DSP16411 Digital Signal Processor
1 Features
! Twin DSP16000 dual-MAC cores perform up to
1140 million MACs per second at 285 MHz
! Low power:
— 1.2 V internal supply for power efficiency
— 3.3 V I/O pin supply for compatibility
! 322K x 16 on-chip RAM
! Centralized direct memory access unit (DMAU):
— Transparent peripheral-to-memory and mem-
ory-to-memory transfers
— Better utilization of DSP MIPS
— Simplifies management of system data flow
! 16-bit parallel interface unit (PIU) with direct mem-
ory access (DMA) provides host access to all DSP
memory
! Two enhanced serial I/O units (SIU0 and SIU1)
with DMA:
— Compatible with TDM highways such as T1/E1
and ST-bus
— Hardware support for µ-law and A-law com-
panding
! Core messaging units (MGU0 and MGU1) for inter-
processor communication
! On-chip, programmable, PLL clock synthesizer
eliminates need for high-speed clock input
! Two 7-bit control I/O interfaces (BIOs) for
increased flexibility and lower system costs
! 32-bit system and external memory interface
(SEMI) supports 16-bit or 32-bit synchronous or
asynchronous memories
! Two IEEE^® 1149.1 test ports (JTAG boundary
scan)
! Full-speed, in-circuit emulation hardware for each
core with eight address and two data watchpoint
units for efficient application development
! Supported by DSP16411 software and hardware
development tools
! 208-ball PBGA package (17 mm x 17 mm; 1.0 mm
ball pitch) for small footprint
2 Description
The DSP16411 is a digital signal processor (DSP)
optimized for communications infrastructure applica-
tions. Large, on-chip memory enables it to be pro-
grammed to perform numerous fixed-point signal
processing functions, including equalization, chan-
nel coding, or speech coding. The DSP16411 fea-
tures twin DSP16000 dual-MAC DSP cores and
enhanced DMA capabilities. Together, these features
deliver the performance required for second- and
third-generation infrastructure equipment.
The DSP16411 extends the performance of the
DSP16410CG with a higher maximum clock rate and
additional on-chip RAM, while maintaining low power
consumption, efficient software code density, and
small physical size. The DSP16411 is pinout and
code compatible with the DSP16410CG to protect
investments in hardware and software development.
