描述 Description

The AD14160/AD14160L Quad-SHARC Ceramic Ball GridArray (CBGA) puts the power of the first generation AD14060(CQFP) DSP multiprocessor into a very high density ball gridarray package; now with additional link and serial I/O pinnedout, beyond that from the CQFP package. The core of the multiprocessoris the ADSP-21060 DSP microcomputer. The AD14x60modules have the highest performance—density and lowestcost— performance ratios of any in their class. They are idealfor applications requiring higher levels of performance and/orfunctionality per unit area.

The AD14160/AD14160L takes advantage of the built-inmultiprocessing features of the ADSP-21060 to achieve 480 peakMFLOPS with a single chip type, in a single package. The onchipSRAM of the DSPs provides 16 Mbits of on-moduleshared SRAM. The complete shared bus (48 data, 32 address)is also brought off-module for interfacing with expansionmemory or other peripherals.

The ADSP-21060 link ports are interconnected to providedirect communication among the four SHARCs as well as highspeed off-module access. Internally, links connect the SHARCin a ring. Externally, each SHARC has a total of 160 Mbytes/slink port bandwidth.

Multiprocessor performance is enhanced with embedded powerand ground planes, matched impedance interconnect, and optimizedsignal routing lengths and separation. The fully testedand ready-to-insert multiprocessor also significantly reducesboard space.
