What is the role of a DSP? What does DSP mean?

DSP (Demand-SidePlatform) is a demand-side platform with precision marketing as the core concept. This concept originated in Europe and the United States, where online advertising is developed, and is a new field of online advertising that has emerged with the rapid development of the Internet and the advertising industry.

DSP Definition: A demand-side platform allows advertisers and agencies to make it easier to access, as well as more efficient in buying ad inventory, as the platform brings together inventory from various ad exchanges, ad networks, first-party platforms, and even more. With this platform, there is no need for another cumbersome purchase step – a purchase request.

DSP is an abbreviation for Digital Processor, which is a logic device used to do digital signal processing. It is unique in that it can process data instantly. The interior of the DSP chip adopts a Harvard structure that separates the program and data, and has a special hardware multiplier, which can be used to quickly implement various digital signal processing algorithms.

In today's digital era, DSP has become a basic device in the fields of communications, computers, and consumer electronics.

Conversion formula: c(Celsius)=(f(Fahrenheit)-32) c=(375-32) =343 Result keeps two decimal places) 375 degrees Fahrenheit is approximately Celsius.

DSP refers to the use of computers or special processing equipment to collect, transform, filter, evaluate, enhance, compress, identify and other processing of signals in digital form to obtain a signal form that meets people's needs (embedded microprocessor). With the rapid development of computer and information technology, DSP technology came into being and has developed rapidly.

Digital signal processing and analog signal processing are a subset of signal processing, the category belongs to signal processing, the so-called signal processing, is to process the signal recorded on a certain **, in order to extract useful information process, it is the signal extraction, transformation, analysis, synthesis and other processing processes are collectively named. However, digital signal processing and analog signal processing do not handle the same objects, so the specific process of processing is also different, but the purpose is to extract useful information.

Digital Signal Processing (DSP) is an emerging discipline that involves many disciplines and is widely used in many fields.

Since the 60s of the 20th century, with the rapid development of computer and information technology, digital signal processing technology has come into being and has developed rapidly. Over the past 20 years, digital signal processing has been widely used in DSP technology in the field of communications.

Digital signal processing is the use of computers or special processing equipment to collect, transform, filter, estimate, enhance, compress, identify and other processing of signals in digital form to obtain a signal form that meets people's needs.

The X0D X0A advertising module includes the following main functions: time targeting, regional targeting, crowd targeting, content targeting, retargeting, combined frequency control, and creative intelligent switching. In addition, it has a comprehensive resource management system and advertising monitoring and analysis system.

The X0D X0A advertising monitoring and analysis system includes: data monitoring part and multi-dimensional directional data analysis for real-time optimization of advertising.

DSP refers to the advertising demand-side platform, with precision marketing as its core concept, which is an emerging online advertising concept, followed by digital signal processing.

DSP has a wide range of applications in signal processing, communication, radar and other fields, and what we usually call DSP generally has two understandings, one is the demand side platform, that is, the DSP advertising demand side platform, which is an advertising concept originated in Europe and the United States, with precision marketing as the core concept.

In addition, DSP is also the abbreviation of Dicital Signal Processing, that is, digital signal processing, which is a new discipline developed after the birth of computers, and digital signal processing refers to the representation and processing of signals in a digital way.

Technical support for DSP

The offload of DSP devices and GPP of general-purpose processors, GPP is not designed to do intensive multiplication tasks, even some modern GPPs require multiple instruction cycles to do a multiplication. While DSP processors use specialized hardware to implement single-cycle multiplication, DSP processors also add accumulator registers to handle the sum of multiple products. Accumulator registers are usually wider than other side registers, adding extra bits called knots to avoid overflow.

Most DSPs use a Harvard structure, where the memory space is divided into two, one for programs and one for data. They have two sets of buses connected to the processor cores, allowing them to be accessed simultaneously. This arrangement doubles the bandwidth of the processor memory and, more importantly, provides both data and instructions to the processor cores, allowing the DSP to implement single-cycle MAC instructions.
