Zoran Corporation 

SIGNAL DESCRIPTIONS

Integrated Color Space / Raster-To-Block Converter

Table 1: PIXEL Input/Output

Signal

PXIN[23:0]

PXOUT[23:0]

PXOE

HIN

VIN

HOUT

VOUT

PXEN

I/O

Description

I

Pixel data input bus.

O Pixel data output bus.

I

PXOUT bus output enable.

I

Horizontal input data enable. Rising edge indicates beginning of scan line and start of NAX and PAX counts. For

synchronization of PXIN.

I

Vertical input data enable. Rising edge indicates beginning of picture and start of NAY and PAY counts. For synchro-

nization of PXIN.

O Horizontal output data enable. Follows HIN by internal processing delay. For synchronization of PXOUT.

O Vertical output data enable. Follows VIN by internal processing delay. For synchronization of PXOUT.

I

Pixel enable for PXIN and PXOUT. For discontinuous transfers.

Table 2: Host Interface

Signal

ADD[1:0]

DATA[7:0]

WR

RD

CS

CBSY

I/O

Description

I

Internal registers address input.

I/O Internal registers data bus.

I

Write enable to internal registers. Written to on rising edge.

I

Read enable for internal registers.

I

Chip select for host interface.

I

CODEC busy. Indicates that the pixel side is ready to exchange strip buffers, but the ZR36050 side is not ready yet.

Table 3: Strip Buffer Memory Interface

Signal

MDATA[15:0]

MADD[15:0]

MWE

MOE

I/O

I/O Memory data bus for strip buffer.

O Memory address for strip buffer.

O Memory write enable for strip buffer.

O Memory output enable for reading strip buffer.

Description

Table 4: ZR36050 Interface

Signal

I/O

Description

BDATA[7:0]

I/O Block data bus, connected to ZR36050 PIXEL bus.

DSYNC

I/O Block data synchronization with ZR36050.

STOP

I/O Data flow control with ZR36050.

EOS

COMP [1]

I/O End of scan control with ZR36050.

I

Compression/expansion mode indicator from ZR36050.

1. The state of the COMP pin determines the direction of the bidirectional pins BDATA, DSYNC, STOP, and EOS. When COMP is high (the ZR36050 is in compression

mode), BDATA, DSYNC and EOS are outputs and STOP is an input. When COMP is low (the ZR36050 is in expansion mode), BDATA, DSYNC and EOS are inputs

and STOP is an output.
