Definition of lfsr in English English dictionary

linear feedback shift register

linear feedback shift register Used in many keystream generators because of its ability to produce sequences with certain desirable properties

Linear Feedback Shift Register Linear Feedback Shift Register (LFSR) A shift register where the input bit is driven by a linear function of the overall shift register value The initial value of the LFSR is called the seed, and the sequence of values is completely determined by it Most often the linear function is an XOR of the values of several bit positions Carefully chosen functions can result in an LFSR with maximal sequence length, specifically that an LFSR with a non-zero initial value will deterministically cycle through all possible shift register values (except zero) and return to its original value Low-Voltage Differential Signaling Electrical standard for communicating one bit via two conductors with small opposing voltage swings, used for ~1Gbps data transmission Notable standards include SPI-4 2, HyperTransport, RapidIO, SFI-4, XSBI

Acronym: Linear Feedback Shift Register LFSRs are shift registers with exclusive-OR gates that allow some bits in the register (usually referred to as a polynomial) to feed back into selected points within the register LFSRs are often used in BISTed designs to form PRPGs and MISRs

A shift register formed by D flip-flops and EXOR gates, chained together, with a synchronous clock, used either as input pattern generator or as signature analyzer (SER*)
