翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク nova ： FOLDOC Nova A minicomputer(?) introduced by Data General in 1969, with four 16-bit {accumulators}, AC0 to AC3, and a 15-bit program counter. A later model also had a 15-bit stack pointer and frame pointer. AC2 and AC3 could be used for {indexed addressing} and AC3 was used to store the return address on a subroutine call. Apart from the small register set, the NOVA was an ordinary CPU design. Memory could be accessed indirectly through addresses stored in other memory locations. If locations 0 to 3 were used for this purpose, they were auto-incremented after being used. If locations 4 to 7 were used, they were auto-decremented. Memory could be addressed in 16-bit words up to a maximum of 32K words (64K bytes). The instruction cycle time was 500 nanoseconds(?). The Nova originally used {core memory}, then later dynamic RAM. Like the PDP-8, the Data General Nova was also copied, not just in one, but two implementations - the スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016. All Rights Reserved.
