Reducing cache memory requirements for recording statistics from testing with a multiplicity of flows

A computing device that processes a data feed including multiple streams, the computing system including an FPGA, the FPGA configured to perform operations comprising:

• processing n frames of the multiple streams in parallel through n processing pipelines, n being an integer greater than or equal to 2, the n frames including a first frame belonging to a first stream and a second frame belonging to a second stream, wherein the first stream is different than the second stream, the n processing pipelines being coupled to:
• n-by-n value buffers per stream per recorded value for the stream;
• and
• at least one status buffer per stream;
• wherein the n processing pipelines are each assigned a distinct row of read-authorized port access to the n-by-n value buffers and a distinct column of write-authorized port access to the n-by-n value buffers;
• and
• in a first processing pipeline:
• reading, for the first stream, a first row of the n-by-n value buffers using the read-authorized port to the value buffers in the row;
• reading a first status buffer to determine which of the value buffers in the first row contains a most recently updated value and processing the most recently updated value to produce a currently updated value;
• and
• writing the currently updated value to a first column of the n-by-n value buffers using the write-authorized port, while writing to the first status buffer to indicate that the first column of the value buffers has been updated with the most recently updated value.

A nontransitory computer readable medium storing an FPGA configuration that processes a data feed including multiple streams, which when loaded into an FPGA configures the FPGA to perform operations comprising:

• processing n frames of the multiple streams in parallel through n processing pipelines, n being an integer greater than or equal to 2, the n frames including a first frame belonging to a first stream and a second frame belonging to a second stream, wherein the first stream is different than the second stream, the n processing pipelines being coupled to:
• n-by-n value buffers per stream per recorded value for the stream;
• and
• at least one status buffer per stream;
• wherein the n processing pipelines are each assigned a distinct row of read-authorized port access to the n-by-n value buffers and a distinct column of write-authorized port access to the n-by-n value buffers;
• and
• in a first processing pipeline:
• reading, for the first stream, a first row of the n-by-n value buffers using the read-authorized port to the value buffers in the row;
• reading a first status buffer to determine which of the value buffers in the first row contains a most recently updated value and processing the most recently updated value to produce a currently updated value;
• and
• writing the currently updated value to a first column of the n-by-n value buffers using the write-authorized port, while writing to the first status buffer to indicate that the first column of the value buffers has been updated with the most recently updated value.
