Very High Speed Vectorial Processors Using Serial Multiport Memory as Data Memory

. Complex scientific problems involving large volumes of data need a huge computing power. Memory bandwidth remains a key issue in high performance systems. This paper presents an original method of memory organization based on serial multiport memory components which allows simultaneous access to all ports without causing either conflict between them or suspension. The resulting process for information exchange gives a cost effective realization of a data memory for vector processors. The memory bandwidth can be considerably increased in a modular manner, without practical implementation constraints. Keywords : serial multiport memory, memory bandwidth, realignment network, vector processor. 1 Introduction Performance improvements in scientific processing may be made in 2 different ways : - by increasing the number of processors, connected to a common memory, [1, 2] or organized in networks [3]. Nowadays program parallelism in these computers is performed more or less automatically bu..
