A single instruction, multiple data ("SIMD") computer system includes a
central control unit coupled to 256 processing elements ("PEs") and to 32
static random access memory ("SRAM") devices. Each group of eight PEs can
access respective groups of eight columns in a respective SRAM device.
Each PE includes a local column address register that can be loaded
through a data bus of the respective PE. A local column address stored in
the local column address register is applied to an AND gate, which
selects either the local column address or a column address applied to
the AND gate by the central control unit. As a result, the central
control unit can globally access the SRAM device, or a specific one of
the eight columns that can be accessed by each PE can be selected locally
by the PE.
