The first processed data is generated in response to execution of a first subtask of a pipelined task on first data. The technique includes writing command information to the buffer. The command information is appended to the first processed data and is associated with execution of a second subtask of the pipelined task on second processed data. The technique includes executing the second subtask on the second processed data according to the command information received from the buffer at a conclusion of execution of the second subtask on the first processed data. The technique may include executing the first subtask based on the first data to generate the first processed data. Executing the second subtask may include triggering execution of an execution unit in response to the command information. ## Claims ### Claim 1 A method comprising: writing first processed data to a buffer, the first processed data being generated in response to execution of a first subtask of a pipelined task on first data; interleaving command information to an end of the first processed data in the buffer, the command information including configuration information and trigger information associated with execution of a second subtask of the pipelined task on second processed data; interleaving the second processed data to an end of the command information, the second processed data being generated in response to execution of the first subtask of the pipelined task on second data; and triggering execution of the second subtask on the second processed data according to the configuration information in response to receiving the trigger information from the buffer at a conclusion of execution of the second subtask on the first processed data. ### Claim 2 (depends on 1) The method, as recited in claim 1, further comprising: executing the first subtask based on the first data to generate the first processed data. ### Claim 3 (depends on 2) The method, as recited in claim 2, wherein the triggering execution of the second subtask comprises: triggering execution of an execution unit in response to the trigger information. ### Claim 4 (depends on 1) The method, as recited in claim 1, wherein execution of the second subtask comprises: configuring an execution unit associated with the second subtask based on the configuration information. ### Claim 5 (depends on 1) The method, as recited in claim 1, wherein the configuration information comprises filter tap information. ### Claim 6 (depends on 1) The method, as recited in claim 1, wherein the configuration information comprises execution unit history information. ### Claim 7 (depends on 1) The method, as recited in claim 1, wherein the configuration information comprises size information associated with the second processed data. ### Claim 8 (depends on 1) The method, as recited in claim 1, wherein the first processed data and the second processed data are associated with adjacent fundamental blocks of a video frame. ### Claim 9 (depends on 1) The method, as recited in claim 1, wherein the configuration information includes boundary information for adjacent fundamental blocks of the video frame. ### Claim 10 (depends on 1) The method, as recited in claim 1, wherein the triggering execution of the second subtask is independent of a pipeline controller. ### Claim 11 An apparatus comprising: a first execution unit configured to: write first processed data to a buffer, the first processed data being generated by execution of a first subtask of a pipelined task on first data to a buffer, interleave command information associated with execution of a second subtask on second processed data to an end of the first processed data in the buffer, the command information including configuration information and trigger information, and interleave the second processed data to an end of the command information, the second processed data being generated in response to execution of the first subtask of the pipelined task on second data; and a second execution unit coupled in series with the first execution unit and configured to execute in parallel with the first execution unit, the second execution unit being further configured to execute a second subtask of the pipelined task on the first processed data and further configured to trigger execution of the second subtask on the second processed data according to the configuration information in response to receiving the trigger information from the buffer at a conclusion of execution of the second subtask on the first processed data. ### Claim 12 (depends on 11) The apparatus, as recited in claim 11, wherein the configuration information comprises filter tap information. ### Claim 13 (depends on 11) The apparatus, as recited in claim 11, wherein the configuration information comprises history information. ### Claim 14 (depends on 11) The apparatus, as recited in claim 11, wherein the configuration information comprises size information associated with the first processed data. ### Claim 15 (depends on 11) The apparatus, as recited in claim 11, wherein the second execution unit is configured to trigger execution of the second subtask in response to the configuration information. ### Claim 16 (depends on 11) The apparatus, as recited in claim 11, further comprising: the buffer configured to store the first processed data and the trigger information. ### Claim 17 (depends on 11) The apparatus, as recited in claim 11, wherein the first processed data and the second processed data are associated with adjacent fundamental blocks of a video frame and the configuration information includes boundary information for the adjacent fundamental blocks of the video frame. ### Claim 18 (depends on 11) The apparatus, as recited in claim 11, wherein the triggering execution of the second subtask is independent of a pipeline controller coupled to the first execution unit and the second execution unit. ### Claim 19 An apparatus comprising: means for generating and storing first processed data in a buffer, the first processed data being provided in response to execution of a first subtask of a pipelined task on first data; means for generating and storing configuration and trigger information interleaved with an end of the first processed data in the buffer, the configuration information being associated with a second subtask of the pipelined task on second processed data; means for generating and storing the second processed data interleaved with an end of the configuration and trigger information in the buffer; and means for executing the second subtask on the second processed data according to the command and trigger information in response to receiving the trigger information from the buffer at a conclusion of execution of the second subtask on the first processed data.
