In computing, octuple precision is a binary floating-point-based computer number format that occupies 32 bytes (256 bits) in computer memory. This 256-bit octuple precision is for applications requiring results in higher than quadruple precision. The range greatly exceeds what is needed to describe all known physical limitations within the ...
SHA-256 hash function. Smart contracts use 256- or 257-bit integers; 256-bit words for the Ethereum Virtual Machine. "We realize that a 257 bits byte is quite unusual, but for smart contracts it is ok to have at least 256 bits numbers. The leading VM for smart contracts, Ethereum VM, introduced this practice and other blockchain VMs followed." [8]
Lossy audio compression algorithms provide higher compression and are used in numerous audio applications including Vorbis and MP3. These algorithms almost all rely on psychoacoustics to eliminate or reduce fidelity of less audible sounds, thereby reducing the space required to store or transmit them.
24-bit and 32-bit audio does not require dithering, as the noise level of the digital converter is always louder than the required level of any dither that might be applied. 24-bit audio could theoretically encode 144 dB of dynamic range, and 32-bit audio can achieve 192 dB, but this is almost impossible to achieve in the real world, as even ...
8,192 bits (1,024 bytes) – RAM capacity of a ZX81 and a ZX80. 9,408 bits (1,176 bytes) – uncompressed single-channel frame length in standard MPEG audio (75 frames per second and per channel), with standard 16-bit sampling at 44,100 Hz 10 4: 15,360 bits – one screen of data displayed on an 8-bit monochrome text console (80x24) 2 14
Advanced Audio Coding (AAC) is an audio coding standard for lossy digital audio compression.It was designed to be the successor of the MP3 format and generally achieves higher sound quality than MP3 at the same bit rate.
Microsoft Teams uses AVX2 instructions to create a blurred or custom background behind video chat participants, [60] and for background noise suppression. [61] Pale Moon custom Windows builds greatly increase browsing speed due to the use of AVX2. simdjson, a JSON parsing library, uses AVX2 and AVX-512 to achieve improved decoding speed. [62] [63]
The zero-page, the first 256 bytes of memory that were used as pseudo-registers, could now be moved to any page in main memory using the B(ase page) register. The stack register was widened from 8 to 16-bits using a similar page register, SPH (stack pointer high), allowing the stack to be moved out of page one and to grow to larger sizes.
