Microblaze-Based Coprocessor for Data Stream Management System

Abstract

Data generation speed and volume have increased exponentially with the boom in Internet usage and with the advent of Internet of Things (IoT). Consequently, the need for processing these data faster and with higher efficiency has also grown in-over time. Many previous works tried to address this need and among them is Symbiote Coprocessor Unit (SCU), an accelerator capable of providing speedup of up to 150x compared with traditional data stream processors. The proposed architecture aims to reduce the complexity of SCU, making it flexible and still retaining its performance. The new design is more software driven and thus is very easy to be altered in the future if needed. We have also changed the older interface to industrial standard PCIe interface and AMBA AXI4 bus interconnect in order to make the design simple and open for future expansions.
