It addition, arm processor is that Acorn computer Co., Ltd is towards low budget Market Design
First item risc microcontroller.It is referred to as Acorn RISC Machine earlier.Arm processor itself
It is 32 designs, but is also equipped with 16 bit instruction collection, save than 32 codes of equal value in general and reach
35%, but can retain being had superiority of 32 systems.
The Jazelle technology of ARM makes Java accelerate to obtain than Java Virtual Machine (JVM) based on software
Much higher performance, and equal non-Java acceleration nuclear phase is than lower power consumption 80%.On cpu function
Increase DSP instruction set and 16 and 32 arithmetic operation capabilities strengthened are provided, improve performance and spirit
Activity.ARM also provides for two forward position characteristics to be carried out subband and deeply embeds the highly integrated SoC device of processor
The debugging of part, they are embedded ICE-RT logic and the grand core of Embedded Trace (ETMS) series.
The three of arm processor are big, and feature is: little power consumption function is strong, 16/32 double instruction set and conjunction
Make partner numerous.Specifically possess following performance: 1, volume is little, low-power consumption, low cost, high-performance；
2, Thumb (16)/ARM (32) double instruction set are supported, can good compatibility 8/16
Position device；3, using register in a large number, instruction execution speed is faster；4, most of data manipulations are all
Complete in a register；5, addressing system is simple flexibly, and execution efficiency is high；6, command length is fixed.
It addition, image recognition, refer to utilize computer that image is processed, analyze and understand, with
Identify the target of various different mode and the technology to picture.
Image recognition is probably based on the principal character of image.Each image has his feature,
As letter A has point, P has a circle and there is individual acute angle etc. at the center of Y.Eye during image recognition is moved
Research show, sight line always concentrates in the principal character of image, namely concentrates on image outline
The place that curvature maximum or contour direction change suddenly, the information content in these places is maximum.And eyes
Scanning route forward to another feature from a feature the most successively.As can be seen here, at image
During identification, perceptual mechanism must get rid of the redundant information of input, extracts crucial information out, to pass
The information of key carries out characteristic matching, to obtain the target type identified.
Use the roller-coaster passenger status real-time detecting system of the present invention, in running for existing roller-coaster
Lack the technical problem of passenger's feedback mechanism, have employed image recognition technology and blood pressure detecting technology combines
Mode, accurately judge to take the passenger status of roller-coaster, and determine roller-coaster based on passenger status
The control strategy of operation conditions, thus the passenger for being in roller-coaster running provides feedback logical
Road, it is to avoid the body and mind of passenger is further damaged.
