摘要:
A synchronous data processing system includes a memory module to store data and a memory controller coupled to the memory module. The memory controller includes a clock inverter to receive an input clock signal and to transmit an inverted clock signal to the memory module. The inverted clock signal incurs a first propagation delay prior to reaching the memory module as a memory clock signal. A write data buffer is coupled to the memory module. The write data buffer transmits data to the memory module in response to the input clock signal. An asynchronous first-in-first-out (ASYNC FIFO) buffer is coupled to the memory module. The ASYNC FIFO buffer reads data from the memory module in response to a feedback signal generated by feeding back the memory clock signal to the ASYNC FIFO buffer.

A system and method for monitoring system including a embedded sensor coupled to an article, wherein the embedded sensor is a direct write embedded sensor using a high temperature light emitting material. A camera system detects illumination signals from the embedded sensors. A processing section processes the illumination signals and determines gas/surface temperatures and strain data for the article.

A method and system for booting an electronic device from a NAND flash memory includes a NAND flash controller that receives an event trigger for fetching a pre-boot code stored in the NAND flash memory. Based on the event trigger type, booting parameters are loaded into the controller including a boot frequency of the NAND flash memory. The controller searches for a good memory block in which the pre-boot code is stored by checking the first and second or the first and last pages of a memory block and fetches a portion or the entire pre-boot code based on the event trigger type at the boot frequency.

A method for forming a graded matching layer structure is presented. The method includes (a) depositing a first material slurry on at least a portion of a substrate, (b) spreading the first material slurry to a form a first material layer having a first determined thickness, (c) exposing the first material layer using light processed through a determined light pattern mask to form a first matching layer, and (d) repeating steps (a)-(c) with different material slurries to form the graded matching layer structure.

A system and method for monitoring system including a three dimensional embedded sensor coupled to an article, wherein the three dimensional embedded sensor is a direct write embedded sensor using a high temperature light emitting material. A camera system detects illumination signals from the embedded sensors. A processing section processes the illumination signals and determines gas/surface temperatures and strain data for the article.

An inspection artifact includes a central portion and multiple optical and coordinate measurement machine (CMM) alignment features arranged on the central portion. The optical and CMM alignment features are configured to align the coordinates for an optical or a CMM measurement system to a common coordinate system. Another inspection artifact includes a central portion and multiple computed tomography (CT) alignment features arranged on the central portion. The CT alignment features are configured to align the coordinates for a CT system to a common coordinate system.
