US 10,320,389 B2 · Programmable shift register with programmable load location

Abstract

Programmable shift register with programmable load location (pSRL) for data storage and method thereof is disclosed. A loadable programmable Shift Register (pSR) according to present disclosure receives a programmable input LL that defines where data D is to be loaded from the Load Register when L (Load Control Signal)=1. The loadable Shift Register with programmable load location (pSRL) is configured to obtain L (Load Control Signal), S (Shift Control Signal), LL (Load Location Control Signal), and p (programmable shift value), and wherein the pSRL is adapted to perform loading and shifting of data D based at least on the L, S, LL, and p values.

Dependent claims

A loadable programmable Shift Register (pSR) comprising:

a cascade of flip flops, each flip flop in the cascade of flip flops having an input and an output;
and
a bit-remapper configured to receive data from a load register and load the data into the cascade of flip flops based on a plurality of control signals, the plurality of control signals comprising:
a programmable input load location that defines a position in the cascade of flip flops where the data is to be loaded from the load register;
a load control signal for controlling the loading of the data into the cascade of flip flops,
a shift control signal for controlling a shifting of contents of the cascade of flip flops, and
a programmable shift value indicating a number of bits to shift the contents of the cascade of flip flops responsive to the shift control signal.
