3.2
The core has two data spaces. The data spaces can be
considered either separate (for some DSP instruc-
tions), 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 3-7
and Y data spaces are accessed for MCU and DSP
instructions.
