2018年5月16日 · Looking through the table of instructions supported by the 8080, few others stand out as not being easy one-to-one translations, although as Peter Cordes points out …

2022年4月21日 · For the 8086, unaligned word loads (first byte at an odd address) require two memory accesses, but an aligned word (first byte at an even address) can be loaded in one. …

The 1979 version of the 8086 family user's manual is available at different places in the internet, see 1,2,3. It seems there is no newer version available. This manual documents the single …

2018年10月4日 · Its 8086 emulation is implemented in src/808x.c — you can see there that it keeps track of the cycles taken by each instruction, and each memory access, and takes into …

2020年2月16日 · The 8086 must wait for Busy before executing any other 8089 command. When done, the 8089 will reset the Busy-Flag 0h, signalling that the channel is finished. The same …

2021年3月9日 · Intel has named the i7-8086K in honor of the 8086 processor, though itself it is a 64-bit processor. And we still see in embedded systems or MIL-SPEC platforms there are old …

2018年6月3日 · The emulator implements a subset of the 8086 instruction set described here. I plan to implement bios routines for character I/O in int 10 and int 16 . But then I realized that …

A special feature of the 8042 is a built-in bus interface to allow it to easily integrate with Intel master CPUs like the 8086 - but it doesn't necessarily nead to run along one of them. The …

2019年7月26日 · The 8086 has no programmer-visible supervisor/user model in the instruction set architecture. However, it exposes a lot of state information through its pins, such as pins S0, …

2017年5月17日 · When the 8086 was designed, RAM was so valuable you couldn't simply assume some arbitrary value. On the other hand, you could most probably assume valid RAM …
