- dfrage 7y agoOops, didn't read your comment closely enough, strike my above comment. Followed the Wikipedia link to the 1995 Fujitsu/HAL out-of-order design (https://en.wikipedia.org/wiki/HAL_SPARC64 https://en.wikipedia.org/wiki/HAL_SPARC64) and it says it's superscalar, but then that the first version can execute as many as 4 instructions at once and out-of-order. And from the very first version had branch prediction, which equals speculative execution as far as I know.
