Accessing A Logic Device Through A Serial Interface

An apparatus for accessing a logic device through a serial interface, the apparatus comprising a computer processor, a computer memory operatively coupled to the computer processor, the computer memory having disposed within it computer program instructions that when executed by the computer processor cause the apparatus to carry out the steps of:

• receiving, by the serial interface of the logic device, a first data access request indicating a non-linear address mode, wherein the first data access request includes:
• a non-linear address corresponding a non-linear index specifying a plurality of non-linear addresses, the non-linear index associating each non-linear address with one of the plurality of registers;
• a data count indicating an amount of data to be accessed in the first data access request;
• and
• a page offset value indicating within a register, a starting page to perform the first data access request;
• identifying in the non-linear address mode, by the logic device, a location within the logic device based on the non-linear address and the starting page;
• and
• performing at the identified location, by the logic device, a serial transaction in accordance with the first data access request.

A computer program product for accessing a logic device through a serial interface, the computer program product disposed upon a computer readable medium, the computer program product comprising computer program instructions capable, when executed, of causing a computer to carry out the steps of:

• receiving, by the serial interface of the logic device, a first data access request indicating a non-linear address mode, wherein the first data access request includes:
• a non-linear address corresponding a non-linear index specifying a plurality of non-linear addresses, the non-linear index associating each non-linear address with one of the plurality of registers;
• a data count indicating an amount of data to be accessed in the first data access request;
• and
• a page offset value indicating within a register, a starting page to perform the first data access request;
• identifying in the non-linear address mode, by the logic device, a location within the logic device based on the non-linear address and the starting page;
• and
• performing at the identified location, by the logic device, a serial transaction in accordance with the first data access request.

A method of accessing a logic device through a serial interface, the logic device including a plurality of registers, the method comprising:

• transmitting to the serial interface of the logic device, by a processing device, a first data access request indicating a non-linear address mode, wherein the first data access request includes:
• a non-linear address corresponding to a non-linear index specifying a plurality of non-linear addresses, the non-linear index associating each non-linear address with one of the plurality of registers;
• a data count indicating an amount of data to be accessed in the first data access request;
• and
• a page offset value indicating within a register, a starting page to perform the first data access request;
• receiving from the serial interface of the logic device, by the processing device, an indication that the logic device performed the first data access request at a location identified by the non-linear address and the starting page.
