Translator memory management system

A translator for translating messages between a first protocol and a second protocol, each message having a message size that is no larger than a maximum message size, the first protocol transporting message data with message envelopes having an envelope size that is no larger than a maximum envelope size, the translator comprising:

• a first protocol interface for interfacing with first protocol devices that communicate via the first protocol;
• a second protocol interface for interfacing with second protocol devices the communicate via the second protocol;
• and
• control logic coupling the first protocol interface and the second protocol interface;
• the first protocol interface having a first memory buffer pool for storing message data received from the control logic, the first memory buffer pool having a plurality of first buffers that each have a maximum size that is no larger than the sum of the maximum message size and additional header data,
• the first protocol interface also having a second memory buffer pool for storing message data to be transmitted to the control logic, the second memory buffer having a plurality of second buffers that each have a maximum size that is no larger than the sum of the maximum message size and additional header data.

A method of managing memory within a translator that translates messages between a first protocol and a second protocol, the translator further having a first protocol interface for interfacing with first protocol devices, a second protocol interface for interfacing with second protocol devices, and control logic for coupling the first and second interfaces, the first protocol transporting message data with message envelopes, the method comprising:

• determining the maximum size of any message that is translated by the translator;
• determining the maximum size of any message envelope to be utilized by the translator;
• forming, from the memory, a first plurality of memory buffers for storing message data received from the control logic, the first memory buffer having a maximum size that is no larger than the message size and additional header data;
• forming, from the memory, a second plurality of memory buffers for storing message data to be transmitted to the control logic, the second memory buffer having a maximum size that is no larger than the sum of maximum message size and additional header data.
