The ADSP-TS201S processor provides programmable memory,
pipeline depth, and idle cycle for synchronous accesses; and
external acknowledge controls to support interfacing to pipe-
lined or slow devices, host processors, and other memory-
mapped peripherals with variable access, hold, and disable time
requirements.
Host Interface
The ADSP-TS201S processor provides an easy and configurable
interface between its external bus and host processors through
the external port (see Figure 4). To accommodate a variety of
host processors, the host interface supports pipelined or slow
protocols for ADSP-TS201S processor access of the host as slave
or pipelined for host access of the ADSP-TS201S processor as
slave. Each protocol has programmable transmission parame-
ters, such as idle cycles, pipe depth, and internal wait cycles.
The host interface supports burst transactions initiated by a host
processor. After the host issues the starting address of the burst
and asserts the BRST signal, the DSP increments the address
internally while the host continues to assert BRST.
The host interface provides a deadlock recovery mechanism that
enables a host to recover from deadlock situations involving the
DSP. The BOFF signal provides the deadlock recovery mecha-
nism. When the host asserts BOFF, the DSP backs off the
current transaction and asserts HBG and relinquishes the
external bus.
The host can directly read or write the internal memory of the
ADSP-TS201S processor, and it can access most of the DSP reg-
isters, including DMA control (TCB) registers. Vector
interrupts support efficient execution of host commands.
Multiprocessor Interface
The ADSP-TS201S processor offers powerful features tailored
to multiprocessing DSP systems through the external port and
link ports (see Figure 4). This multiprocessing capability pro-
vides the highest bandwidth for interprocessor communication,
including:
Up to eight DSPs on a common bus
On-chip arbitration for glueless multiprocessing
Link ports for point-to-point communication
The external port and link ports provide integrated, glueless
multiprocessing support.
The external port supports a unified address space (see Figure 3)
that enables direct interprocessor accesses of each
ADSP-TS201S processor’s internal memory and registers. The
DSP’s on-chip distributed bus arbitration logic provides simple,
glueless connection for systems containing up to eight
ADSP-TS201S processors and a host processor. Bus arbitration
has a rotating priority. Bus lock supports indivisible read-
modify-write sequences for semaphores. A bus fairness feature
prevents one DSP from holding the external bus too long.
The DSP’s four link ports provide a second path for interproces-
sor communications with throughput of 4G bytes per second.
The cluster bus provides 1G byte per second throughput—with
a total of 4.8G bytes per second interprocessor bandwidth (lim-
ited by SOC bandwidth).
SDRAM Controller
The SDRAM controller controls the ADSP-TS201S processor’s
transfers of data to and from external synchronous DRAM
(SDRAM) at a throughput of 32 bits or 64 bits per SCLK cycle
using the external port and SDRAM control pins.
The SDRAM interface provides a glueless interface with stan-
dard SDRAMs—16M bit, 64M bit, 128M bit, 256M bit, and
512M bit. The DSP supports directly a maximum of four banks
of 64M words × 32 bits of SDRAM. The SDRAM interface is
mapped in external memory in each DSP’s unified
memory map.
EPROM Interface
The ADSP-TS201S processor can be configured to boot from an
external 8-bit EPROM at reset through the external port. An
automatic process (which follows reset) loads a program from
the EPROM into internal memory. This process uses 16 wait
cycles for each read access. During booting, the BMS pin func-
tions as the EPROM chip select signal. The EPROM boot
procedure uses DMA Channel 0, which packs the bytes into
32-bit instructions. Applications can also access the EPROM
(write flash memories) during normal operation through DMA.
The EPROM or flash memory interface is not mapped in the
DSP’s unified memory map. It is a byte address space limited to
a maximum of 16M bytes (24 address bits). The EPROM or
flash memory interface can be used after boot via a DMA.
DMA CONTROLLER
The ADSP-TS201S processor’s on-chip DMA controller, with
14 DMA channels, provides zero-overhead data transfers with-
out processor intervention. The DMA controller operates
independently and invisibly to the DSP’s core, enabling DMA
operations to occur while the DSP’s core continues to execute
program instructions.
The DMA controller performs DMA transfers between internal
memory, external memory, and memory-mapped peripherals;
the internal memory of other DSPs on a common bus, a host
processor, or link port I/O; between external memory and exter-
nal peripherals or link port I/O; and between an external bus
master and internal memory or link port I/O. The DMA con-
troller performs the following DMA operations:
External port block transfers. Four dedicated bidirectional
DMA channels transfer blocks of data between the DSP’s
internal memory and any external memory or memory-
mapped peripheral on the external bus. These transfers
support master mode and handshake mode protocols.
Link port transfers. Eight dedicated DMA channels (four
transmit and four receive) transfer quad-word data only
between link ports and between a link port and internal or
