Abstract
A vector processing computer (20) includes a memory control unit (22), main memory (99), a central processor (156), a service processing unit (42) and a plurality of input/output processors (54, 68). The central processor (156) includes a physical cache unit (100), an address translation unit (118), an instruction processing unit (126), an address scalar unit (142), a vector control unit (144), an odd pipe vector processing unit (148) and an even pipe vector processing unit (150). Vector elements are transmitted from memory, either main memory (99), a physical cache unit (100) or a logical cache (326) through a source bus (114) where the elements are alternately loaded into the vector processing units (148, 150). The resulting vectors are transmitted through a destination bus (114) to either the physical cache unit (100), the main memory (99), the logical cache (326) or to an input/output processor (54). In a still further aspect of the computer (20) there is included the logical data cache (326) which stores data at logical addresses such that the central processor (156) can store and retrieve data without the necessity of first making a translation from logical to physical address.
