Data Centric Cache Measurement Using Hardware and Software Instrumentation

Title of Dissertation: DATA CENTRIC CACHE MEASUREMENT USING HARDWARE AND SOFTWARE INSTRUMENTATION Bryan R. Buck, Ph.D., 2004 Dissertation Directed By: Professor Jeffrey K. Hollingsworth, Department of Computer Science The speed at which microprocessors can perform computations is increasing faster than the speed of access to main memory, making efficient use of memory caches ever more important...

Counting performance: hardware performance counter and compiler instrumentation

Analyzing applications for their runtime behavior, especially in the light of ef®cient resource utilization, involves iterative measurements and the interpretation of the data gathered. For ®ne grained analysis often hardware performance counters are monitored. Since compiler instrumentation augments the program with calls to a measurement system, it interacts with compiler optimizations. Curre...

Automatic Instrumentation Technique of Embedded Software for High Level Hardware/Software Co-Simulation

We propose an automatic instrumentation method for embedded software annotation to enable performance modeling in high level hardware/software co-simulation environments. The proposed ”cross-annotation” technique consists of extending a retargetable compiler infrastructure to allow the automatic instrumentation of embedded software at the basic block level. Thus, target and annotated native bin...

Kernel Instrumentation Tools and Techniques Kernel Instrumentation Tools and Techniques

Atom is a powerful platform for the implementation of prooling, debugging and simulation tools. Kernel support in ATOM makes it possible to implement similar tools for the Digital UNIX kernel. We describe four non-trivial Atom kernel tools which demonstrate the support provided in Atom for kernel work as well as the range of application of Atom kernel tools. We go on to discuss some techniques ...
