I am trying to implement the axi outstanding feature in CPP, i tried to search if there is already a model in CPP, did not find alot. Is there such model ? If not, Is there any diff in terms of READ and WRITE when it comes to outstanding ?
In additional, what is the expectation to performance degregation when having memory latency 10 with oustatnding of 16 aginst memory with 200 as first access latency and the secong access latency is 1, assuming b2b transactions.
Hi, Thanks for you answer.
I will make it more clear, if we are haveing a memory with 200 cycle latency for the data and outstanding Q of 16, the read and the write will be symmetrical ? or the write will be shorter than the read ?
It depends on your system whether the read and write latency is symmetrical. Many systems allow posted writes to return an early write response which means the write latency is shorter than the read latency.
