It consisted of parallel connected 166 vector processor

Vector processor

A vector processor, or array processor, is a central processing unit that implements an instruction set containing instructions that operate on one-dimensional arrays of data called vectors. This is in contrast to a scalar processor, whose instructions operate on single data items...

s with a gate delay as low as 60 ps in the Ga-As chips. The resulting cycle time was 9.5 ns. The processor had four independent pipelines each capable of executing two Multiply-Add instructions in parallel resulting in a peak speed of 1.7 Gflop/s per processor. Each processor board was equipped with 256 Megabytes of central memory.
