ABSTRACT:
A second memory stores data in units of segments. An assignment control circuit sets up a buffer space as a logical address space. A buffer space is formed as a set of at least one segment. A state storage circuit stores association between a buffer space and segments as segment assignment information. An address conversion circuit refers to segment assignment information to convert a logical address into a physical address. A segment queue stores a free segment and a buffer queue stores a free buffer. The state storage circuit includes a plurality of register groups each of which includes a plurality of segment registers. A register group is associated with one of the plurality of buffer spaces. A range number identifying a range of logical addresses in the associated buffer space is set up in a segment register.
