PPT-1 Notation and Specification of Concurrency

Concurrency Topics 1 Sequential programming notation 2 Expressing concurrency with co and process 3 States and hardware 4 Atomic actions 5 Interleavings and histories 6 The finite progress assumption. Consider the coordinate system illustrated in Figure 1 Instead of using the typical axis labels and we use and or 1 The corresponding unit basis vectors are then and or 1 The basis vectors and have the following properties 1 1 0 2 Figu Lecture 1. 1.
