Provided is a low power consumption processor. The processor includes: a plurality of blocks; a memory storing instructions that control each of the plurality of blocks; and a multi power controller generates a signal that activates at least one of the plurality of blocks according to an address storing the instruction, and provides a normal power voltage or a reduction power voltage in response to the activation signal.

Low power consumption processor

Provided is a direct memory access (DMA) controller. The DMA controller includes a plurality of channel groups and a channel group controller. Each of the channel groups has a plurality of DMA channels, and the channel group controller controls enablement of the DMA channels in units of channel groups. Herein, the channel group controller enables the DMA channels of at least one of the channel groups in data transmission.

Direct memory access controller and data transmitting method of direct memory access channel

Provided is a bit stream processor using a reduced table lookup. The bit stream processor includes a bit stream exclusive register in a general purpose register in order to process data of a variable length effectively. Additionally, the bit stream processor an instruction of a table lookup method to which a prefix method is applied and a bit stream exclusive instruction in order to reduce an entire memory size.

Method of driving bit stream processor

Provided is a data processing circuit. A control unit outputs an operation control signal and a memory control signal. A plurality of program memories each outputs a command in response to the memory control signal. A plurality of arithmetic sections each selectively performs any one of the commands from the plurality of program memories in response to the operation control signal. Operation modes of the data processing circuit can be flexibly changed according to operation environments.

Arithmetic units responsive to common control signal to generate signals to selectors for selecting instructions from among respective program memories for SIMD / MIMD processing control
