SeeĪxis Communications ETRAX 100LX embedded network CPU. List with more than two hundred machine types.ĪRM processors with 26 bit address space.Ītmel AVR32 is a 32-bit RISC microprocessor architecture. Machines based on one of the many types of ARM microprocessor (ARM, StrongARM, Xscale). (I think there has been a Windows NT for the DEC Alpha, but it has The Microsoft world is mostly tied to the i386 platform. Of it is written in C, so that porting to new hardware platforms (Multics was written in PL/I but required special hardware),Īnd the quick rise of Unix was greatly helped by the fact that most 1.3 Hardware platformsīefore Unix, most operating systems were written in assembler The goal: running most Unix software, was reached already in 0.99.Ībout half of the current source is I/O subsystem and device drivers.Ībout one-fifth is architecture-specific code. Roughly linear at about 60000 lines/month. The Linux kernel source grew superlinearly at first, then growth became Wanted the kernel simple, yet powerful enough to run most unix software. The guiding line when implementing linux was: get it working fast. Linus Torvalds, a student in Helsinki, started a small operating system Will support anything other than AT-harddisks, as that's all I have :-(. It is NOT protable (uses 386 task switching etc), and it probably never Linus Yes - it's free of any minix code, and it has a multi-threaded fs. Any suggestionsĪre welcome, but I won't promise I'll implement them :-) I'd like to know what features most people would want. This implies that I'll get something practical within a few months, and I've currently ported bash(1.08) and gcc(1.40), and things seem to work. (same physical layout of the file-system (due to practical reasons) Things people like/dislike in minix, as my OS resembles it somewhat Since april, and is starting to get ready. Professional like gnu) for 386(486) AT clones. I'm doing a (free) operating system (just a hobby, won't be big and Subject: What would you like to see most in minix? The source base of the kernel was developed from scratch, notĪs a continuation of original Bell Labs work.) There is a point where Linux differs from other Unices: Maybe the lawyer has doubts: who owns the trademark Unix today? (Is Linux a Unix system? That depends on your definition of Unix.įor the user there is no doubt: Linux is a Unix.
