GENERAL DESCRIPTION
The AD14160/AD14160L Quad-SHARC Ceramic Ball Grid
Array (CBGA) puts the power of the first generation AD14060
(CQFP) DSP multiprocessor into a very high density ball grid
array package; now with additional link and serial I/O pinned
out, beyond that from the CQFP package. The core of the multi-
processor is the ADSP-21060 DSP microcomputer. The AD14x60
modules have the highest performance—density and lowest
cost— performance ratios of any in their class. They are ideal
for applications requiring higher levels of performance and/or
functionality per unit area.
The AD14160/AD14160L takes advantage of the built-in
multiprocessing features of the ADSP-21060 to achieve 480 peak
MFLOPS with a single chip type, in a single package. The on-
chip SRAM of the DSPs provides 16 Mbits of on-module
shared SRAM. The complete shared bus (48 data, 32 address)
is also brought off-module for interfacing with expansion
memory or other peripherals.
SHARC is a registered trademark of Analog Devices, Inc.
The ADSP-21060 link ports are interconnected to provide
direct communication among the four SHARCs as well as high
speed off-module access. Internally, links connect the SHARC
in a ring. Externally, each SHARC has a total of 160 Mbytes/s
link port bandwidth.
Multiprocessor performance is enhanced with embedded power
and ground planes, matched impedance interconnect, and opti-
mized signal routing lengths and separation. The fully tested
and ready-to-insert multiprocessor also significantly reduces
board space.
