5202830 ABSTRACT A memory unit having a multiplicity of storage locations for the temporary storage of series of groups of data signals. when the data groups are being stored in a memory location, index signals are developed that not only identify the location of the stored signal group, but when applied to the memory unit cause the data group to be withdrawn from the memory unit. The memory unit is comprised of a first addressable multiplicity of storage locations; a second addressable multiplicity of storage locations, the contents of the second multiplicity of storage locations adapted for addressing the first multiplicity of storage locations, a counter for addressing the second multiplicity of storage locations; and control logic for controlling the counter and entry and withdrawal of data signals in the first and second multiplicity of storage locations. The second multiplicity of storage locations contain the index signals that are also the addresses of the related data signal groups in the first multiplicity of storage locations. As data signal groups are withdrawn from a first storage location in response to application of index signals, a second storage location stores the address (i.e., the index signal of the first storage location not available for storage of a data signal group). The storage of a data signal group with the concurrent development of index signals, or the withdrawal of the data signal groups can be accomplished in one clock cycle. In addition, a simultaneous storage and withdrawal of data signal groups can be accomplished in one system clock cycle.
