To understand the microcontroller, we need to go back to a simpler system. The basic microprocessor system needs a certain set of chips, with suitable interconnections, as follows: • CPU • RAM • ROM • I/O ports. These devices must be interconnected by: • Address bus • Data...
A typical programmable machine can be represented by five components; microprocessor, memory, input, output, and bus. These five components work collaboratively and interactively with each other to perform a given task; thus they comprise a system. The physical components are called hardware. A set...
Coprocessors, such as floating-point units (FPUs), are designed to provide auxiliary support for a system’s main CPU to boost performance during certain demanding tasks, such as carrying out advanced scientific calculations or complicated mathematical formulas. ...
