Using register renaming and physical registers, modern microprocessors eliminate false data dependences from reuse of the instruction set defined registers (logical registers). High performance processors that have longer pipelines and a greater capacity t ...
The development of more processing demanding applications on the Internet (video broadcasting) on one hand and the popularity of recent devices at the user level (digital cameras, wireless videophones, ...) on the other hand introduce challenges at several ...
Recent proposals for multithreaded architectures employ speculative execution to allow threads with unknown dependences to execute speculatively in parallel. The architectures use hardware speculative storage to buffer speculative data, track data dependen ...
Systems on chip are more and more heterogeneous and include software, analog/RF and digital hardware, and non-electronic components such as sensors or actuators. The design and the verification of such systems require appropriate modeling means to deal wit ...
Software transactional memory (STM) is a promising technique for controlling concurrency in modern multi-processor architectures. STM aims to be more scalable than coarse-grained locking and easier to use than fine-grained locks. However, STM implementatio ...
The growth and operation of all living beings are directed by the interpretation, in each of their cells, of a chemical program, the DNA string or genome. This process is the source of inspiration for the Embryonics (embryonic electronics) project, whose f ...
Distributed-memory parallel computers and networks of workstations (NOWs) both rely on efficient communication over increasingly high-speed networks. Software communication protocols are often the performance bottleneck. Several current and proposed parall ...
In this paper we introduce a new hardware/software approach to reduce the energy of the shared register file in upcoming embedded architectures with several VLIW processors. This work includes a set of architectural extensions and special loop unrolling te ...
For the last thirty years, electronics, at first built with discrete components, and then as Integrated Circuits (IC), have brought diverse and lasting improvements to our quality of life. Examples might include digital calculators, automotive and airplane ...
Automatic generation of Instruction Set Extensions (ISEs), executed on a custom processing unit or a coprocessor, is an important step towards processor customization. A typical goal of a manual designer is to combine a large number of atomic instructions ...
