4.2.3
Modulo Addressing can be applied to the Effective
Address (EA) calculation associated with any W
register. It is important to realize that the address
boundaries check for addresses less than, or greater
than the upper (for incrementing buffers), and lower (for
decrementing buffers) boundary addresses (not just
equal to). Address changes may, therefore, jump
beyond boundaries and still be adjusted correctly.
4.3
Bit-Reversed Addressing is intended to simplify data
re-ordering for radix-2 FFT algorithms. It is supported
by the X AGU for data writes only.
The modifier, which may be a constant value or register
contents, is regarded as having its bit order reversed. The
address source and destination are kept in normal order.
Thus, the only operand requiring reversal is the modifier.
4.3.1
Bit-Reversed Addressing is enabled when:
• BWM (W register selection) in the MODCON reg-
• The BREN bit is set in the XBREV register
• The addressing mode used is Register Indirect

be accessed using Bit-Reversed Addressing)

Bit-Reversed Addressing
MODULO ADDRESSING
APPLICABILITY
The modulo corrected Effective Address
is written back to the register only when
Pre-Modify or Post-Modify Addressing
mode is used to compute the EA. When
an address offset (e.g., [W7+W2]) is used,
Modulo address correction is performed,
but the contents of the register remain
unchanged.
BIT-REVERSED ADDRESSING
IMPLEMENTATION
If the length of a bit-reversed buffer is M = 2
then the last ‘N’ bits of the data buffer Start address
must be zeros.
XB<14:0> is the bit-reversed address modifier or ‘pivot
point’ which is typically a constant. In the case of an
FFT computation, its value is equal to half of the FFT
data buffer size.
When enabled, Bit-Reversed Addressing is only
executed for register indirect with pre-increment or
post-increment addressing and word-sized data writes.
It does not function for any other addressing mode or
for byte-sized data. Normal addresses are generated
instead. When Bit-Reversed Addressing is active, the
W address pointer is always added to the address
modifier (XB) and the offset associated with the
Register Indirect Addressing mode is ignored. In
addition, as word-sized data is a requirement, the LSb
of the EA is ignored (and always clear).
If Bit-Reversed Addressing has already been enabled
by setting the BREN bit (XBREV<15>), then a write to
the XBREV register should not be immediately followed
by an indirect read operation using the W register that
has been designated as the bit-reversed pointer.
Note:
Note:
All bit-reversed EA calculations assume
word-sized data (LSb of every EA is
always clear). The XB value is scaled
accordingly to generate compatible (byte)
addresses.
Modulo Addressing and Bit-Reversed
Addressing
together. In the event that the user
attempts to do this, Bit-Reversed Address-
ing assumes priority when active for the X
WAGU, and X WAGU Modulo Addressing
is disabled. However, Modulo Addressing
continues to function in the X RAGU.
