The hardware logic compares the current stride and a stride M in the queue and compares the newest of the queued strides with a queued stride M+1, which is older than and adjacent to stride M. When the comparisons match, the hardware logic prefetches a cache line whose offset is the sum of the offset of the current load request and a stride M−1. Stride M−1 is newer than and adjacent to stride M in the queue.

By recording predicted accesses over time for a number of access requests, the MAP monitor develops a pattern of predicted memory accesses by executing threads. The pattern can be employed to assign resources at the shared cache, thereby managing memory more efficiently.

Code regeneration determination from selected metadata fingerprints
A fingerprint is computed from selected metadata of binary files, and used in determining whether to regenerate code-behind file(s). In one case, after ascertaining that a binary-file-set's current metadata-fingerprint differs from a previous metadata-fingerprint, the corresponding code-behind-file-set is regenerated. A code-behind file may also be regenerated, even though its current fingerprint matches its previous fingerprint, because its metadata has changed. If the current fingerprint matches the previous fingerprint and metadata is unchanged, regeneration can be avoided. The fingerprint may consist of, or merely contain, definitions of classes, properties, and other items, and may be limited to metadata that is used when generating the code-behind-file-set. System assemblies are not fingerprinted. Timestamps may be used. Metadata-fingerprint computation code and regeneration determination code are described.

The optical resonator (100) includes an optical cavity (102) and an optical element (104.1, 104.2) at either end thereof, operable to sustain a light beam (108) therein, characterized in that each optical element (104.1, 104.2) is a phase-only optical element operable to alter a mode of the beam (108) as it propagates along the length of the optical resonator (100), such that in use the beam (108) at one end of the optical resonator (100) has a Gaussian profile while the beam (108) at the other end of the optical resonator (100) has a non-Gaussian profile.
Echelle diffraction grating and its manufacturing method, excimer laser and its manufacturing method
A manufacturing method for an excimer laser that includes a reflective Echelle diffraction grating includes obtaining information of a wavelength of a light source, a blazed order, a repetitive pitch of the grating, a material of the grating, and a predefined orientation ratio B/A that is a ratio between that a diffraction efficiency A of the blazed order and a diffraction efficiency Bb of an order lower by one order than the blazed order, and determining an initial value of a blaze angle based upon these pieces of information.
Optical semiconductor device and method of manufacturing optical semiconductor device
A method of manufacturing an optical semiconductor device including: forming a mesa structure including a first conductivity type cladding layer, an active layer and a second conductivity type cladding layer in this order on a first conductivity type semiconductor substrate, an upper most surface of the mesa structure being constituted of an upper face of the second conductivity type cladding layer; growing a first burying layer burying both sides of the mesa structure at higher position than the active layer; forming an depressed face by etching both edges of the upper face of the second conductivity type cladding layer; and growing a second burying layer of the first conductivity type on the depressed face of the second conductivity type cladding layer and the first burying layer.
Low inductance laser diode bar mount
The laser mount arrangement can have a laser bar and a driver positioned adjacent to one another and secured against a connection face of a heat sink base. The heat sink base is connected to and forms a first electrical connection between the laser bar and the driver. A second electrical connection is also provided between the laser bar and the driver opposite the heat sink base, which can be in the form of a flexible metal sheet with a narrow upward fold. This arrangement can provide a low inductance path for the current.
