Quad-SHARCs AD14060/AD14160

480-MFLOP, Single Package Multiprocessor

http://www.analog.com/milsystems

The AD14060 Quad-SHARC is a first genera-

tion (CQFP) DSP multiprocessor. Using high-

density packaging techniques, the module fits

four SHARCs in approximately 30% of the

space required using discrete packages.

The AD14160 Quad-SHARC Ceramic Ball

Grid Array (CBGA) puts the power of the first

generation AD14060 (CQFP) DSP multiproces-

sor into a very high density ball grid array

package, the module fits four SHARCs in

approximately 30% of the space required using

discrete packages; now with additional link and

serial I/O pinned out, beyond that from the

CQFP package.

The core of the multiprocessors is the

ADSP-21060 DSP Microcomputer. The

AD14060/ AD14160 modules have the highest

performance-density and lowest cost-perfor-

mance ratios of any multiprocessors in

their class. They are ideal for applica-

tions requiring higher levels of perfor-

mance and/or functionality per unit

area.

The AD14060/AD14160 take advan-

tage of the built-in multiprocessing

features of the ADSP-21060, to

achieve 480 peak MFLOPS with a sin-

gle 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-bit data,

32-address) is also brought off-module

for interfacing with expansion memo-

ry and/or other peripherals.

Multi-SHARC designs with tight area/volume

constraints, such as large array and image

processors, smart missiles, avionics, and others

will benefit. The AD14060/AD14160 are

available as both industrial and MIL-SMD

grade parts in 5V (AD14060/AD14160) or

3.3V (AD14060L/AD14160L) versions.

With 480 MFLOPS of throughput, the

AD14060/AD14160 have no competition. TI's

Dual C40 MCM provides a similar function,

but delivers only 80 MFLOPS in a significantly

larger package, and roughly equivalent cost.

The Quad-SHARC AD14060/AD14160 is tar-

geted to be priced such that users can take

advantage of system cost advantages of using

MCMs.
