Centralized high-performance memory

Centralized High Performance Memory. A multiprocessor system of AFPs may share a common, high-performance random access memory store (HPR) between processors. All system HPR requests sent from the external memory access units (XMAU) of the AFP s are managed by the Storage Access Controller (SAC). Multiple SAC s may be employed as memory requirements are expanded. Each SAC is capable of transferring data to and from the AFP array at a sustained rate of 6.4 billion bits per second. 

The external memory access unit provides the interface between the AFP and the central, high-performance, random access memory store. Each external memory access unit can provide peak data I/O rates of 3.2 billion bits per second and sustained I/O rates of 800 million bits per second. Thus, the total sustained capability of an Advanced Flexible Processor from the two ring port I/O units and the two external memory access units is 3.2 billion bits per second. 

B. CNS depressants produce their effects by interfering with transmission of information across central synapses. In the central nervous system anticholinergic compounds disrupt the high integrative functions of memory, problem solving, attention and comprehension. Relatively high doses produce toxic delirium that destroys the ability to perform any military task. 

Very advanced special-purpose computers, such as the Earth Simulator in Japan its raw speed is high, as is effectiveness of delivered performance. The machine takes advantage of memory-usage patterns in science and engineering applications by way of fast data paths between the central processing unit and main memory (cf. T. Dunning, Appendix D).
