Using the Microcontroller Timers
Timing is an essential function for generating signals with precisely determined duration, or for counting external events. For this reason, a timer subsystem is present in all microcontroller implementations. More ...
Capacitors in DC Circuits
A capacitor is a component that can be used to store an electrical charge. A capacitor can be used to create a timer. This time delay can be used to smooth a changing current flow in a circuit, or it can be used to absorb spikes and prevent false triggering of other components. More ...
Network on a Chip (NoC)
NoC (Network on a Chip) is a method of placing a much larger number of processors on a multi-core chip. Much like a regular network, NoC has multiple point-to-point data links that are interconnected by routing switches. More ...
Digital Logic Levels and Transfer Characteristics
A digital system uses discrete logic levels, 0 and 1, while the real world is a continuous range such as a voltage from 0 to 5. To make design easier, engineers view the system in the abstract. More ...
Arduino Microcontroller Development Platform
The benefit of the open source Arduino Microcontroller Development Platform is that the software is free and the hardware is cheap. This makes it one of the cheapest platforms on which to develop prototypes. More ...
Operating System Services
An operating system provides an environment for the execution of programs. It provides certain services to programs and to the users of those programs. These operating system services are provided for the convenience of the programmer, to make the programming task easier. More ...
Microcontroller Registers
Registers are special small memory locations where the microcontroller can write data to or read data from. Special function registers help point to main memory locations, indicate the result of a mathematical operation, hold parts of an instruction or indicate the status of some operation or hardware feature. Some registers are general purpose and may be used by the programmer at their own discretion. More ...
CPU Process Memory Address Binding
For a program to run on a CPU it must be brought from files in long-term, non-volatile storage to main memory. Addresses in the source program must be mapped to addresses in main memory. More ...
How Computer Memory Works
Every program being executed and every piece of data being manipulated must be copied from a storage device, such as a magnetic disk, into main memory. It's important to understand the basic types of memory. More ...
Operating System Memory Management
Computers must keep several programs in memory, creating a need for memory management. Many different memory-management schemes are used. The operating system Keeps track of which parts of memory are currently being used, and moves data into out of memory, and allocates and deallocates memory as required. More ...
The Many Processes of Silicon Wafer Manufacturing
A silicon wafer is a thin, circular disc used in the manufacture of integrated circuits and semiconductors. The silicon wafer manufacturing process is interesting. More ...
Multiuser Operating System Functions
Some operating system functions like resource allocation, accounting, protection and security exist not for helping the user, but rather for ensuring the efficient operation of the system itself. More ...
