bit field

bit field

(data)
Part of an item of data, storage location or message, identified as a certain number of contiguous bits starting at a certain bit position within the data. Bit position zero is usually the least significant bit.

For example, in an ARM machine code instruction the four-bit field at bits 28 to 31 (the four most significant bits in the 32-bit word) is the "condition code".

Step 4: Row of bit field giving after conversion to decimal system lowest value gives the system, in which one step of online identification is proceeded.
For instance, a typical "spin-valve" read sensor, in response to a 250 ps pulsed field from a magnetic bit, will ring for approximately 2 ns after the applied bit field. Similarly, when an MRAM element is switched, the magnetic energy will cause the element to oscillate or break up into a disordered high-temperature magnetic state.
