Bandwidth efficient frame design

FFT techniques can be used to reduce the number of multiplications for an FIR filter -based time-domain equalizer to a number comparable with OFDM, at the cost of delay between reception and decoding which also becomes comparable with OFDM. If differential modulation such as DPSK or DQPSK is applied to each sub-carrier, equalization can be completely omitted, since these non-coherent schemes are insensitive to slowly changing amplitude and phase distortion. In a sense, improvements in FIR equalization using FFTs or partial FFTs leads mathematically closer to OFDM,[ citation needed ] but the OFDM technique is easier to understand and implement, and the sub-channels can be independently adapted in other ways than varying equalization coefficients, such as switching between different QAM constellation patterns and error-correction schemes to match individual sub-channel noise and interference characteristics.

One of the most bandwidth intensive use cases is video post processing. In many use cases, the GPU is required to read a video and apply effects when using video streams as textures in 2D or 3D scenes. Its lossless compression ratios are comparable with other leading standards but with the added benefit of fine grained random access, which importantly allows for the application of AFBC throughout other IP blocks within your SoC design.

Lossless compression format Format preserves original image exactly bit exact. Compression ratios comparable to other lossless compression standards. Licensable for integration with 3rd party media IP. Reduces SoC energy consumption Due to significant reduction in bandwidth.

Area efficient AFBC can be added at zero area cost. Bounded worst-case compression ratios Random access down to 4x4 block level. Exactly the same optimization will be applied to the output buffers intended for the screen. Whether it is the GPU or Video Processor producing the final frame buffers, they will be compressed so that the Display Processor will read these in the AFBC format and only uncompress when moving to the display memory.

The blue curve shows the bandwidth when AFBC is not used for reference. Bandwidth reductions are considerable. Reducing system memory bandwidth is of course, just one element of Arm's overall power reduction strategy — are many other things we do, both large and small, that lead to us having a low-power solution.
