Да, надо привести контекст. Речь идет о процессоре Cell:
In such a system, the cores may all use the same ISA, which allows an application to run on any of the cores, or may employ different ISAs, which can allow further tailoring of a core to a given task. IBM’s Cell Broadband Engine is an example of the latter. The Cell incorporates a single dual-issue in-order power processor element (PPE) with eight synergistic processor elements (SPEs). The SPEs use a new ISA, the SPU ISA, that is tailored to power efficiency for computationally intensive workloads. Although multiple programming paradigms are possible, the general idea is that the PPE handles most control and management decisions, such as dividing the workload among the SPEs, while the SPEs handle the majority of the computation.
