22 Απρ 2020 · This compresses a full timestamp (8 bytes = 64 bits) down to just a single bit (64x compression). (In practice we can do even better by also applying Simple-8b + RLE. More below.) In other words, delta-encoding stores the first derivative of the dataset, while delta-of-delta encoding stores the second derivative of the dataset. Simple-8b
17 Ιουλ 2020 · Aligned access is faster because the external bus to memory is not a single byte wide - it is typically 4 or 8 bytes wide (or even wider). This means that the CPU doesn't fetch a single byte at a time - it fetches 4 or 8 bytes starting at the requested address.
2 ημέρες πριν · A group of eight bits is known as a Byte. 1 Byte can represent numbers between zero (00000000) and 255 (11111111), or 2 8 = 256 distinct positions. Of course, these bytes may also be combined to represent larger numbers.
29 Ιουλ 2021 · In plain language, time-series data is a dataset that tracks a sample over time and is collected regularly. Examples are commodity price, stock price, house price over time, weather records, company sales data, and patient health metrics like ECG.
A letter is usually stored using a single byte (8 bits). Each letter is assigned an integer number and that number is stored. For example, the letter `A' is the number 65, which looks like this in binary format: 01000001. The text “hello” (104, 101, 108, 108, 111) would look like this: 01101000 01100101 01101100 01101100 01101111
27 Σεπ 2021 · In this paper, we present TSXor, a simple yet effective lossless compressor for time series. The main idea is to exploit the redundancy/similarity between close-in-time values through a window...
19 Ιαν 2024 · In most computer systems, bytes serve as the base unit of data storage in memory. Each byte is made up of 8 bits, which can be individually set to 0 or 1, enabling versatile data representation. Memory is structured as a collection of addressable cells, each capable of storing a single byte.
