i486 - Wikipedia
The Intel 486, officially named i486 and also known as 80486, is a microprocessor introduced in 1989. It is a higher-performance follow-up to the Intel 386. It represents the fourth generation of binary compatible CPUs following the 8086 of 1978, the Intel 80286 of 1982, and 1985's i386.
Intel 80486 - 维基百科,自由的百科全书
Intel 80486 (又稱 486, i486)是 Intel 公司的一款 CISC 架構的 x86 CPU。 i486的前身是 Intel 80386 處理器。 從軟體的觀點來看,i486家族的指令集與 80386 非常相似,只有增加少量的指令。 [1] 不過從硬體的觀點來看,i486的結構有很大的突破。 它有內置資料快取晶片,DX型擁有一個浮點運算處理器,和多重管線。 在最佳的條件下,i486的核心可以提供一個時間週期內處理一個指令。 這會提供大約二倍同時脈的80386的效能。 然而,有些低等級的i486實際上會比最高速 …

The 486 provides more than twice the performance of the 386 microprocessor. The processor can address up to 4-Gigabytes of physical memory and 64-Terabytes (1-Terabyte = 1-K Gigabyte) of virtual memory. To implement a virtual memory system, the 486 supports full restartability for all page and segment faults.
