Writing a 64 bit register via a 32 bit socket

[Khushi]

Hello

Do I need to call b-transport twice when writing a 64 bit register via a 32 bit socket?

Do a 32 bit socket can only read or write 32 bit or less at a time?

Thank you

The TLM payload carries a data as a byte array, along with length of data and optional byte-enables. An initiator can perform a 64-bit (or even more) transfers with a single `b_transport` call, by setting the length appropriately.

So - you may then ask, why is the socket width that is cooked into the type relevant? One reason is that the width is reflective of the data-width in real hardware, so could be used to calculate an annotated delay value (for example). Another place where it assumes importance if we have mixed-endian systems - the specification has a discussion on that.
