Detailed Description

template<size_t X, size_t Y>
class gem5::MatStore< X, Y >

Backing store for matrices.

This class provides the backing store for matricies, and is largely a wrapper around an std::array of bytes. This class provides some basic interfaces for assignment (copy the backing store) and comparison, and provides the interface for generating views onto the backing store. It is these views that are intended to be used by the end-user of the matrix in most cases.

This class is also responsible for handling the serialisation/unserialisation of matrix registers (see ShowParam and ParseParam).

Template Parameters

X	X size in bytes (number of columns).
Y	Y size in bytes (number of rows).
