Operation analysis apparatus, operation analysis method, and computer program product

摘要

An image forming apparatus includes a storage unit, an arbitration unit that controls access to the storage unit, and a plurality of image processing units that are connected to the arbitration unit and access the storage unit via the arbitration unit. And, an operation analysis apparatus includes: an access monitoring unit monitoring which of the image processing units the arbitration unit permits access to the storage unit; a log generation unit generating, in response to the fact that the access monitoring unit detects that the image processing unit with access permitted has been switched, information on the image processing unit with access permitted as a log; a log storage unit storing therein the generated log; and a remaining capacity determination unit determining whether the storage capacity of the log storage unit after storing the log has become equal to or smaller than a particular capacity.

1. An operation analysis apparatus for analyzing operation of an arbitration unit included in an image forming apparatus comprising a storage unit, the arbitration unit configured to control access to the storage unit, and a plurality of image processing units configured to be connected to the arbitration unit, access the storage unit via the arbitration unit, and perform respective different pieces of image processing on image data, the operation analysis apparatus comprising:
a test circuit configured to monitor which of the image processing units the arbitration unit permits access to the storage unit; a log generation unit configured to, in response to the fact that the access monitoring unit detects that the arbitration unit has switched the image processing unit with access to the storage unit permitted, generate information on the image processing unit with access permitted as a log; a log storage unit configured to store therein the generated log; a remaining capacity determination unit configured to determine whether the storage capacity of the log storage unit after storing the log has become equal to or smaller than a desired capacity; a selection unit configured to receive selection of the image processing unit; and the log generation unit, in response to the fact that the access monitoring unit detects start of access to the storage unit by the selected image processing unit, is configured to start the generation of the log.
