An information processing apparatus includes a detection unit and first and second classification units. The detection unit detects an event which causes a state of at least one bank constituting dynamic random access memory (DRAM) to transition. The first classification unit classifies the at least one bank state based on the detected event. The second classification unit classifies a DRAM state based on the at least one bank state. Statistical information that is based on the at least one bank or DRAM state is displayed with respect to a predetermined unit time. The at least one bank state and the DRAM state each includes at least one of the following: an operating state, in which data is being transferred, an inoperative state, in which data transfer is not possible due to a predetermined constraint, or a pause state, in which, although there is no constraint, data is not being transferred.

Information processing apparatus and information processing method to analyze a state of dynamic random access memory (DRAM)

An image forming apparatus which forms a halftone image on a print medium by using a multipass process to scan a printhead N (N is an integer of 2 or more) times in a single area on the print medium and form dots by each scan operation includes a pass division unit which sets the print density of a scan operation in the first pass so as to prevent dots from overlapping with each other on the print medium, and sets the print densities of scan operations in the second to Nth passes, a tone reduction unit which generates print data of the respective scan operations in accordance with the print densities set by the pass division unit, and a printhead which prints a halftone image on a print medium on the basis of the print data generated by the tone reduction unit.
