  • Death row inmate executed after glitch prevents appeal - News

    Less than 24 hours before his scheduled execution, the Supreme Court agreed to accept a case challenging the Constitutionality of lethal injections. They were seeking a stay of execution for him. As a last-ditch effort, they went directly to the Supreme Court, pushing back Richard’s execution by a few hours. Richard was injected with the deadly cocktail shortly thereafter, and was officially pronounced dead at 8:23 PM. Earlier this week, the Texas Court of Criminal Appeals agreed to postpone the execution of another death row inmate, 28-year-old Heliberto Chi, reportedly because of the ongoing Supreme Court battle. In their complaint, they say, "Judge Keller’s actions denied Michael Richard two constitutional rights, access to the courts and due process, which led to his execution....

  • Intel's New Pentium 4 Processor - Articles & reviews

    Intel is very proud on the branch prediction unit that aids the execution trace cache. I have still decided against discussing them in detail to keep this article from becoming my next book. The Rapid Execution Engine The above picture is actually showing all execution units of Pentium 4, including the 'Rapid Execution Engine' as well as the 'not-so-rapid' execution units. Basic part of the 'Rapid Execution Engine' are the two 'double-pumped' ALUs and AGUs. Simple µOPs that can be processed by the Rapid Execution Engine are executed in half a clock, which is obviously a very good thing. Instructions, making Intel's 'Rapid Execution Engine'-design sensible though not particularly amazing....

  • Intel's Pentium Performance Hangs on a Hyper-Thread - Articles & reviews

    Because the two threads share one set of execution resources, the HT can use resources that would be otherwise idle if only one thread was executing. The result is an increased utilization of the execution resources within each physical processor package. For example, one logical processor can execute a floating-point operation while the other logical processor executes an addition and a load operation. Even though there are twice as many logical processors available, they are still sharing one set of execution resources. So the performance benefit of another physical processor with its own set of dedicated execution resources will typically offer greater performance levels....
