Filed:

May 12, 2000

Appl. No.:

09/570211

Inventors:

David Ernst Finlay - Boulder CO, US
Phillip Keith Hoskins - Berthoud CO, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

H04N001/403
G06K015/00

US Classification:

358 115, 358 21, 358 299, 358 301

Abstract:

Disclosed is a method, system, and logic for processing pixel data. A first and second logic units each receive line work data and control data for pixels on a sheet from at least one object. The control data for one pixel indicates whether to use the line work data for the pixel or contone data for the pixel. Multiple objects may provide line work data and control data for a same pixel. The first and second logic units output control data indicating to use contone data or line work data for the pixel. A third logic unit receives the line work and control data outputted from the first and second logic units. The third logic unit then outputs control data indicating to use the contone data or line work data for the pixel.

David E. Finlay - Boulder CO

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G03G 1500

US Classification:

364900

Abstract:

International Classification:

G06F 309

US Classification:

364519

Abstract:

A character generator with multidirectional scan and variable line and character (or symbol) size capability is disclosed. Universality is implemented by producing a serial binary stream which can be used to print or display in any of eight combinations of scan direction and progression, that is, for scan direction left to right, or vice versa, progressing up or down, or scan direction top or bottom or vice versa, progressing left or right. In formatting the serial binary stream, a font is accessed (for basic symbol definition), which selectively provides for orthogonal scan of the symbol definitions. Variable line size is implemented by terminating a symbol row (or line) based on a predetermined size criteria regardless of the comparable font dimension and "filling" up to the line size to the extent the corresponding font dimension is less than the predetermined size criteria. Variable character (or symbol) size is implemented by independently multiplying the effect of a symbol definition by selected (integral) factors, in orthogonal directions. The general architecture includes a font table (for symbol definition), an address/escape (A/E) table, defining symbol size for comparison with line size parameters, a character position escape (CPE) table to define a leading character or symbol on each line and a page buffer (PB) memory defining the characters (symbols) in the document and their relationship with other characters (symbols).

5/937396

Inventors:

David E. Finlay - Boulder CO
Wayne E. Robbins - Longmont CO
Terence Travis - Boulder CO

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G03G 1500

US Classification:

364900

Abstract:

A copy production machine controlled by a programmed computer in which the computer control programs include synchronous and asynchronous portions. The asynchronous portions are repetitively executed in loop form for checking operating components and servicing operator control panels. The synchronous portions are executed in timed relation to the operation of the machine. The execution of the programs is coordinated via a set of memory registers accessible by the computer during execution of both program portions.

International Classification:

G06K 936

US Classification:

382 46

Abstract:

The invention provides a printer with a capability of printing in any one of a plurality of rotations. Component image data is stored in a library. The component image data is subdivided into data sets or quads. The size of a quad is selected so that it can be readily rotated with simple hardware. As the data sets are written to a buffer, they are rotated, and the locations in the buffer at which the different data sets are written depends on the selected rotation, to provide for data rotation "on the fly".

International Classification:

G06F 1300

US Classification:

364900

Abstract:

A common memory interfacing circuit and method for coupling a memory to either a synchronous bus or an asynchronous bus. Synchronizing means are provided for synchronizing memory request signals with a local clock when the interfacing circuit is coupled to an asynchronous bus. The interface circuit responds to signals from the memory when internal memory operation has been completed and generates an acknowledge signal to send to the requesting bus. To simplify the common interface circuit, a synchronous protocol for information exchange between system components is made similar to an asynchronous protocol.

Inventors:

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 1300

US Classification:

364900

Abstract:

A programmable controller includes a random access memory for storing signals relating to a plurality of programs executable in the controller. A portion of the memory addressing is zoned for enabling one or more programs to have exclusive access to that zone. The addressability of input/output registers, diagnostic registers and selected other units of common interest to all such programs are addressable in each of the plurality of zones as if such registers were uniquely assigned to such respective memory zones.
