A digital computer system automatically creates an Instruction Set Architecture (ISA) that potentially exploits VLIW instructions, vector operations, fused operations, and specialized operations with the goal of increasing the performance of a set of applications while keeping hardware cost below a designer specified limit, or with the goal of minimizing hardware cost given a required level of performance.

Apparatus and method are described for fast code coverage analysis. The present invention for fast code coverage analysis utilizes a technique that provides for capturing an event every first time that a block of code is visited. This allows for generating an event only once during numerous executions of a code block. The generation of only one event provides for an execution time close to the speed of the original source code.

The present invention relates to a tunable compensation device and method for received signals. The tunable compensation device comprises a first antenna, a compensation device, a second antenna and a signal processing unit. The first antenna receives a first radio wave. The compensation device receives and compensates the first radio wave. The second antenna receives a second radio wave. The signal processing unit receives the compensated first radio wave and the second radio wave as to control the compensation by the compensation unit for the first radio wave. The tunable compensation method is characterized in that the first radio wave received by the first antenna is used to modulate the second radio wave received by the second antenna.

System and method are described for register optimization during code translation utilizes a technique that removes the time overhead for analyzing register usage and eliminates fixed restraints on the compiler register usage. The present invention for register optimization utilizes a compiler to produce a register usage bit vector in a NOP instruction within each basic block (i.e., subroutine, function, and/or procedure). Each bit in the bit vector represents a particular caller-saved register. A bit is set if, at the location of NOP instruction, the compiler uses the corresponding register within that basic block containing the NOP instruction to hold information to be used at a later time. During the translation, the translator examines the register usage bit vector to very quickly determine which registers are free and therefore can be used during the register optimization without the need to save and restore the register values.
