480-MFLOP, Quad DSP, 3.3v, CQFP Package

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, 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, 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.
