It is a visual representation that helps in modeling the dynamic aspects of a system, particularly its lifecycle. ### Key Components of a State Diagram: 1. **States**: These are the conditions or situations during the life of an object or system.
Stochastic computing 1970-01-01
Stochastic computing is a computing paradigm that represents data as probabilities rather than using traditional binary representations (0s and 1s). In stochastic computing, a value is encoded as a stream of bits where the probability of a bit being '1' corresponds to the value being represented. For example, if a number is represented as a stochastic bit stream of length \( N \), the ratio of '1's to '0's in that stream can represent a value between 0 and 1.
Stream X-Machine 1970-01-01
The Stream X-Machine is a theoretical concept in computer science and automata theory. It's a variant of finite state machines (FSMs) that processes input streams rather than discrete inputs. The primary aim of the Stream X-Machine is to model and analyze computations that are inherently sequential and continuous, particularly in the context of real-time applications.
