34,359,738,368 bits (4 gibibytes) – maximum addressable memory for the Motorola 68020 (1984) and Intel 80386 (1985), also the volume size limit for the FAT16B file system (with 64 KiB clusters) as well as the maximum file size (4 GiB-1) in MS-DOS 7.1-8.0. 3.76 × 10 10 bits (4.7 gigabytes) – capacity of a single-layer, single-sided DVD: 2 36
The element pc requires ten blocks of memory of the size of pointer to char (usually 40 or 80 bytes on common platforms), but element pa is only one pointer (size 4 or 8 bytes), and the data it refers to is an array of ten bytes (sizeof * pa == 10).
Unsigned: From 0 to 15, which equals 2 4 − 1 1.2 8 byte, octet, i8, u8 Signed: From −128 to 127, from −(2 7) to 2 7 − 1 2.11 ASCII characters, code units in the UTF-8 character encoding: int8_t, signed char [b] sbyte: Shortint: byte: tinyint: INTEGER [c] byte: i8: Unsigned: From 0 to 255, which equals 2 8 − 1 2.41 uint8_t, unsigned ...
As a side benefit to this, an additional 512 MB of GDDR5 was available for developers to use for games adding up to 5.5 GB, as opposed to the 5 GB available on base PS4 hardware. GDDR5 memory speed was increased from 5.5 Gbit/s (or 4× 1.375 GHz) to 6.8 Gbit/s (or 4× 1.7 GHz), increasing total memory bandwidth to 217.6 GB/s which correlates to ...
The byte, 8 bits, 2 nibbles, is possibly the most commonly known and used base unit to describe data size. The word is a size that varies by and has a special importance for a particular hardware context. On modern hardware, a word is typically 2, 4 or 8 bytes, but the size varies dramatically on older hardware.
GVE uses a single byte as a header for 4 variable-length uint32 values. The header byte has 4 2-bit numbers representing the storage length of each of the following 4 uint32s. Such a layout eliminates the need to check and remove VLQ continuation bits. Data bytes can be copied directly to their destination.
For example, the Data General Nova minicomputer, and the Texas Instruments TMS9900 and National Semiconductor IMP-16 microcomputers used 16 bit words, and there were many 36-bit mainframe computers (e.g., PDP-10) which used 18-bit word addressing, not byte addressing, giving an address space of 2 18 36-bit words, approximately 1 megabyte of ...
In both cases, the LSb and MSb correlate directly to the least significant digit and most significant digit of a decimal integer. Bit indexing correlates to the positional notation of the value in base 2. For this reason, bit index is not affected by how the value is stored on the device, such as the value's byte order. Rather, it is a property ...
