GENERAL DESCRIPTION
The AD14060/AD14060L Quad-SHARC is the first in a family
of high performance DSP multiprocessor modules. The core of
the multiprocessor is the ADSP-21060 DSP microcomputer. The
AD14060/AD14060L has the highest performance-to-density
and lowest cost-to-performance ratios of any in its class. It is
ideal for applications requiring higher levels of performance
and/or functionality per unit area.
The AD14060/AD14060L 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,

expansion memory or other peripherals.
The ADSP-21060 link ports are interconnected to provide direct
communication among the four SHARCs, as well as high speed
off-module access. Internally, each SHARC has a direct link port
connection. Externally, each SHARC has a total of 120 Mbytes/s
link port bandwidth.
Multiprocessor performance is enhanced with embedded power
and ground planes, matched impedance interconnect, and
optimized signal routing lengths and separation. The fully
tested and ready-to-insert multiprocessor also significantly
reduces board space.
