Abstract
A data processor in which a read operation, including misaligned data as operand data, can be performed in a single cycle. An alignment buffer having a register to hold data stored at one address in data memory is provided between the data memory and a data path unit. The alignment buffer outputs misaligned data by selecting misaligned data from data held in the register and data read from the data memory. The data held in the register is updated as word-aligned data is read out.
