7 TickTockTokens
7 : TickTockTokens
- Author: Johannes Leugering
- Description: Implementation of a processor that uses Tick Tock Tokens for event-based computation.
- GitHub repository
- Clock: 10000000 Hz
How it works
Each TickTockToken (ttt) is indicated by two messages, a start and an end event. A ttt-Processor uses these tokens to perform event-based computations in a fashion inspired by Time Petri Nets.
How to test
If I didn't get lazy half-way though, the test-script provided in the repo should run a test model successfully, and the documentation should provide a more through explanation.
