The PDSP16488A is a fully integrated, application spe-
cific, image processing device. It performs a two dimensional
convolution between the pixels within a video window and a
set of stored coefficients. An internal multiplier accumulator
array can be multi-cycled at double or quadruple the pixel
clock rate. This then gives the window size options listed in
Table 1.
An internal 32k bit RAM can be configured to provide
either four or eight line delays. The length of each delay can
be programmed to the users requirement, up to a maximum of
1024 pixels per line. The line delays are arranged in two
groups,which may be internally connected in series or may be
configured to accept separate pixel inputs. This allows inter-
laced video or frame to frame operations to be supported.
The 8 bit coefficients are also stored internally and can
be downloaded from a host computer or from an EPROM. No
additional logic is required to support the EPROM and a single
device can support up to 16 convolvers.
The PDSP16488A contains an expansion adder and
delay network which allows several devices to be cascaded.
Convolvers with larger windows can then be fabricated as
shown in Table 2.
Intermediate 32 bit precision is provided to avoid any
danger of overflow, but the final result will not normally occupy
all bits. The PDSP16488A thus provides a multiplier in the
output path, which allows the user to align the result to the
most significant end of the 32 bit word.

NOTE
Polyimide is used as an inter-layer dielectric and as
glassivation.
Polymeric material is also used for die attach which according
to the requirement in paragraph 1.2.1.b. (2) precludes
catagorising this device as fully compliant. In every other
respect this device has been manufactured and screened in full
accordance with the requirements of Mil-Std 883 (latest revi-
sion).
CHANGE NOTIFICATION
The change notification requirements of MIL-PRF-38535 will
be implemented on this device type. Known customers will be
notified of any changes since the last buy when ordering further
parts if significant changes have been made.
