Second, a bytecode dispatch is a single direct memory read, followed by a single indirect branch. 其次,字节码调度程序只是一个简单地从内存中直接读取,转而间接调度分支程序的过程。
You've heard the adage before : memory read / writes are measured in nanoseconds, disk read / writes in milliseconds. 您一定听说过:内存读写以纳秒计,磁盘读写以毫秒计。
De-blocking filter need to read-write operation to the external memory, but not at full time, therefore, the filtering process used alternately with the external memory read and write. 去块滤波的滤波由于需要对外部存储器进行读写数据,但又不是随时都在进行,故采用滤波过程与外部存储读写交叉进行。
Image recognition module to complete : for digital image acquisition module control; the SDRAM memory read write control; to complete the uptake of the image recognition, and output quality type information code. 质量检测模块中完成:对图像数据样本发生的控制;对数字样本缓存的读写控制;完成对所摄取的图像识别,并输出代表质量类型的信息码。
The frame memory in the system is directly mapped to the computer ′ s memory address space. High speed memory read and write can be realized. 该系统通过标准ISA总线与计算机接口,帧存直接映射计算机内存地址空间,存取速度快。
