Abstract: A computer has instruction pipeline circuitry capable of executing two instruction set architectures (ISA's). A binary translator translates at least a selected portion of a computer program from a lower-performance one of the ISA's to a higher-performance one of the ISA's. Hardware initiates a query when about to execute a program region coded in the lower-performance ISA, to determine whether a higher-performance translation exists. If so, the about-to-be-executed instruction is aborted, and control transfers to the higher-performance translation. After execution of the higher-performance translation, execution of the lower-performance region is reestablished at a point downstream from the aborted instruction, in a context logically equivalent to that which would have prevailed had the code of the lower-performance region been allowed to proceed.

Abstract: A tool box in which tools, hardware, parts, and the like stored therein can be displayed, accessed, and retrieved in a quick, convenient, and efficient manner. Tools, hardware, and the like can be displayed and distinguished one from the other, accessed, removed, and stored quickly, and easily. The tool box has mating hinged container portions and mating hinged cover portions that may be pivotally opened for display, access, and retrieval of tools, hardware, and the like stored therein in a quick, convenient, and efficient manner and distinguished one from the other, accessed, removed, and stored quickly, and easily or closed for storage and transport, and display storage cases that may be removably and pivotally adjoined one to the other. The tool box is durable, light weight, inexpensive, safe to use, attractive, sturdy, and of simple construction, and may be of metal, such as aluminum or steel, thermoplastics, thermosetting polymers, rubber, or other suitable material or combination thereof.
