DSP16410B Digital Signal Processor
1 Features
Twin DSP16000 dual-MAC cores for high through-
put:
—Up to 740 million MACs per second at 185 MHz
—Supports 16+ channels of speech coding or
modem processing
Low power:
—1.8 V internal supply for power efficiency
—3.3 V I/O pin supply for compatibility
194K x 16 on-chip RAM
Centralized direct memory access unit (DMAU):
—Transparent peripheral-to-memory and memory-
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 compand-
ing
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 DSP16410B software and hardware
development tools
Two ball grid array package options for small foot-
print:
— 208-ball PBGA (17 mm x 17 mm; 1.0 mm ball
pitch)
— 256-ball EBGA (27 mm x 27 mm; 1.27 mm ball
pitch)
2 Description
The DSP16410B 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, channel
coding, compression, and speech coding. This is the
first Agere wireless product to feature twin DSP16000
dual-MAC DSP cores and enhanced DMA capabili-
ties. Together, these features deliver the performance
required for second- and third-generation infrastruc-
ture equipment.
The DSP16410B achieves best-in-class signal pro-
cessing performance while maintaining efficient soft-
ware code density, low power consumption, and small
physical size.
