A method, and associated system, for allocating memory to a first pipeline that includes a sequence of filters. Each filter is configured to execute a process specific to each filter, receive input data, and generate output data. The output data from each filter, except the last filter in the sequence, serves as the input data to the next filter in the sequence. An optimum memory capacity is allocated to the first pipeline if possible. Otherwise, a guaranteed memory bandwidth is allocated to the first pipeline if possible. Otherwise, extra memory currently allocated to a second pipeline is currently released if the second pipeline not currently performing processing or subsequently released when the second pipeline subsequently completes performing processing that is currently being performed, followed by allocating the extra memory to the first pipeline.

Method and system for allocating memory to a pipeline

A system includes a structure information obtaining unit which obtains structure information containing information on components of a development target in a project and on dependency relationships between the components, the structure information described, e.g., in SysML, a work item determining unit which determines work items and a work execution order based on the structure information obtained by the structure information obtaining unit; a detailed item determining unit; a date scheduling unit and a WBS storage which manages the determined work items and work execution order as work schedule definition information. The work item determining unit determines a work item related to a leaf component, which is a component not including any other component, and determines, in a case where all of the multiple components included in a single predetermined component are leaf components, a work item related to a coupling relationship between the leaf components.
