First Claim
Patent Images
1. An electronic apparatus suitable for constituting a wideband server, in particular for transmitting music or images, comprising in combination:
- a main processor possessing a direct memory access channel;
a large capacity mass memory of the hard disk type, connected to said direct memory access channel; and
a plurality of outlet units, operatively connected to said direct memory access channel and each possessing two buffer memories of equal capacity and an auxiliary processor operatively connected thereto, said buffer memories being dual-access memories operatively connected to said direct memory access channel and operated in alternating mode by said auxiliary processor to empty said buffer memories in alternation without discontinuity with one of said two buffer memories being read from while the other of said two buffer memories is simultaneously filled at high speed with new data from said large capacity mass memory.

Abstract
A wideband server is defined by a main processor (10) communicating over a DMA channel (15) with a hard disk (16) and also with outlet cards (2-1 to 2-16). Each outlet card has its own processor which controls alternating mode to-processor access to two buffer memories A and B. While one of the buffer memories is delivering musical data to a user, the other is being filled, and vice versa.

14. An electronic apparatus, comprising:
-
a main processor; a direct memory access channel for wideband transmission of data; a high-speed large capacity mass memory connected to said direct memory access channel; and a plurality of outlet units for receiving the wideband transmission of data via said direct memory access channel, each of said outlet units including at least two dual-access buffer memories, each operatively connected to said direct memory access channel; and an auxiliary processor for controlling access to said dual-access buffer memories so that one of said dual-access buffer memories is receiving data from said direct memory access channel while another of said dual-access buffer memories is inputting data, thereby enabling wideband transmission of data without discontinuity.
