$3.<1\mathrm{.}0$ pt$>$ Consider a memcpy$(0$x$1000,0$x$2000,0$x$100)$ which copies one byte at a time from source to destination and given the following cache parameters:

$\backslash$Cache Parameters:

$\backslash --$ Block Size: $16$ bytes

$\backslash --256$ rows

$\backslash --4$ bits for the tag

$\backslash --$ Direct Mapped

$\backslash$Assume an empty cache to start

$3.$a$.(0\mathrm{.}5$ pts$)$ How many hits will occur when this memcpy is executed, consider both source and destination and for this question, make sure to consider how this would actually work, where the source byte is read and then teh destination byte is written.

$3.$b$.(0\mathrm{.}5$ pts$)$ If this cache were converted to $2-$way set associative, that would improve
