86Box is a low level x86 emulator that runs older operating systems and software designed for IBM PC systems and compatibles from 1981 through fairly recent system designs based on the PCI bus.

EMU8086 - MICROPROCESSOR EMULATOR is a free emulator for multiple platforms. It provides its user with the ability to emulate old 8086 processors, which were used in Macintosh and Windows computers from the 1980s and early 1990s. It can emulate a large amount of software that was used on these microprocessors, but a savvy user can also program their own assembly code to run on it.

EMU8086 - MICROPROCESSOR EMULATOR primarily emulates the processor, not the other functions that a microcomputer running a 8086 processor would have. However, it still serves many of the same functions that an emulator for a more specific microcomputer might have, and more besides. For example, both the NEC-P9801 and early IBM-compatible computers used the 8086. Using EMU8086, one might be able to write assembly software that can run on either of those devices. On the flip side, EMU8086 can't access some of the more advanced hardware functionality that you might find in the monitors or other components of those devices.

Overall, EMU8086 - MICROPROCESSOR EMULATOR will be useful to computing enthusiasts and gearheads, and anyone who happens to work with this legacy processor even today: some computers, particularly in business and industrial applications, still use the 8086. Whether it's to tinker or to work, if you think you might want to emulate the 8086, start here.

The rows in the mix output histograms come in two flavors. The rows that begin with "*" are meta-categories which sum up the data in different ways. Here are descriptions of some of the meta categories:*scalar-simd anything with the XED_ATTRIBUTE_SIMD_SCALAR including AVX and SSE operations. The instructions that operate on one vector element and whose iclass name ends with "SS" or "SD" have this attribute.*sse-scalar any SSE instruction with the XED_ATTRIBUTE_SIMD_SCALAR*sse-packed any SSE instruction without the XED_ATTRIBUTE_SIMD_SCALAR*avx-scalar Any AVX instruction with the attribute XED_ATTRIBUTE_SIMD_SCALAR*avx128 Any AVX instruction with a 128b vector length but without the XED_ATTRIBUTE_SIMD_SCALAR*avx256 Any AVX instruction with a 256b vector length*avx512 Any AVX instruction with a 512b vector length.*mem-atomic Atomic memory operations*stack-read Stack reads*stack-write Stack writes*iprel-read IP-relative memory reads*iprel-write IP-relative memory writes*mem-read-1 Memory read, 1 byte*mem-read-2 Memory read, 2 bytes*mem-read-4 Memory read, 4 bytes*mem-read-8 Memory read, 8 bytes*mem-write-1 Memory write, 1 byte*mem-write-2 Memory write, 2 bytes*mem-write-4 Memory write, 4 bytes*mem-write-8 Memory write, 8 bytes*isa-ext-BASE The "BASE" ISA-extension (generic group of instructions. Base includes much of the older instructions*isa-ext-LONGMODE The set of instructions added with Intel64. These may be 32b or 64b instructions*isa-set-I186 ISA "set" is a categorization of instructions in the BASE ISA-extension.

To download the debugger tools for previous versions of Windows, you need to download the Windows SDK for the version you are debugging from theWindows SDK and emulator archive. In the installation wizard of the SDK, select Debugging Tools for Windows, and deselect all other components.

See the Sourceforge download page for the last released version including source and binary packages for Linux - amd64, Microsoft Windows - x86, Microsoft Windows - amd64 and Mac OS X - ppc and amd64.

Major Linux distributions take care of SDCC installation packages themselves and you will find SDCC in their repositories. Unfortunately SDCC packages included in Linux disributions are often outdated. In this case users are encouraged to compile the latest official SDCC release or a recent snapshot build by themselves or download the pre-compiled binaries from Sourceforge download page. 2b1af7f3a8
