Appeal No. 2003-0031
Application No. 09/240,176
requires access to only a single circular buffer and control of
the access to the memory is achieved using a single set of
pointers for each circular buffer.
Claim 1 is illustrative of the invention and reads as
follows:
1. A memory controller having a plurality of channels,
the memory controller comprising:
input circuitry for receiving data to be stored in the
memory;
storage means for storing the base and top addresses of
a plurality of circular buffers in the memory to which the
received data is to be stored, and for storing a write
pointer for each buffer;
addressing circuitry for generating the address of one
of the plurality of circular buffers to which the received
data is to be written in dependence on a stored base and top
address and write pointer; and
output circuitry for writing the data into one of the
plurality of circular buffers at the generated address,
wherein at least one of the channels of the memory
controller is arranged to control the storage of data in one
of the plurality of circular buffers, and at least one of
the channels is arranged to retrieve data from only a
respective buffer.
The Examiner relies on the following prior art:
