The current era of SIMD processors grew out of the desktop-computer market rather than the supercomputer market. As desktop processors became powerful enough to support real-time gaming and audio/video processing during the 1990s, demand grew for this particular type of computing power, and microprocessor vendors turned to SIMD to meet the ...
For instance, to handle an IF-ELSE block where various threads of a processor execute different paths, all threads must actually process both paths (as all threads of a processor always execute in lock-step), but masking is used to disable and enable the various threads as appropriate. Masking is avoided when control flow is coherent for the ...
The Intel Core & Core 2 processor lines (2006) that succeeded the Pentium 4 model line didn't utilize hyper-threading. The processors based on the Core microarchitecture did not have hyper-threading because the Core microarchitecture was a descendant of the older P6 microarchitecture .
As other resources are also shared, processor affinity alone cannot be used as the basis for CPU dispatching. If a process has recently run on one virtual hyper-threaded CPU in a given core, and that virtual CPU is currently busy but its partner CPU is not, cache affinity would suggest that the process should be dispatched to the idle partner CPU.
Its CPU cores are the first to be used in a Mac processor designed by Apple and the first to use the ARM instruction set architecture. It has 8 CPU cores (4 performance and 4 efficiency), up to 8 GPU cores, and a 16-core Neural Engine, as well as LPDDR4X memory with a bandwidth of 68 GB/s.

Because much of the Toolbox is implemented in ROM, alongside the computer's firmware, it was convenient to use as a bootloader environment. In conjunction with resources stored on the ROM chip, the Toolbox can turn the screen gray, show a dialog box with the signature "Welcome to Macintosh" greeting, and display the mouse cursor.
