چکیده
Disclaimer: " The contents of this document are scribe notes for The University of Texas at Austin EE382V Spring 2007, Computer Architecture: User System Interplay *. The notes capture the class discussion and may contain erroneous and unverified information and comments. This paper comes from industry. Transmetta's Crusoe microprocessor is a VLIW microprocessor that along with a software layer, the Code Morphing Software (CMS), provides a full implementation of the x86 architecture. The paper discusses the software system and the hardware support for implementing x86, specifically exceptions and interrupts, I/O, and self-modifying code.

The Transmeta Code Morphing - Software: Using Speculation, Recovery, and Adaptive Retranslation to Address Real-Life Challenges
Transmeta’s Crusoe microprocessor is a full, systemlevel implementation of the x86 architecture, comprising a native VLIW microprocessor with a software layer, the Code Morphing Software (CMS), that combines an interpreter, dynamic binary translator, optimizer, and runtime system. In its general structure, CMS resembles other binary translation systems described in the literature, but it is uni...

متن کاملBOA: The Architecture of a Binary Translation Processor
High frequency design and instruction-level parallelism (ILP) are two keys to high performance microprocessor implementation. To achieve these sometimes competing goals, the Binary-translation Optimized Architecture (BOA) aims to bring code translation techniques based on continuous profiling into the mainstream. Initially, code is interpreted to detect code hot spots and gather profile informa...

متن کاملOptimal Combined and Adaptive Protection of Active Distribution Networks Considering Different System Topologies Incorporating Optimal Selection of Standard Relay Curves
The change in the topology of active distribution networks (ADNs) is one of the essential challenges that might affect the protection schemes. The conventional protection schemes based on base topology result in some coordination constraint violations in other topologies due to the outage of upstream substations and distributed generation units. In this article, new combinational and adaptive p...
