A key component of the Data-Intensive Architecture (DIVA) is the Processing-In-Memory (PIM) Routing Component (PiRC) that is responsible for efficient communication between PIM chips. This paper presents the design of a low area, delay and power router for DIVA. A 58.5% saving in area and 86% reduction in load on the clock as compared to an earlier PIM router design makes the presented design ideal for use in the second version of DIVA, with low area being a critical design requirement for DIVA. This paper also gives a comparison of the presented design with an earlier PIM router design in terms of delay and power to justify the new design choice.
