Configuration input port
Indicates that the CS6100 is ready to accept configuration data
Configuration input strobe
Indicates that AutoMode
Causes the CS6100 to enter AutoEncode state
Indicates that the CS6100 is currently initializing its internal memories
Indicates number of tables defined. Bits[7:4] indicate Huffman Tables. Bits [3:0] indicate quantization
tables, 1 bit/table
Encoding parameter bus
Signal specifying parameters to be placed on port PValue
Indicates valid coding parameters
Indicates that a SOS segment has been input via CfgIn or has been read from the configuration memory
and the CS6100 is about to start encoding a scan
CS6100 internal status and error flag status register
JpgOut stream configuration port
JPEG output stream
Indicates that valid data is available on JpgOut
Informs core to place next 16-bit word of output data onto JpgOut. Data held if JpgNext not asserted
Indicates that the data on port JpgOut is the last one of an encoded JPEG data stream
Indicates that the last data of the encoded JPEG data stream has been output on port JpgOut
Sample data input port
Indicates the first pixel of an 8x8 block
Indicates that the CS6100 is ready to accept data
Indicates that the current MCU row is the last one of the scan
Test type selector
Marks the first value in the first 8x8-output block of test data
Marks the first value in each 8x8-output block of test data
11-bit output test data port – displays DCT coefficients or quantized coefficients
Indicates valid test data output
Causes memories to be bypassed for test purposes
