Abstract: In an information processing apparatus (10) that includes a cache memory (560) formed from at least one hierarchy, and a pre-fetch command that speculatively transfers data or a command from a main storage (30) to the cache memory, a cache controller (510) provides control to execute the pre-fetch command such that a virtual address is converted to a physical address using a conversion table, and the virtual address and the physical address are stored as a pair if the conversion succeeds.

Abstract: In order to increase the operation efficiency of the operation register for holding store data when executing store instruction to store data in a predetermined store area on the main memory or the cache memory, in the present invention, an instruction processing section is adapted so as, when an operation register holding the operation result is determined, causes the operation result to be issued from the operation register to store buffers as store data; when the store data are held by the store buffers before the store instruction is held by store ports, a restraint section restrains a reset section from setting a store data hold flag to OFF at a point of time when the store instruction is held by the store ports to maintain the store data hold flag to ON.

Abstract: A store data control device that controls a store buffer and a write buffer that temporarily retains store data, and that executes a merging process on store data when transferring store data from the store buffer to the write buffer. The store data control device acquires a buffer state of at least one of the store buffer and the write buffer, and based on the buffer state acquired controls whether to start or cancel a queuing process corresponding to the merging process.

Abstract: A central processor executes at least a load command, a store command, and a prefetch command based on an out-of-order processing for processing commands by changing the order of executing the commands. A valid MIB detector detects the number of primary cache MIBs that hold requests of a primary cache for reference to data stored in the main storage. An MIB controller controls to hold in the primary cache MIBs the reference requests according to the load command or the store command in preference to the reference requests according to the prefetch command, when the detected number of the cache buffers reaches a predetermined number.

Abstract: A central processing device includes a plurality of sets of instruction processors that concurrently execute a plurality of threads and primary data cache devices. A secondary cache device is shared by the primary data cache device belonging to different sets. The central processing device also includes a primary data cache unit and a secondary cache unit. The primary data cache unit makes an MI request to the secondary cache unit when a cache line with a matching physical address but a different thread identifier is registered in a cache memory, performs an MO/BI based on the request from the secondary cache unit, and sets a RIM flag of a fetch port. The secondary cache unit makes a request to the primary cache unit to perform the MO/BI when the cache line for which MI request is received is stored in the primary data cache unit by a different thread.

Abstract: A laser depilator comprising a unit for removing hairs from the skin, a light source for irradiating laser light, and a lens for irradiating the skin with the laser light irradiated from the light source while deforming the beam shape so as to conform to the shape of a region of the skin from which hairs are removed by the hair removing unit.
