Showing Results For: Embedded - DSP (Digital Signal Processors)
In contrast to microprocessors or microcontrollers, similar devices, digital signal processors have internal architectures tailored for the continuous execution of algorithms dominated by multiplication and addition operations performed on a continuous stream of data. This sets them apart from algorithms that are dominated by conditional logic or a multitude of concurrent processes. They are frequently employed in programs like audio and video signal processing. Moreover, DSPs are mainly designed for arithmetic operations, i.e., addition, subtraction, multiplication, and division. They take worldly signals such as audio, videos, voice, pressure, temperature, and point, digitized and arithmetically manipulated, and then present them in digital form.
They are frequently used in consumer electronics like mobile phones, disc drives, and high-definition television (HDTV) products, as well as in areas including audio signal processing, telecommunications, digital image processing, radar, sonar, and voice recognition systems.
A visual representation are the advantages of DSPs. Because it considerably raises the overall value of hearing protection, digital signal processing is crucial. DSP lowers noise without obstructing the speech signal, in contrast to passive protection.
These microprocessors are provided in two major types, which are discussed below:
GPRs are employed as an internal storage mechanism, and the fixed-point processor uses non-privileged instructions. The Power PC fixed-point processor uses the following registers for non-privileged instructions. 32 General-Purpose Registers of 32 bits (GPRs). Furthermore, a fixed point DSP is mainly designed to present and control integers and negative or positive whole numbers in a context.
High-performance floating-point operation execution is offered by the floating-point processor. There are instructions for performing math, comparison, and other operations in floating-point registers and transferring floating-point data between storage and the registers.
