Parallel processing, in which applications are partitioned into multiple tasks that are executed concurrently by multiple processors is used for high-throughput needs where even the single fastest computer cannot be good enough.
Multiple processor system architectures differ widely in … Read More
LCD crystal displays allow a better user interface compared with LED displays as it is much easier to display text messages in LCD displays. They also consume much less power than LED displays. Nonetheless, LED displays have better intensity than … Read More
A computer system uses memory elements for storing program instructions, data, and other information. From the perspective of the instruction set, a memory is an array of words, each identified by a unique address that indicates its location within the … Read More
Microprocessors perform various basic operations that include data transfer instructions, arithmetic instructions, logic instructions, control transfer instructions and machine control operations. This set of commands (instructions set) used to control the functions of a microprocessor is specific to a given … Read More
In this article, we briefly describe how to interface LEDs and electromechanical relays to microcontrollers. Note, a detailed description on how this is done can be found in the official documentation of the microcontroller you are working with. Here, we … Read More
The 8085 Microprocessor is one of the most popular microprocessors. In this article we look at some of the basic features and pin-out configuration of this microprocessor.
The block diagram of the 8085 microprocessor is shown below:
Once the program is written and translated into executable code, the resulting HEX file is loaded to the target microcontroller’s program memory with the aid of a device programmer. The type of device programmer depends on the type microcontroller to … Read More
There are two basic primary architectures used for mapping special function registers into memory space. In the first type of arrangement, I/O space and memory space are separated as illustrated in Figure 1.0. The I/O devices have a separate address … Read More
The microprocessor is the heart of a microcomputer system and can be described as a programmable device that accepts binary data from an input device; then processes the data according to the instructions stored in the memory and provides results … Read More
