An image deblocking filter comprises an instruction memory. A decision unit executes instructions stored in the instruction memory to decide a first path or a second path of instruction fetching from the instruction memory to an execution unit. The execution unit is operable to execute a first instruction in the decided path the in one clock cycle. The first instruction represents a complex of three arithmetic operations and two bitwise operations for three variable operands and two constant operands. The first and second paths respectively realize deblocking formulae of a first and a second image compression standard.

A signal relay device for accessing an external memory is provided. The signal relay device includes a bus arbiter and a burst access engine. The bus arbiter performs bus arbitration among main masters on a bus. The burst access engine exchanges signals with the bus arbiter and an external memory controller. The signal relay device facilitates data transfer of large groups of read/write commands between the main masters and the external memory controller.
