Apollo PRISM
PRISM (Parallel Reduced Instruction Set Machine) was Apollo Computer's high-performance CPU used in their DN10000 series workstations. It was for some time the fastest microprocessor available, a high fraction of a Cray-1 in a workstation. Hewlett Packard purchased Apollo in 1989, ending development of PRISM, although some of PRISM's ideas were later used in HP's own HP-PA RISC and Itanium processors.
PRISM was based on what would be known today as a VLIW-design, while most efforts of the era, 1988, were based on a more "pure" RISC approach. In early RISC designs, the core processor was simplified as much as possible in order to allow more of the chip's real-estate to be used for registers and simplifying the addition of instruction pipelines for improved performance.

Famous quotes containing the words apollo and/or prism:
“blue bead on the wick,
there’s that in me that
burns and chills, blackening
my heart with its soot,
I think sometimes not Apollo heard me
but a different god.”
—Denise Levertov (b. 1923)
“Neither can I do anything to please critics belonging to the good old school of “projected biography,” who examine an author’s work, which they do not understand, through the prism of his life, which they do not know.”
—Vladimir Nabokov (1899–1977)
