一些专业术语的总结
VLIW:(Very Long Instruction Word,超长指令字)一种非常长的指令组合,它把许多条指令连在一起,增加了运算的速度。 超长指令字(VLIW)是指令级并行,超线程(Hyper-Threading)是线程级并行,而多内核则是芯片级并行。这三种方式都是提高并行计算性能的有效途径。其中,VLIW(超长指令字)体系结构是美国Multiflow和Cydrome公司于20世纪80年代设计的体系结构,EPIC体系结构就是从VLIW中衍生出来的。
CIF camera: In a digital camera, CIF, which stands for Common Intermediate Format, refers to the camera’s video recording technology that has a standardized resolution setting. Because it's a low-resolution video recording technology, CIF is typically found on smaller electronic devices that are capable of recording video, such as mobile phones and low-end digital cameras. A CIF camera is simply one of these types of devices that use CIF technology to record video
Demosaic: 去马赛克
round-robin arbitration : 循环仲裁
one-hot code: 独热码。例如,有6个状态的独热码状态编码为:000001,000010,000100,001000,010000,100000。
odd, even: 奇数,偶数。
a strobe light 闪光灯
and vice versa 反过来也一样
a progressive scan or interlaced scan mode 逐行扫描或隔行扫描模式
off-chip 表示外接的
the most significant 8 bits(MSB),the least significant(LSB) 最高位, 最低位
EMI : 电磁干扰
chunked: 分块的.
slot cycle: 时隙周期
OSC: 石英晶体振荡器(Quartz Crystal OSC)就是一种最常用的时钟信号振荡源。 在原理图上就是指时钟源
buck converter 降压变换器
晶圆被切割成矩形块,每个被称为“die”。每个好的die 被焊在“pads”上的铝线或金线,连接到封装内,pads通常在die的边上
SPS简介:
SPS(sample per sencond,每秒采样次数),是衡量数模转换(ADC)时采样速率的单位。注意采样速率和转换速率的区别,数模转换是先采样再转换,采样速率小于等于转换速率的采样才是有意义的。类似的单位有KSPS(每秒采样多少千次)、MSPS(每秒采样多少兆次)等
CKPOL (Clock Polarity) = CPOL = POL = Polarity = (时钟)极性
CKPHA (Clock Phase) = CPHA = PHA = Phase = (时钟)相位
die, 被封装的集成电路裸片;
die-pad, 用以焊装集成电路裸片的电路板;
molding compound,集成电路的塑封。
ROI(Region of Intrest -- 感兴趣,关心的区域)
