“BC_Expander” where scaling up/down is performed using the Bi-Cubic method
“Blender” where Blend processing is performed
“Read FIFO buffer” where source data is accumulated
“Write FIFO buffer” where destination data is accumulated
“Transfer address control circuit” where rotation / simple scaling down processing is
performed
“AHB slave block” where the access from the AHB bus to control registers is controlled
“AHB master block” where the data access to the AHB bus is controlled
“Interrupt control block” where interrupts are generated by monitoring processing
completion and error occurrence
Block Diagrams
