DSP16410CG Digital Signal Processor
1 Features
! Twin DSP16000 dual-MAC cores perform up to
780 million MACs per second at 195 MHz
! Low power:
— 1.575 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 DSP16410CG software and hard-
ware development tools
! 208-ball PBGA package for small footprint
(17 mm x 17 mm; 1.0 mm ball pitch)
2 Description
The DSP16410CG, also known as the DSP16410C,
is a digital signal processor (DSP) optimized for com-
munications infrastructure applications. Large, on-
chip memory enables it to be programmed to perform
numerous fixed-point signal processing functions,
including equalization, channel coding, or speech
coding. This is the first Agere wireless product to fea-
ture 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 DSP16410CG achieves best-in-class signal pro-
cessing performance while maintaining efficient soft-
ware code density, low power consumption, and small
physical size.
