Module based address translation arrangement and transaction offloading in a digital system

In a digital system including a plurality of modules for executing a data transaction using a bus arrangement which interconnects said modules, said data transaction including an address portion which defines a data portion, a method comprising the steps of:

• a) initiating the address portion of said data transaction on said bus arrangement using a first one of said modules;
• b) receiving the address portion of the transaction on the bus arrangement from the first module using a second module;
• and
• c) based on a set of criteria, performing said data portion using the second module or selectively generating a translated address portion such that the translated address portion identifies one of said modules, other than said first or second module and, thereafter, the second module sends the translated address portion to the identified one of the modules and the identified module then participates, using said translated address portion, in the execution of said data portion of the transaction with said first module.

In a digital system including a plurality of modules interconnected by a bus arrangement, a method comprising the steps of:

• a) initiating a data transaction using a first module by initiating an address portion on the bus arrangement associated with the data transaction, said address portion identifying a second module and defining a data portion;
• b) accepting the address portion using said second module;
• c) using the second module, originating a translated address portion on the bus arrangement using said second module based on a set of criteria, said translated address portion identifying a specific module, other than said first module;
• d) accepting the translated address portion using the specific module;
• and
• e) executing the data portion using said specific module and said first module.

In a digital system including a plurality of modules interconnected by a bus arrangement, a method comprising the steps of:

• a) initializing a data transaction using a first module by initiating an address portion on the bus arrangement associated with the data transaction, said address portion identifying a second module and defining a data portion;
• b) accepting the address portion with said second module;
• c) using the second module, selecting a particular module to participate in the execution of said data portion with said first module from a group of modules including said second module and one or more other modules based on a set of criteria;
• d) notifying said particular module in the form of a request to participate in said data portion with the first module;
• and
• e) executing the data portion using the particular module that is selected and the first module.

In a digital system including a plurality of modules interconnected by a bus arrangement and configured for performing a series of data transactions, a method comprising the steps of:

• a) generating a first transaction on the bus arrangement using a first module by initiating a first address portion associated with the first transaction, said first address portion identifying a second module and defining a first data transfer containing digital information;
• b) accepting the first address portion using said second module;
• c) selecting a particular module to participate in the execution of said first data transfer with said first module from the group of said second module and one or more other modules based on a set of criteria;
• d) notifying said particular module in the form of a request to participate in said first data transfer with the first module;
• and
• e) performing the first data transfer between the particular module that is selected and the first module such the digital information associated with the first data transfer is stored in the particular module.

In a digital system including at least three modules for executing a data transaction using a bus arrangement which interconnects said modules, said data transaction including an address portion which defines a data portion, a method comprising the steps of:

• configuring a first one of said modules for initiating the address portion of said data transaction on said bus arrangement;
• and
• arranging a second one of said modules to receive the address portion of the transaction on the bus arrangement from the first module;
• and
• using the second module, translating, based on a set of criteria, the address portion to a third module for participating in the execution of said data portion with said first module such that the first and third modules then participate in said data portion of the transaction exclusive of the second module.
