PRELIMINARY
Strip Buffer Capacity
The address range for the strip buffer is 64K (limited by the
number of address bits for the strip buffer memory). Given that
the strip buffer is 16 bits wide, this gives a maximum memory
capacity of 128K bytes that can be accessed.
The raster to block process stores even blocks for each element
in the A strip buffer memory, and the odd blocks for each
element in the B strip bufer memory (see figure TBD). This
divides the storage capacity required for the total strip evenly
between the A and B sides of the memory.
The table below is used to calculate the required total strip buffer
memory capacity (evenly distributed between the A and B
memories) of the strip buffer.
Capacity = 2 x K x L x HWidth x D
Where...
I
“2” is required because the strip buffer is double buffered
I
K indicates the number of bytes of data required for each
pixel
I
L indicates the number of lines of data required to form a strip
I
D is equal to “1” for no decimation delected, and is equal to
“1/2” if decimation is selected.
The maximum number of pixels per line that can be entered for
each mode is given in the table below. This number for the
maximum number of pixels per line is determined by the
maximum addressable strip buffer capacity. When less strip
memory is used (i.e., less than 64K x 16-bits), then the numbers
in the table below must be scaled accordingly.
The limitations for the VHeight values are given in the table
below. These limitations are imposed so that the image size cor-
responds to a complete Minimum Configurable Unit (as defined
in the JPEG specification)

Coder Bus Interface
The ZR36015 Raster to Block Converter interfaces directely to
the ZR36050 JPEG Codec.
The Coder Bus Interface consists of the DSYNC, BDATA(7:0),
STOP, EOS, and COE signals (see figure 2).
The Direction of these interface for each mode of operation is
given in the table below.
Table 5: Coder Bus Interface
The data transfer rate on BDATA(7:0) is equal to the SYSCLK
rate for all formats.
The mode of operation is determined by the “EDC” bit in the
Mode Register when the GO bit is asserted.
Bidirectional signals are availiable as inputs immediately after a
hard reset, and as outputs after the GO bit in the Mode Register
has been set.
The COE signal enables the outputs of the bidirectional signals
of the Code Bus Interface. When COE is High, the outputs for
Compression Mode are enabled, when COE is Low, the output
for Expansion mode are enabled. When the ZR36015 is used
