Preliminary
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 X data space is used by all instructions and sup-
ports all addressing modes. There are separate read
and write data buses. The X read data bus is the return
data path for all instructions that view data space as
combined X and Y address space. It is also the X
address space data path for the dual operand read
instructions (MAC class). The X write data bus is the
only write path to data space for all instructions.
The X data space also supports Modulo Addressing for
all instructions, subject to Addressing mode restric-
tions. Bit-Reversed Addressing is only supported for
writes to X data space.
The Y data space is used in concert with the X data
space by the MAC class of instructions (CLR, ED,
EDAC, MAC, MOVSAC, MPY, MPY.N and MSC) to pro-
vide two concurrent data read paths. No writes occur
across the Y bus. This class of instructions dedicates
two W register pointers, W10 and W11, to always
address Y data space, independent of X data space,
whereas W8 and W9 always address X data space.
Note that during accumulator write back, the data
address space is considered a combination of X and Y
data spaces, so the write occurs across the X bus.
Consequently, the write can be to any address in the
entire data space.
The Y data space can only be used for the data pre-
fetch operation associated with the MAC class of
instructions. It also supports Modulo Addressing for
automated circular buffers. Of course, all other instruc-
tions can access the Y data address space through the
X data path, as part of the composite linear space.
The boundary between the X and Y data spaces is
defined as shown in Figure 3-8 and is not user pro-
grammable. Should an EA point to data outside its own
assigned address space, or to a location outside phys-
ical memory, an all-zero word/byte will be returned. For
example, although Y address space is visible by all
non-MAC instructions using any Addressing mode, an
attempt by a MAC instruction to fetch data from that
space, using W8 or W9 (X space pointers), will return
0x0000.
