Abstract
Abstract A high speed digital information storage system comprising means for providing n successive samples of serial data on n parallel paths coincident in time. Holding means are provided for holding the samples prior to storage. Storage means store the serial data samples and means are provided which skew and remultiplex the serial data at the output of the storage means when removed from the storage means. Clocking means provide clocking pulses to the holding means and the storage means in unison at one nth of the serial data rate.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
179 words
A high speed digital information storage system comprising: a. converter means for receiving successive samples of incoming serial data on a single path and for providing n successive samples of the serial data on n parallel paths coincident in time; b. holding means connected to said converter means for holding the n successive samples on said parallel paths for a period n times greater than the data repetition period to effectively reduce the data rate prior to storage; c. storage means connected to said holding means for storing the serial data held in said holding means; d. clocking means connected to said holding and storage means for clocking in unison said holding means and said storage means at one nth of the serial data rate; e. skewing means connected to said storage means for sequentially holding n coincident data samples on n parallel paths read out from the storage means; and f. remultiplexing means connected to said skewing means for receiving the n successive samples from the skewing means and for providing the successive samples on a single path.
Claim 2
Dependent Claim
179 words
A high speed digital information storage system comprising: a. converter means for receiving successive samples of incoming serial data on a single path and for providing n successive samples of the serial data on n parallel paths coincident in time; b. holding means connected to said converter means for holding the n successive samples on said parallel paths for a period n times greater than the data repetition period to effectively reduce the data rate prior to storage; c. storage means connected to said holding means for storing the serial data held in said holding means; d. clocking means connected to said holding and storage means for clocking in unison said holding means and said storage means at one nth of the serial data rate; e. skewing means connected to said storage means for sequentially holding n coincident data samples on n parallel paths read out from the storage means; and f. remultiplexing means connected to said skewing means for receiving the n successive samples from the skewing means and for providing the successive samples on a single path.
Claim 3
Dependent Claim
25 words
A storage system according to claim 1 wherein said converter means includes n - 1 series connected latches clocked at the incoming serial data rate.
Claim 4
Dependent Claim
93 words
A storage system according to claim 2 wherein said holding means comprises a parallel array of n latches each having a clocking input coupled to receive simultaneous clock pulses from said clocking means, the input of the first latch of said parallel array being connected to the output of the nth series connected latch of said converter means, the inputs of the succeeding parallel latches except the nth being connected respectively between the preceding series latches of said converter means, and the nth latch being connected to receive the incoming serial data directly.
Claim 5
Dependent Claim
28 words
A storage system according to claim 1 wherein said storage means comprises a plurality of stores each having n parallel paths consisting of identical lengths of shift registers.
Claim 6
Dependent Claim
29 words
A storage system according to claim 4, in which clocking means are provided for respectively enabling the inputs, writing in and reading out the data, and enabling the outputs.
Claim 7
Dependent Claim
59 words
A storage system according to claim 1 wherein said skewing means comprises n latches each on one of n parallel paths, which latches are clocked in sequence at one nth of the serial data rate and said remultiplexing means comprises a latch connected to the n skewing latches and clocked at a rate equal to the incoming data rate.
