A processor is operative to execute two or more instruction sets, each in a different instruction set operating mode. As each instruction is executed, debug circuit comparison the current instruction set operating mode to a target instruction set operating mode sent by a programmer, and outputs an alert or indication in they match. The alert or indication may additionally be dependent upon the instruction address following within a predetermined target address range. The alert or indication may comprise a breakpoint signal that halts execution and/or it is output as an external signal of the processor. The instruction address at which the processor detects a match in the instruction set operating modes may additionally be output. Additionally or alternatively, the alert or indication may comprise starting or stopping a trace operation, causing an exception, or any other known debugger function.

Disclosed is a flex die punching apparatus for forming an aperture in at least one sheet of material. There is a flexible, extrudable platen which, upon exertion of a force against it, extrudes at least a portion of at least one sheet of material through an aperture of a die. The flexible, extrudable platen may have a punch feature, corresponding to the shape and position of the die aperture, which assists in the extruding of the flexible, extrudable platen through the die aperture and also in the formation of the aperture in the sheet of material. In another embodiment of the invention, there may be a second die wherein the at least one sheet of material is placed between the first and second dies to form the aperture in the sheet of material.

Flex die punching apparatus and method

Method for thermally-machining large area features, and screen-depositing metallurgy on a ceramic dielectric greensheet. The method comprises an improvement over the conventional integrated disposable mask process, and involves the steps of outlining the large feature areas through a masking film laminated to a greensheet, using a high intensity energy beam such as a laser beam, electron beam, photon beam, etc, forming a stencil sheet having corresponding large area feature openings, and laminating the stencil sheet in registration over the masking film. An adhesive sheet is pressed against the back of the stencil sheet, through the stencil openings, to adhere to the outline features on the masking film and to remove them when the stencil sheet is separated from the masking film. Conductive paste is applied to the greensheet, through the large feature openings in the masking film, and the electroded greensheet is fired for use in preparing multi-layer ceramic packages.

A debris control system is provided for an electron-beam drilling apparatus having a chamber encompassing a drilling area and a calibration area. The debris control system includes a calibration-area shielding assembly which shields a calibration area of such apparatus from drilling-generated debris and an isolation assembly which isolates drilling-generated debris within such drilling area.

Debris control system

A high precision system for machining substrates by means of an energy beam includes real time digital signal processor control and a deflection system providing control, within a predetermined field of the substrate, of the angle at which the beam machines the substrate. An electron beam is used in a vacuum chamber in a preferred embodiment. The system also includes an x-y table for positioning the substrate and may have provision for detecting the x-y position and angular misregistration of the substrate. Dynamic forms and stigmator control may be used to produce a uniform beam within the field. The system allows a high speed vector machining process, which optimizes the overall system throughput by minimizing the settling time of the deflection system.
