The ADSP-BF54x Blackfin processors’ DMA controllers sup-
port both 1-dimensional (1D) and 2-dimensional (2D) DMA
transfers. DMA transfer initialization can be implemented from
registers or from sets of parameters called descriptor blocks.
The 2D DMA capability supports arbitrary row and column
sizes up to 64K elements by 64K elements, and arbitrary row
and column step sizes up to ±32K elements. Furthermore, the
column step size can be less than the row step size, allowing
implementation of interleaved data streams. This feature is
especially useful in video applications where data can be de-
interleaved on the fly.
Examples of DMA types supported by the ADSP-BF54x
Blackfin processors’ DMA controllers include:
A single, linear buffer that stops upon completion
A circular, auto-refreshing buffer that interrupts on each
full or fractionally full buffer
1D or 2D DMA using a linked list of descriptors
2D DMA using an array of descriptors, specifying only the
base DMA address within a common page
In addition to the dedicated peripheral DMA channels, the
DMAC1 and DMAC0 controllers each feature two memory
DMA channel pairs for transfers between the various memories
of the ADSP-BF54x Blackfin processors. This enables transfers
of blocks of data between any of the memories—including
external DDR, ROM, SRAM, and flash memory—with minimal
processor intervention. Like peripheral DMAs, memory DMA
transfers can be controlled by a very flexible descriptor-based
methodology or by a standard register-based autobuffer
mechanism.
The memory DMA channels of the DMAC1 controller
(MDMA2 and MDMA3) can be controlled optionally by the
external DMA request input pins. When used in conjunction
with the External Bus Interface Unit (EBIU), this handshaked
memory DMA (HMDMA) scheme can be used to efficiently
exchange data with block-buffered or FIFO-style devices con-
nected externally. Users can select whether the DMA request
pins control the source or the destination side of the memory
DMA. It allows control of the number of data transfers for
memory DMA. The number of transfers per edge is program-
mable. This feature can be programmed to allow memory DMA
to have an increased priority on the external bus relative to the
core.
Host DMA Port Interface
The host DMA port (HOSTDP) facilitates a host device external
to the ADSP-BF54x Blackfin processors to be a DMA master
and transfer data back and forth. The host device always masters
the transactions, and the processor is always a DMA slave
device.
The HOSTDP is enabled through the peripheral access bus.
Once the port has been enabled, the transactions are controlled
by the external host. The external host programs standard DMA
configuration words in order to send/receive data to any valid
internal or external memory location. The host DMA port con-
troller includes the following features:
Allows an external master to configure DMA read/write
data transfers and read port status
Uses a flexible asynchronous memory protocol for its
external interface
Allows an 8- or 16-bit external data interface to the host
device
Supports half-duplex operation
Supports little/big endian data transfers
Acknowledge mode allows flow control on host
transactions
Interrupt mode guarantees a burst of FIFO depth host
transactions
REAL-TIME CLOCK
The ADSP-BF54x Blackfin processors’ real-time clock (RTC)
provides a robust set of digital watch features, including current
time, stopwatch, and alarm. The RTC is clocked by a 32.768 kHz
crystal external to the ADSP-BF54x Blackfin processors. The
RTC peripheral has dedicated power supply pins so that it can
remain powered up and clocked even when the rest of the pro-
cessor is in a low-power state. The RTC provides several
programmable interrupt options, including interrupt per sec-
ond, minute, hour, or day clock ticks, interrupt on
programmable stopwatch countdown, or interrupt at a pro-
grammed alarm time.
The 32.768 kHz input clock frequency is divided down to a 1 Hz
signal by a prescaler. The counter function of the timer consists
of four counters: a 60-second counter, a 60-minute counter, a
24-hour counter, and a 32,768-day counter.
When enabled, the alarm function generates an interrupt when
the output of the timer matches the programmed value in the
alarm control register. There are two alarms. The first alarm is
for a time of day. The second alarm is for a day and time of
that day.
The stopwatch function counts down from a programmed value
with one-second resolution. When the stopwatch is enabled and
the counter underflows, an interrupt is generated.
Like the other peripherals, the RTC can wake up the
ADSP-BF54x processor from sleep mode upon generation of
any RTC wakeup event. Additionally, an RTC wakeup event can
wake up the ADSP-BF54x processors from deep sleep mode,
and it can wake up the on-chip internal voltage regulator from
the hibernate state.
