Claims
- 1. A method for storing data from an external central processor in a plurality of memory storage devices through a plurality of memory buffer devices, comprising the steps of:
- storing a first sequence of memory buffer identifiers in a first sequencing means;
- selecting a first plurality of memory buffer devices responsive to said first sequence of memory buffer identifiers from said first sequencing means to transfer data between said external processor and said first plurality of memory buffer devices;
- storing a second sequence of memory buffer identifiers in a second sequencing means; and
- selecting a second plurality of memory buffer devices responsive to said second sequence of memory buffer identifiers from said second sequencing means to transfer data between said external processor and said second plurality of memory buffer devices.
- 2. The method of claim 1 further comprising the step of accessing said first and second sequencing means in FIFO (first-in-first-out) fashion.
- 3. The method of claim 1 further comprising the steps of selectively providing one of a data bus and an output of said first sequencing means to an input of said first sequencing means.
- 4. The method of claim 1 wherein said selecting steps comprise applying said memory buffer identifiers to select inputs of said memory buffer devices.
- 5. The method of claim 1 wherein both of said selecting steps occur simultaneously.
- 6. The method of claim 1 wherein said selecting steps each cause the selection of different groups of said memory buffer devices.
- 7. A method for storing data from an external central processor in a plurality of memory storage devices through a plurality of buffer devices, comprising the steps of:
- storing a first sequence of memory buffer identifiers in a first sequencing means;
- selecting a first memory buffer device responsive to said first sequence of memory buffer identifiers from said first sequencing means to transfer data between said external processor and a first memory means in said first memory buffer device;
- initializing a first counter means with a first memory address from said first memory means;
- providing a first address data from said first counter means to said first memory means to transfer data between said first memory means and said memory storage devices;
- storing a second sequence of memory buffer identifiers in a second sequencing means;
- selecting a second memory buffer device responsive to said second sequence of memory buffer identifiers from said second sequencing means to transfer data between said external processor and a second memory means in said second memory buffer device;
- initializing a second counter means with a second memory address from said second memory means; and
- providing a second address data from said second counter means to said second memory means to transfer data between said second memory means and said memory storage devices.
- 8. The method according to claim 7 wherein a number of data bits per data word between said external processor and said first memory means differs from that of data bits per data word between said first memory means and said memory storage devices.
