Hardware acceleration may slow down your computer when it is shut off. This is due to the CPU having to process all of the data. By turning it off, you can transfer some of the processing power to specific hardware such as graphics cards and sound cards, freeing your processor to perform other tasks.
This is because these devices were designed to perform a specific task and are superior in this area than your computer’s general purpose processor. Hardware accelerators can be used for a myriad of tasks, including 3D rendering, video decoding and even regular expression acceleration in the server industry to prevent spam attacks from using patterns such as ‘
Hardware acceleration is utilized as an instrument for design to improve the efficiency of algorithms that are algorithmic and would normally take a general-purpose CPU too long to complete. They can be integrated into a chip or external components that connect directly to the processor, mapping processor instructions to hardware accelerated functions. They can vary in granularity, from a single unit, like a memory block that handles bit blits, to an entire accelerator that runs a fixed algorithms, such as a motion estimation.
Cadence offers a comprehensive suite of tools that can be used to support every stage of the hardware acceleration design process, from Stratus high-level synthesizing and Genus logic to Innovus implementation system, conformal low-power analysis and Joules RTL power analysis. These tools allow designers to create highly efficient and cost-effective hardware accelerations that are designed for the intended applications and markets.
