Application 08/294,765
a second device including an information lookup database comprising a plurality of
entries, each one of the plurality of entries containing information relating to a
corresponding request; and
a request/response memory coupled to each of the first and second devices to
interlock the first and second devices for an exchange of information;
the first device operating to communicate to the second device, via the
request/response memory, by said requests for information , each of the plurality of said
requests for information, including request data and request ownership information being
transmitted in a single write transaction to the request/response memory;
the second device operating to use the request data from each of the plurality of
said requests as a lookup index to the lookup database for access to and retrieval of a
corresponding one of the entries to generate a response including response data and
response ownership information, and to communicate each response to the first device,
via the request/response memory, for use by the first device in processing the input data;
the request/response memory comprising a plurality of entries, each of the entries
including a request storage memory space for storing a request by the first device and a
response storage memory space for storing a corresponding response by the second
device, the request storage memory space for each entry being accessible to both the first
and second devices;
the request storage memory space of each one of the entries including a first
preselected memory location for storage of request ownership information and a second
preselected memory location for storage of request data;
the response storage memory space of each one of the entries including a third
preselected memory location for storage of response ownership information and a fourth
preselected memory location for storage of response data;
wherein the request ownership information of the first preselected memory location
indicates whether the request data stored in the respective request storage memory space
by the first device is valid for use by the second device and the response ownership
information of the respective third preselected memory location indicates whether the
