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 on­module 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.

AD14060/AD14060L

TIMING SPECIFICATIONS

This data sheet represents production-released specifications
for the AD14060 (5 V), and for the AD14060L (3.3 V). The
ADSP-21060 die components are 100% tested, and the
assembled AD14060/AD14060L units are again extensively
tested at speed and across temperature. Parametric limits were
established from the ADSP-21060 characterization followed by
further design and analysis of the AD14060/AD14060L package
characteristics.

The specifications are based on a CLKIN frequency of 40 MHz

= 25 ns). The DT derating allows specifications at other

(t

CK

CLKIN frequencies (within the minimum to maximum range
of the t

specification; see Table 3). DT is the difference

CK

between the actual CLKIN period and a CLKIN period of 25 ns:

DT = t

− 25 ns

CK

Use the exact timing information given. Do not attempt to
derive parameters from the addition or subtraction of others.

reflect statistical variations and worst cases. Consequently, one
cannot meaningfully add parameters to derive longer times.

Switching Characteristics specify how the processor changes its
signals. The user has no control over this timing—circuitry
external to the processor must be designed for compatibility
with these signal characteristics. Switching characteristics
specify what the processor does in a given circumstance. The
user can also use switching characteristics to ensure that any
timing requirement of a device connected to the processor
(such as memory) is satisfied.

Timing Requirement s apply to signals that are controlled by
circuitry external to the processor, such as the data input for a
read operation. Timing requirements guarantee that the
processor operates correctly with other devices.

These specifications apply when the AD14060/AD14060L is the bus master accessing external memory space.

These switching characteristics also apply for bus master synchronous read/write timing (see the Synchronous Read/Write—Bus Master

SYNCHRONOUS READ/WRITE—BUS MASTER

Use these specifications for interfacing to external memory systems that require CLKIN—relative timing or for accessing a slave
ADSP 2106x in multiprocessor memory space. These synchronous switching characteristics are also valid during asynchronous memory
reads and writes (see the Memory Read—Bus Master and Memory Write—Bus Master sections).

When accessing a slave ADSP-2106x, these switching characteristics must meet the slave’s timing requirements for synchronous
read/writes (see the Synchronous Read/Write—Bus Slave section). The slave ADSP-2106x must also meet these bus master timing
requirements for data and acknowledge setup and hold times.
