Abstract:
A method for allocating pages of a first and a second memory subsystem to pages of a frame buffer memory, wherein said frame buffer memory is comprised of N banks of memory with index 0 to N-1, and where each bank is further comprised of M pages, each page having a first data memory location address defining a starting page boundary, the method comprising the steps of:a) aligning the first data memory location of a first page of said first memory subsystem to page X of the frame buffer where 0<X<M*N, and where page X is located in a first memory bank;b) aligning all subsequent pages of said first memory subsystem to consecutive contiguous frame buffer pages of the frame buffer;c) aligning the first data memory location of a first page of said second memory subsystem to a memory bank other than the first memory bank;d) aligning all subsequent pages of said second memory subsystem to consecutive frame buffer pages of the frame buffer.
