. The design flow for an SoC aims to develop this hardware and software in parallel. SoC包括硬件被描述的上面和控制微型控制器、微处理器...
2 In PowerPC Microprocessor Family: The Programming Environments Manual for 64-bit Microprocessors pp423 When the RESERVE bit is set, the processor enables hardware snooping for the block of memory addressed by the RESERVE address. /***/ If the processor detects that another proces...
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...
Microprocessor-based protective relays can detect small changes in parameters like voltage, current, resistance, or temperature that can be used to identify the early stages of a problem before it is severe enough to trip conventional protective devices like circuit breakers or fuses. A protection ...
