FIGURE 3-5:
3.2
The core has two data spaces. The data spaces can be
considered
instructions), or as one unified linear address range (for
MCU instructions). The data spaces are accessed
using two Address Generation Units (AGUs) and
separate data paths.
3.2.1
The data space memory is split into two blocks, X and
Y data space. A key element of this architecture is that
Y space is a subset of X space, and is fully contained
within X space. In order to provide an apparent linear
addressing space, X and Y spaces have contiguous
addresses.

When executing any instruction other than one of the
MAC class of instructions, the X block consists of the
64 Kbyte data address space (including all Y
addresses). When executing one of the MAC class of
instructions, the X block consists of the 64 Kbyte data
address space excluding the Y address block (for data
reads only). In other words, all other instructions
regard the entire data memory as one composite
address space. The MAC class instructions extract the
Y address space from data space and address it using
EAs sourced from W10 and W11. The remaining X
data space is addressed using W8 and W9. Both
address spaces are concurrently accessed only with
the MAC class instructions.
A data space memory map is shown in Figure 3-6.
Figure 3-7 shows a graphical summary of how X and Y
data spaces are accessed for MCU and DSP
instructions.
