无论如何,给定坐标,一个程序可以快速有效的访问任意坐标点,在这个层面上来说,数据项的选择是任意的,无论要寻找哪个数据项,找到它都需要它的地址,也就是说,它所位于的坐标。一开始是用术语"random access",因为process不管在哪个序列都能根据需求找到记录,然而很快,大家觉得术语"direct access"更贴切,因为不管记录在...
(microprocessor-type) device to a sequential-access type device, such as EISA (Extended Industry Standard Architecture)-bus-memory (RAM) cell array (110), employed is a dual-port random-access-memory (RAM) cell array (110), for storing/retrieving words of data and a set of command and ...
The current design methods use standard static random access memory devices (SRAMs) and first-in-first-out memory devices (FIFOs). In many cases, dual-port RAM devices are the best design solutions to obtain the required throughput bandwidth. A new dual-port RAM, called the SARAM, offers...

making random access almost as fast as sequential access. This type of issue makes the argument for a metrics-based optimizer for SQL – one that actually looks as the results of using different query plans and factors this in when determining a plan, rather than simply the estimates of ...
In fact, the cache miss penalty can vary by almost one or two orders of magnitude among different policies because of tremendous divergence between sequential access rate and random access rate of disk. We notice the phenomena and propose a novel cache management policy, namely, Sequential Access...
