	Register window - Wikipedia, the free encyclopedia
		In computer engineering, the use of register windows is a technique to improve the performance of a particularly common operation, the procedure call.
		Registers are used by the CPU in order to hold temporary values while working on longer strings of instructions.
		Eight registers (L0 through L7) are local to the current procedure level, and eight registers (o0 through o7) are the outputs from the current procedure level to the next level called.

		The Window Invalid Mask (wim) and the Current Window Pointer (cwp) field in the psr are used in conjunction to manage the finite set of register windows and detect the window overflow and underflow conditions.
		The output registers for register window N are the same as the input registers for register window ((N - 1) modulo RW) where RW is the number of register windows.
		When a register window is allocated, the new set of local registers are available for the exclusive use of the subroutine which allocated this register set.

	Register Window Instructions (Site not responding. Last check: 2007-10-18)
		The SAVE instruction rotates the register window forward one frame, renaming the out registers from the old window to be the in registers for the new, the out and local registers become effectively new registers.
		The RESTORE instruction rotates the rotates the register window backward one frame, renaming the in registers from the old window to be the out registers for the new.
		If a spill or fill trap is not generated by the instructions, they behave like an ADD instruction, using rs1 and rs2 registers as named in the old window, and rd as named in the new window for the source and destination registers.

	11 Register Windows (Site not responding. Last check: 2007-10-18)
		The input registers are overlapped with the caller's output registers.
		The instruction used to restore the caller's register window is usually put in the branch delay slot of the instruction used to return control to the caller.
		Because the caller's register window has not been restored when the called procedure issues the return instruction, the return instruction needs to use %i7 in calculating the return address instead of %o7 (%r15).

		For instance, a source window will have an options menu item to control the display of line numbers, but a register window will instead have an option to choose the radix in which to display register contents.
		Registers that have changed since the last evaluation of the register contents are highlighted in red.
		This window may be activated either by double-clicking on a highlighted phrase in the source window (which will import that phrase as a new expression), or by calling it up via the Window menu.

		"Register windows" allow a stack of registers to parallel the stack in main memory:
		Memory stack needs to be coordinated with register windows, i.e., push an activation record onto memory stack exactly when you push a new register window, similarly coordinate pops.
		This pushes a window, thus getting a new sp and making old one become fp, and make new sp point to a frame's worth of memory beyond where old sp pointed.

	Bits and pieces : Weblog
		When SPARC ISA was first designed, the register window feature made sense given the first implementation characteristics such as unified cache and relatively shallow call depth.
		The register window makes the call stack trace explicit, straightfoward and transparent, thus makes it fairly simple to do a stack unwind and do some tricks in the exception handling code.
		Because of the register window and non-executable stack, it is quite a bit more difficult to exploit the buffer overflow vulnerability on SPARC, although it doesn't make exploiting impossible.

		If the window is large enough, you can see that the command jal InputUnsigned is in the IF stage and the preceding command addi r1, r0, 0x1000 is in the second stage, ID. The other blocks are marked with a cross, showing that no sensible information is processed in them.
		When examining the code by opening the code window (double click on icon code if it is not already opened) you will notice that the next instructions are all nearly the same; they are sw-operations that store words from a register into the memory.
		By re-examining the statistics window, you learn that the number of Control stalls and Trap stalls remained the same, but the number of RAW stalls was now 53 instead of 17, thus increasing the total number of simulation cycles to 236.

	How Quantify times register-window traps Rational Quantify (Site not responding. Last check: 2007-10-18)
		The SPARC architecture provides a fixed set of register windows that are allocated for each function call, providing very fast access to function arguments and local variables.
		When the set of register windows is exhausted, however, the hardware issues a trap to the operating system to save and later restore the contents of a window to memory.
		By simulating the register-window mechanism, Quantify records the time spent by the operating system in preserving and restoring register windows required by your program.

		Put another way, main's o0 register (for example) is the same register as i0 for a subroutine called from main.
		The cool thing about it is that the previous register window's sp becomes the new register window's fp.

	Window of exposure lets viruses run rampant \| The Register
		It’s long been known that there is a ‘window of exposure’ - the interval between when a virus begins spreading and signature updates are issued by anti-virus vendors.
		BlackSpider has put a figure on this phenomenon in order to back up its argument that there’s a high risk of infection during this ‘window of exposure’ for firms that rely on conventional anti-virus scanners alone.
		Vendors that make most of their money from desktop or server-based anti-virus scanners argue that most of these viruses could be thwarted by a policy of blocking executable attachments in email.
