Abstract

A system and method for multi-channel data management with dynamically configurable routing, having multiple independent container instances or crossbars. The system and method provide dynamically allocated and released half- and full-duplex data communications channels through crossbar access ports, with intercommunications between transmit ports and receive ports being independently configured. Transmission and reception of data is provided through the reserving of pages of transmission media, allocation of pages to producers of data, transmission of the filled pages to a queue for reception at one or more receiving ports, and reception by a consumer through a receiving port. Allocation, transmission and reception of the pages may optionally be executed synchronous to the availability of the page. Page state changes are used to mark pages as to their availability, allocation, and queuing such that data transfer is accomplished using an in-place method.

Dependent claims

A system for managing paged data with crossbar containers and for communicating data from a produce of data to consumers of data in a software processing system, comprising:

one or more software processor means, said software processor means having a data bus for communicating data to and from the software processor means;
one or more data memory means communicably interconnected to said software processor means via said data bus;
one or more data pages disposed in said data memory means, accessible by software being processed by said software processor means;
one or more data ports defined in said data memory means;
one or more receivable page queues in said data memory means;
one or more receivable page synchronization means in said data memory means;
one or more locked page lists in said data memory means;
one or more available page queues in said data memory means;
one or more available page synchronization means in said data memory means;
a cross bar route matrix configuration means which dynamically manages route matrix definitions at said data ports, said crossbar route matrix configuration means functionally controllable by software being executed by said software processing means;
a crossbar page allocation means which allocates available data pages at said data ports with elective synchronization, and which modifies a state of said data pages from available to locked, and inserts said locked allocated data pages in locked lists, said allocation being performed under control by software being executed by said software processing means;
a crossbar page transmission means which transfers or copies said locked data pages to data ports determined by the route matrices, and which modifies the state of said transferred data pages to receivable, and inserts said transferred data pages in said receivable page queues;
and
a crossbar reception means which retrieves said data pages in said receivable page queues from selected data ports with elective synchronization, and modifies the state of said retrieved data pages to locked, and inserts said retrieved data pages in locked page lists, thereby completing a data communications path between the produce of the data and the consumers of the data.

11 more elements

A method for managing paged data with crossbar containers and for communicating data from a producer of data to consumers of data in a software processing system, comprising the steps of:

storing one or more data pages disposed in a data memory by the software processor;
defining one or more data ports in the data memory;
defining one or more receivable page queues in the data memory;
creating one or more locked page lists in the data memory;
creating one or more available page queues in the data memory;
configuring a crossbar route matrix under software control by the software processor, dynamically managing the crossbar route matrix definitions at said data ports;
allocating available data pages at said data ports by modifying a state of said available data pages from available to locked, inserting said locked allocated data pages in said locked page lists, said allocation being performed under control by software being executed by the software processor;
transmitting data pages by copying said locked allocated pages to said data ports determined by said crossbar route matrix, correspondingly modifying the state of said transmitted data pages to receivable, and inserting said transmitted data pages in said receivable page queues;
and
receiving data pages by retrieving said queued receivable data pages from said data ports selected by the software being executed by the software processor, and modifying the state of the received data pages to locked, and inserting the received data pages in locked lists, thereby completing the data communications path between the producer of the data and the consumers of the data.
