Abstract
Abstract A buffer for storing data words consisting of several storage locations together with circuitry providing a first indicator that designates the next storage location to be stored into, a second indicator designating the next storage location to be retrieved from, and circuitry that provides the number of locations available for storage and the number of locations available for retrieval. The buffer includes the capability to store and retrieve several data words simultaneously.

Claim 1
Independent Claim
85 words
A digital data buffer storage system including a buffer store having a plurality of storage locations, means providing a first indicator designating the next storage location available to be written into, means providing a second indicator designating the next location to be read from, and means coupled to the buffer store, said first means and said second means, for controlling simultaneous read from or write to a plurality of storage locations available for said read or write as defined by the first and second indicators.
Claim 2
Dependent Claim
85 words
A digital data buffer storage system including a buffer store having a plurality of storage locations, means providing a first indicator designating the next storage location available to be written into, means providing a second indicator designating the next location to be read from, and means coupled to the buffer store, said first means and said second means, for controlling simultaneous read from or write to a plurality of storage locations available for said read or write as defined by the first and second indicators.
Claim 3
Dependent Claim
26 words
A storage system according to claim 1 in which the number of said available storage locations is less than the storage locations in the buffer store.
Claim 4
