With the SIMT execution model, GPUs can hidememory latency through massive multithreading for many applications that have regular memory access patterns. To support applications with irregular memory access patterns, cache hierarchies have been introduced to GPU architectures to capture temporal and spatial locality and mitigate the effect of irregular accesses. However, GPU caches exhibit poor efficiency...
This paper proposes a remote terminal design of 1553B based on DSP (TMS320F2812), which is specially applicable to aviation airborne equipment. The bus of 1553B chip, structures of DSP and BU-61580 are simply introduced, also the hardware interface and software design between the DSP and agreement interface are illuminated.
Vortex flow meter is widely used in industries because of its many advantages. However, it is subjected to the influence of noise when it works at low flow rate. The useful vortex signal is weak and easily drowned by noises, so it's measurement accuracy can't be ensured and the turn-down ratio is limited. In order to solve the problem, a secondary instrument system of vortex flow meter is presented...
Starting from the actual needs of network management, such as cabling topology graph auto-discovery which also contains room address-switch ports mapping mainly used in the post-maintenance, a method of hardware and software system integration solution to the management of practical problems encountered is proposed. To facilitate the integration, a telnet supported method of device interoperability...
To realize the breakthrough on underground coal mine rescue technology, studied one based on RFID personnel orientation rescuing system. The system is composed of transmitter and receiver. The miner carries a transmitter, once accident happens, the succor use the receiver to communicate with the transmitter at UHF band, and judging the direction where the miner is by observing the received signal...
In the study of prediction filed, no matter what methods we used, the main purpose is to minimize the prediction error; however, the goals cannot be fulfilled completely. Even we choose GM(1,1) model, which in the newest soft computing method, we also need to minimize the prediction error. Hence, in this paper, we focus on the influence parameter alpha in GM(1,1) model in the first, then, analyze...
