An Analysis of a Mesa Instruction Set Using Dynamic Instruction Frequencies, 1982
The Mesa architecture is implemented on a variety of processors, and dynamic instruction frequency data for two programs is used to analyze the architecture in an implementation independent fashion. The Mesa compiler allocates variables in an order based upon their static frequency of use, and measurements are provided that show that these static predictions predict run time usage as well. We p...
متن کاملProgram Algebra with Repeat Instruction
In the setting of program algebra (PGA) we consider the repeat instruction. This special instruction is designed to represent infinite sequences of instructions as finite, linear programs. The resulting program notation is called PGLA and can be considered a string syntax for PGA. We redefine the repeat instruction by allowing its counter to be also zero. Then we show that PGLAcore, a kernel of...
متن کاملInstruction-Isomorphism in Program Execution
This paper identifies a fundamental runtime program property: Instruction–Isomorphism. An instruction instance is said to be isomorphic if its component information derived from the instruction and its backward dynamic data dependence graph is identical to the component of an instruction executed earlier. By definition an isomorphic instruction will produce exactly the same output with the earl...
متن کاملScalar Program Performance on Multiple - Instruction
In this paper the performance of multiple-instruction-issue processors with variable register le sizes is examined for a set of scalar programs. We make several important observations. First, multiple-instruction-issue processors can perform eeectively without a large number of registers. In fact, the register les of many existing archi-tectures (16{32 registers) are capable of sustaining a hig...
متن کاملProgram algebra with unit instruction operators
In the setting of program algebra (PGA), a projection from PGAu, i.e., PGA extended with a unit instruction operator, into PGA is defined. This is done via a composition that employs backward jumps and (labeled) goto’s. © 2002 Elsevier Science Inc. All rights reserved.
