A digital signal processor (DSP) is a specialized microprocessor designed for processing digital signals. DSPs are used in applications such as audio and video processing, telecommunications, and control systems. They can perform complex mathematical operations quickly and accurately. Boxing Microservices architecture is a software development approach that involves breaking a large application into smaller, independent services that can communicate with each other using APIs. Microservices can provide flexibility, scalability, and fault isolation. Popular microservices platforms include Kubernetes, Docker Swarm, and Istio.
