This work presents QTrace, an open-source instrumentation extension API developed on top of QEMU. QTrace instruments unmodified applications and OS binaries for uni- and multi-processor systems, enabling custom, full-system instrumentation tools for the x86 guest architecture. Computer architects can use QTrace to study whole program execution including system-level code. This paper motivates the...
This paper proposes a novel, fast, highly-parallel and configurable architecture for zigzag scan and optional scans in multiple video coding standards, including H.261, MPEG-1,2,4, H.264/AVC, and AVS. Arbitrary scan patterns could be supported by configuring the ROM data, and the proposed architecture can largely reduce the processing cycles. This makes it possible to integrate the scan unit into...
