so to get back to original question.Shutter has to be WAy faster Than 0,5 to capture sports an such..
The camera can do burst with 7 pics pr sec.
Know there will be memorycards and memoryhandling issues
Do you really think that DSP cant converting raw to jpg in "realtime" ??burst mode just fill the Free ram with 7 RAW of 30MB each (210MB approx)

I think it can be comressed from sensor with dsp hardware in real time , and debug function just "say" to dsp create raw file without compression. I say more . For axample ( its just examle) gopro 3+ can 4k capture with 15(?)fps . You think 8mp pictures " go to" ram in raw mode ? ) then compressed in movie )) ??I think they are keept here until je JPEG is fully transfered.
Image from sensor in raw ))) "Calculate similarity" h264 codec! and it is last stage of processing ... its after geting image from sensor , and after all image corrections ( and all this do dsp in real time )The way a video is made is not image by image to compress it has to calculate similarity between following ones and other stuffs.
DSP is just good at signal treatment. there is many I/O ops.
I dont say that dsp not needed in ram at all, but it neds not much like you think. And not in ram problem . Problem in dsp hardware, supported or not some modes. If a7 not supported 2.7k 60 we have not cameras with a7 and 2.7k 60 )) If a9 support 2.7k 60 we have gopro 4be ))DSP can work in realtime but in fact the data doest not follow this way : sensor > isp > SDCard ...chipset have failure too so you need to keep the datas in highspeed memory (RAM) at least the time they are processed to prevent failure. there is security manywhere and buffer are used to.
there is electronic interferences, error and else...you have to deal with it. realtime is more like unperceptible treatment by human capacity.
