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 multiprocessor
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 onchip 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.
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 optimized signal routing lengths and separation. The fully tested and ready-to-insert multiprocessor also significantly reduces board space.
