The 64K bytes of internal data RAM are organized as two blocks of 32K bytes
located from address 8000 0000h to 8000 7FFFh and 8000 8000h to
8000 FFFFh. Side A and side B of the CPU or the DMA Controller can simulta-
neously access any portion of the internal data memory without conflict, when
using different blocks. Therefore, you do not have to consider the address
within a block if simultaneous accesses occur to different blocks. Accesses to
different blocks never cause performance penalties. You only have to pay
attention to the address when the two accesses occur in different blocks. Both
blocks are organized as eight 2K banks of 16-bit halfwords. Both the CPU and
DMA controller can still simultaneously access data that resides in different
banks within the same block without performance penalty. To avoid perfor-
mance penalties, you have to pay attention to address LSBs when two ac-
cesses involve data in the same block. This organization also allows the two
CPU data ports, A and B, to simultaneously access neighboring 16-bit data
elements inside the same block without a resource conflict.
