Abstract
Abstract A computer system comprises a plurality of programs, each operating in an operating area such as a virtual machine. The programs are provided with a common data buffer for buffering data for processing by said programs. Each program also has a buffer control including at least one pointer for pointing to a buffer containing data to be processed by the program. One of the programs will initially process the data in the common data buffer and, after it is finished processing, will control the other program's buffer pointer to enable the other program to process the data in the common data buffer. By using the same buffer to contain data to be processed by both programs, the programs can avoid having to copy the data between private buffers maintained for each, which can assist in accelerating through-put by the computer system. <IMAGE>

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
82 words
A computer system comprising a plurality of programs each operating in an operating area and a common data buffer for buffering data for processing by said programs, each program having a buffer control including at least one buffer pointer for pointing to a buffer to be processed thereby, one of said programs processing the data in the common data buffer and thereafter controlling the other program's buffer pointer to enable said other program to process the data in the common data buffer.
Claim 2
Dependent Claim
34 words
A computer system as defined in claim 1 in which the buffer control comprises a linked list including a series of entries, each entry having a buffer pointer field for receiving a buffer pointer.
Claim 3
Dependent Claim
30 words
A computer system as defined in claim 2 in which each entry further includes a next entry pointer field for pointing to a next entry in the series of entries.
Claim 4
Dependent Claim
127 words
For use in connection with a computer system, a computer program product including a computerreadable medium having encoded thereon code devices for enabling the computer system to perform operations in an operational area and in connection with a common data buffer for buffering data for processing under control of said program and under control of other programs, said computer program product enabling the computer system to establish a buffer control including at least one buffer pointer for pointing to a buffer to be processed thereby, said program controlling the computer system to process the data in the common data buffer and thereafter control another program's buffer pointer to enable said computer system to, under control of said other program, process the data in the common data buffer.
Claim 5
Dependent Claim
35 words
A computer program product as defined in claim 4 in which the buffer control comprises a linked list including a series of entries, each entry having a buffer pointer field for receiving a buffer pointer.
Claim 6
Dependent Claim
31 words
A computer program product as defined in claim 5 in which each entry further includes a next entry pointer field for pointing to a next entry in the series of entries.
Claim 7
Independent Claim
109 words
A method of controlling a computer system in response to program, comprising the steps of A. enabling the computer system to perform operations in connection with the program in an operational area and in connection with a common data buffer for buffering data for processing under control of said program and under control of other programs, said program enabling the computer system to establish a buffer control including at least one buffer pointer for pointing to a buffer to be processed thereby, and B. controlling another program's buffer pointer to enable said computer system to, under control of said other program, process the data in the common data buffer.
Claim 8
Dependent Claim
33 words
A method as defined in claim 7 in which the buffer control comprises a linked list including a series of entries, each entry having a buffer pointer field for receiving a buffer pointer.
Claim 9
Dependent Claim
29 words
A method as defined in claim 8 in which each entry further includes a next entry pointer field for pointing to a next entry in the series of entries.
