Abstract
Centralized registers in which commands can be written are provided in correspondence with a plurality of control modules. Centralized registers for managing the pre-emption status of control modules and their tree-configuration hierarchical relations are also provided in correspondence with a plurality of control modules. Control modules to which a command should be transmitted are specified by looking up the registers that manage the pre-emption status and the tree-configuration hierarchical relations. When control modules have been specified, the latched command is written to the registers in which commands can be written.
Claims6
A control system, comprising:
- a plurality of control modules connected in a hierarchical tree configuration with each control module having an identity associated with a level within the hierarchical tree configuration;
- and
- a command transmission mechanism configured to transmit commands to the control modules, the command transmission mechanism including,
- a command write register group having a plurality of command write registers that correspond to the control modules and are capable of being written to,
- a write control mechanism to write commands in the command write register group in accordance with the hierarchical level of the control modules, and
- a matrix controller to provide the identity of the control modules, based on their hierarchical level, by turning on or off intersections of a switch matrix,
- wherein the write control mechanism writes commands in the command write register group in accordance with write command signals that arrive via the switch matrix intersections, and
- wherein the switch matrix is configured with signal lines that correspond to the control modules and is capable of providing a write command signal for a hierarchically lower level control module based on a feed-back of write command signal corresponding to a hierarchically higher level control module.
