Two Dimensional Convolver
The Intersil HSP48908/883 is a high speed Two Dimensional
Convolver which provides a single chip implementation of a
video data rate 3 x 3 kernel convolution on two dimensional
data. It eliminates the need for external data storage through
the use of the on-chip row buffers which are programmable
for row lengths up to 1024 pixels.
There are internal register banks for storing two independent
3 x 3 filter kernels, thus, facilitating the implementation of
adaptive filters and multiple filter operations on the same
data. The pixel data path also includes an on-chip ALU for
performing real-time arithmetic and logical pixel point
operations.
Data is provided to the HSP48908/883 in a raster scan
noninterlaced fashion, and is internally buffered on images
up to 1024 pixels wide for the 3 x 3 convolution operation.
Images with larger rows and convolution with larger kernel
sizes can be accommodated by using external row buffers
and/or multiple HSP48908/883s. Coefficient and pixel input
data are 8-bit signed or unsigned integers, and the 20-bit
convolver output guarantees no overflow for kernel sizes up
to 4 x 4. Larger kernel sizes can be implemented however,
since the filter coefficients will normally be less than their
maximum 8-bit values.
The HSP48908/883 is manufactured using an advanced
CMOS process, and is a low power fully static design. The
configuration of the device is controlled through a standard
microprocessor interface and all inputs/outputs are TTL
compatible.

NOTES:
6. This specification applies only to the case where the HSP48908/883 is being written to during an active convolution cycle. It must be met in order
to achieve predictable results at the next rising clock edge. In most applications, the configuration data and coefficients are loaded
asynchronously and the t
LCS
Specification may be disregarded.
7. While FRAME is an asynchronous signal, it must be deasserted a minimum of t
FS
ns prior to the rising clock edge which is to begin loading pixel
data for a new frame.
8. Transition is measured at
±200mV
from steady state voltage with loading as specified in test load circuit with C
L
= 40pF.
9. AC Testing is performed as follows: Input levels (CLK input) 4.0V and 0V, input levels (all other inputs) 0V and 3.0V, timing reference levels
(CLK) = 2.0V, (others) = 1.5V. Output load per test load circuit with C
L
= 40pF. Output transition is measured at V
OH
1.5V and V
OL
1.5V.
