Systems And Methods For Evaluation And Re-Allocation Of Local Memory Space

View page
US Patent:
20060161755, Jul 20, 2006
Filed:
Jan 20, 2005
Appl. No.:
11/039431
Inventors:
Takayuki Uchikawa - Austin TX, US
Yoshiyuki Hamaoka - Austin TX, US
Kazuko Ishibashi - Austin TX, US
International Classification:
G06F 12/00
US Classification:
711170000
Abstract:
Systems and methods for improving the efficiency of memory usage in a computing system by periodically evaluating the usage of local memory by each of the buffers implemented in the memory and changing the allocation of the local memory to the different buffers if necessary to improve the performance of the system. In one embodiment, after an initial allocation of local memory space to each buffer, the use of the local memory space by the buffers is evaluated using a function based upon static and dynamic factors. The allocation of local memory space to each buffer is based upon the results of the function. The evaluation and re-allocation is transparent to the processors using the buffers, and may be performed in response to an interrupt or expiration of a timer.

Method For Integrating Multiple Object Files From Heterogeneous Architectures Into A Set Of Files

US Patent:
20060095898, May 4, 2006
Filed:
Oct 28, 2004
Appl. No.:
10/976264
Inventors:
Alex Chow - Austin TX, US
Michael Day - Round Rock TX, US
Michael Gowen - Georgetown TX, US
Keisuke Inoue - Kanagawa, JP
James Xenidis - Carmel NY, US
Takayuki Uchikawa - Austin TX, US
Assignee:
International Business Machines Corporation - Armonk NY
Sony Computer Entertainment Inc. - Tokyo
Toshiba America Electronic Components, Inc - Irvine CA
Kabushiki Kaisha Toshiba - Tokyo
International Classification:
G06F 9/45
US Classification:
717140000
Abstract:
The present invention is a method for integrating multiple object codes from heterogeneous architectures. For a program on a first processor to reference a program from the name space of a second processor, the object code for the second-processor program is enclosed in a wrapper to create object code in the first-processor name space. The header of the wrapped object code defines a new symbol in the name space of the first processor, and the symbol points to the second-processor object code contained in the wrapped object code. Instead of directly referencing the second-processor object code, the referencing program on the first processor references the wrapped object code. A system tool can be used to wrap the object code which runs on the second processor.
