![]() But that space all fits in the instruction cache, so it's no execution penalty. jump-immediate)), so the software version does tend to take up a fair amount of space. ARM Thumb), or within an ISA (an instruction with a full-bus-width parameter e.g. RISC tends to be a bit verbose on instruction length (preferring fixed length encodings at full bus width, and obviously there are many exceptions, on the ISA level (e.g. It's like having a very brief library built into the hardware. In essence, you've shifted some user-space software into the "BIOS", except not even that, it's a deeper level, inside the CPU itself. I mean, that's all the 8086 is doing, via microcode. An example piece of RISC-V (RV32I) assembly code for a block copy of N 'words' looks like (do not hesitate to provide more optimized code if there is): * A DMA controller could be used instead, but it fits different needs IMO, would have extra setup overhead. * They could be made interruptible, but it would make the CPU design more complex. * Block copy instructions would typically be non-interruptible, possibly taking MANY cycles and thus "blocking" the CPU, which could cause issues with interrupt latency and just thread scheduling. Fusing instructions, super-scalar execution, and such, is not trivial though. * On RISC processors, it may make more sense to "fuse" simpler instructions than implement such "complex" instructions. Random thoughts about that: * As a "complex" kind of instructions, they may be more a CISC thing than a RISC thing. (We can also refer to the other thread dealing with strcpy() and memcpy() for instance.) Some CPUs implement block copy instructions (such as Intel x86 processors), others do not. Memory block copy is a *very* common operation in typical programs. Below is a list of the information on each tab of the event details page and whether or not it will be copied.Just having this thought lately, about potential benefits (or lack thereof) of block copy instructions in a CPU. Your calendar will remain on the time frame you had been viewing.Īs stated above, some event details will automatically be copied, and some will never be copied. ![]() ![]() If you are copying from the calendar, you will see a confirmation message.If you are copying from the event details page, you will be directed to the new event's details page.Once you have updated all information, click Save.The availability of each space will be updated as well (for more information about what the color of the status chips means, please see Conflict Checking). If the descriptions have been customized to describe what is happening in each booked space and that information is relevant to the copied event, do not check this box.The description field will appear and will default to the name you entered in step one. If the description on the original event's booked spaces is the event name or a generic description, check Override Booked Space Description.By default, the booked space descriptions on the copied event will match the descriptions on the original event.Any items which were removed from your inventory or any items in categories which were made inactive will not be copied.In order to copy instructions and item allocations, you must copy functions as well.If the event doesn't have certain details, those options cannot be selected. If you don't wish to copy a certain detail, click the X on its chip to remove it. Any details the event has will be automatically selected. Select which event details you would like to copy.We recommend each event have a unique name - maybe include the the year in the name, for example "FizzCon 2023". Once you've accessed the Copy Event slider: In either place, click on the more_vert more info menu and select Copy Event. You may copy an event from the event details page or from the summary slider on the calendar.
