Design tools for application specific instruction set processors (ASIPs) are an important discipline in system-level design for wireless communications and other embedded application areas. Some ASIPs are still designed completely from scratch to meet extreme efficiency demands. However, there is also a trend towards use of partially predefined,(More)
Current Application Specific Instruction set Processor (ASIP) design methodologies are mostly based on iterative architecture exploration that uses Architecture Description Languages (ADLs) and retargetable software development tools. However, for improved design efficiency, additional pre-architecture exploration tools are required to help narrow-down the(More)
With the growing number of programmable processing elements in today's <i>Multi Processor System-on-Chip</i> (MPSoC) designs, the synergy required for the development of the hardware architecture and the software running on them is also increasing. In MPSoC development environment, changes in the hardware architecture can bring in extensive re-partitioning(More)
Instruction Set Simulation (ISS) is widely used in system evaluation and software development for embedded processors. Despite the significant advancements in the ISS technology, it still suffers from low simulation speed compared to real hardware. Especially for embedded software developers simulation speed close to real time is important in order to(More)
<i>Instruction Set Simulators</i> (ISSes) are important tools for cross-platform software development. The simulation speed is a major concern and many approaches have been proposed to improve the performance of ISSes. A prevalent technique is compiled simulation, which translates target programs into host instructions. But orders of magnitude of speed(More)
SIMD instructions are used to speed up multimedia applications in high performance embedded computing. Vendors often use proprietary platforms which are incompatible with others. Therefore, porting software is a very complex and time consuming task. Moreover, lots of existing embedded processors do not have SIMD extensions at all. But they do provide a wide(More)
Breast-conserving surgery followed by whole-breast irradiation is the standard local therapy for early breast cancer. The international discussion of reduced importance of wider tumor-free resection margins than "tumor not touching ink" leads to the development of five principles in targeted oncoplastic breast surgery. IORT improves local recurrence risk(More)
The growth of the Internet in the last decade has made current networking applications immensely complex. Systems running such applications need special architectural support to meet the tight constraints of power and performance. This paper presents a case study of architecture exploration and optimization of an Application Specific Instruction set(More)
