Hardware acceleration can slow down your computer if it is turned off. This is because the CPU needs to process all of the data. By turning it off, you can transfer some of this processing power to hardware that is specialized, such as sound cards and graphics cards, freeing up your processor for more tasks.
These devices are better in a specific task than your computer’s processor. Hardware accelerators can be used for a myriad of tasks like 3D rendering, video decoding and even regular expression hardware acceleration in the server industry to ward off spam attacks from using patterns such as ‘
Hardware acceleration can be used as an instrument for design to boost the performance of algorithms that are algorithmic and would normally take a general purpose CPU too long to complete. They can be built into chips, or external components that interact with processors by mapping instructions from the processor to hardware-accelerated functions. They can vary in granularity, from a single unit such as a memory block that handles bit blits, to a complete accelerator that runs fixed algorithms, like a motion estimation.
Cadence offers a full set of tools that support hardware acceleration design process. These include Stratus high-level synthesizing, Genus Logic Synthesis, Innovus implementation systems, low power analysis that conforms to the norm and Joules Power Analysis. These tools allow designers to design highly efficient and cost-effective hardware accelerators that are designed for their intended applications and market.
