tQUAD - Memory Bandwidth Usage Analysis

Abstract: One of the main issues in heterogeneous reconfigurable computing is the well-known processor/memory bottleneck. Due to the memory bandwidth limitations, the performance of execution of an application can dramatically increase via the efficient usage of the memory. In this paper, we present tQUAD, a new tool for the memory bandwidth usage analysis. This tool is capable of delivering detailed temporal memory bandwidth usage information for the functions in an application throughout a comprehensive analysis of th… Show more

“…It focuses on four main steps within the entire heterogeneous system design. The first step is related to application profiling [7], [8], [9] and coarse-grained task partitioning [10], [11], which is also the focus of this work. In the second step, finegrained hardware code segmentation is investigated along with possible parallelization of the code segments [12].…”

“…XQUAD [17] augments the memory access profiling data with extra information regarding individual data objects defined in the application source code. TQUAD [8] reveals the memory bandwidth usage of each function in terms of relative execution timings. All the tools in the QUAD toolset are implemented utilizing the Pin [18] Dynamic Binary Instrumentation (DBI) framework.…”
