Dual-ported video RAM (VRAM) is a dual-ported RAM variant of dynamic RAM (DRAM), which was once commonly used to store the Framebuffer in Graphics card, Dual-ported RAM allows the CPU to read and write data to memory as if it were a conventional DRAM chip, while adding a second port that reads out data.
In September 2012, YouTube launched its first app for the iPhone, following the decision to drop YouTube as one of the preloaded apps in the iPhone 5 and iOS 6 operating system. [112] According to GlobalWebIndex , YouTube was used by 35% of smartphone users between April and June 2013, making it the third-most used app. [ 113 ]
Both the iPhone 8 and 8 Plus were supplied with iOS 11 on launch, [25] [27] and support iOS 12, iOS 13, iOS 14, iOS 15 and iOS 16. Apple announced that the iPhone 8 and 8 Plus, as well as the iPhone X, would not support iOS 17 due to hardware limitations. [35] However, the devices still receive security updates.
As with prior M series SoCs, this serves as both RAM and video RAM. The M3 has 8 memory controllers, the M3 Pro has 12 and the M3 Max has 32. Each controller is 16-bits wide and is capable of accessing up to 4 GiB of memory. [14] The M3 Pro and 14-core M3 Max have lower memory bandwidth than the M1/M2 Pro and M1/M2 Max respectively.
Graphics DDR SDRAM (GDDR SDRAM) is a type of synchronous dynamic random-access memory (SDRAM) specifically designed for applications requiring high bandwidth, [1] e.g. graphics processing units (GPUs).
The exact size of the video memory could be reconfigured by software to meet the needs of the current program. An early hybrid system was the Commodore Amiga which could run as a shared memory system, but would load executable code preferentially into non-shared " fast RAM " if it was available.
This file requires updating because: Update iPhone 13, 13 Mini, 13 Pro and Pro Max, iPhone SE 3rd, iPhone 14 and 14 Plus, 14 Pro and 14 Pro Max, iPhone 15 and 15 Plus, 15 Pro and 15 Pro Max, iPhone 16 and 16 Plus, 16 Pro and 16 Pro Max, Please. In doing so, you could add a timestamp to the file.
This used 4 bits per pixel, with a total memory use of (160 * 100 * 4) / 8 = 8 kilobytes. 320 × 200 in 4 colors, chosen from 3 fixed palettes, with high- and low-intensity variants, with color 1 chosen from a 16-color palette. This used 2 bits per pixel, with a total memory use of (320 * 200 * 2) / 8 = 16 kilobytes.
