IA-64
Noun
(computing)
An
EPIC
64-bit
instruction
set
architecture
designed
to
allow
relatively
simple,
cheap
CPUs
to
execute
many
64-bit
instructions
simultaneously
and
with
potentially
very
high
performance;
developed
by
Intel
in
the
late
1990s
with
the
intent
of
replacing
the
older
x86
architecture,
but
was
delayed
and
proved
uncompetitive
with
x86
(especially
x86-64),
seeing
use
only
in
Intel's
own
Itanium
line
of
high-end
CPUs.
Japanese Meaning
IA-64は、比較的シンプルで安価なCPUが多数の64ビット命令を同時に高いパフォーマンスで実行できるように設計された、EPIC（Explicitly Parallel Instruction Computing）アーキテクチャに基づく64ビット命令セットである。 / 1990年代後半にIntelによって、従来のx86アーキテクチャの代替として開発されたが、開発の遅延や市場での競争力不足（特にx86-64に対して）により、最終的にはIntelのItaniumシリーズの高性能CPUでのみ採用された。
