ABSTRACT:
According to one embodiment of the invention, a method of accessing instruction data from a memory comprises steps of specifying a predetermined address of a memory for storing instruction data; writing instruction data to the predetermined address in the memory; reading the instruction data from the predetermined address after the step of writing instruction data; and determining whether the instruction data is valid. According to another embodiment of the invention, a method describes a method of accessing instruction data from a memory by way of first and second data buses. According to a further embodiment, instruction data read back from the memory is multiplexed to a memory controller. A circuit for accessing instruction data written to a memory is also described.
