Appeal No. 1999-2295
Application No. 08/418,797
first processor including a first cache configured to store a
head pointer of the buffer queue and a second processor including
a second cache configured to store a tail pointer of the buffer
queue. Appellant asserts at pages 8 and 9 of the specification
that the caches are made independent of each other, thereby
eliminating the need for a shared memory for storing head and
tail pointers.
Claim 1 is illustrative of the invention and reads as
follows:
1. A service module, comprising:
a buffer queue that stores a data queue, the
buffer queue comprising a plurality of buffers being
linked to one another as a linked list using next
pointers;
a first processor including a first cache coupled
to the buffer queue; and
a second processor including a second cache
coupled to the buffer queue,
wherein the first processor is configured to store
a head pointer of the buffer queue in the first cache
and the second processor is configured to store a tail
pointer of the buffer queue in the second cache, the
first cache being independent of the second cache.
