SPARC(Scalable Processor Architecture) Sun Microsystems's specific CPU.

SPARC is a RISC instruction set architecture (ISA) developed by Sun Microsystems (now merged into Oracle), introduced in mid-1987.

SPARC hardware often runs Solaris, the Unix operating system, but other OSes run on SPARC hardware, and runs on more than just SPARC hardware.

SPARC doesn't allow unaligned loads, so SIGBUS (bus error) faults are a common problem when porting C or C++ to SPARC from x86 (for example).

In assembly, SPARC's 32 architectural registers are a sliding window onto a virtual register file. The save instruction that slides the window might or might not spill to memory, depending on whether the CPU microarchitecture is out of registers when it runs.

Does SPARC v9 have a double word compare and swap instruction?

So; on a 64 bit SPARC CPU which is v9 compliant, there exists I know a cas instruction. This operates on single word length values. I've also seen on the web reference to a casx instruction - but I can't find out anything much more about it. I'm…

How to set Solaris SPARC to run in little endian mode?

Is there a way to set Solaris running on SPARC to run on little endian mode? I've been reading that the v9 architecture chip is a bi-endian chip, though by default, the system runs in big endian. How to switch it to little endian? Thank you!

Check if installed version of JRE is 64 bit on solaris Sparc

Is there a clear or easy way to check over the command line if the installed JRE is 64 bit on a Sparc machine? I am used to seeing this in: java -version however it appears that Solaris only says what version and build of java is installed.

How to calculate division remainder in SPARC Assembly?

Here is the pseudo code which computes division of two positive integers. HR register saves remainder, and LR saves dividend. (and eventually saves root) However I think this algorithm has some problem. Because this algorithm sometimes don't…
