2. Different multithreaded approaches
2.1 Use of logic processors
Hardware support for multithreading means providing a physical processor with additional minimal physical resources: the execution context of each thread, which includes the program counter, all registers and status information. A logical processor therefore consists of this execution context and the common resources of the physical processor: computational operators, caches and main memory. Figure 3 compares a classic monothread processor with a multithread processor. The number of logical processors and the way they are switched between distinguish the different types of multithreading.
