Programmable integrated circuits with specialized processing blocks such as digital signal processing (DSP) blocks are provided. Each DSP block may include embedded built-in self-test circuitry implemented using existing input registers and output registers in the DSP blocks. The input registers may be selectively coupled in a loop to serve as a linear feedback shift register (LFSR). The output registers may be selectively coupled in a chain to serve as a multiple input signature register (MISR).

Configured in this way, the LIFR and the MISR circuits of the DSP blocks are not implemented using soft logic and can therefore easily meet performance criteria.

A system for mapping control and user data includes a direction scanner, an address calculator, a collision detector, a buffer, and a mapper for mapping control and user data from a first memory to a second memory. The direction scanner determines the highest priority value of to a code word index. The address calculator calculates start and end addresses of the highest priority value. When an address from an address range, defined by the start and end addresses, is already mapped to other control data, the collision detector detects a collision and generates feedback data. The address calculator outputs modified start and end addresses based on the feedback data. When no collision is detected, the address calculator outputs the modified start and end addresses to the buffer. The mapper then maps the control and user data to the modified start and end addresses in the second memory.

The present invention provides a monolithic gate driver that includes fewer elements than in conventional configurations. A plurality of stages included in a shift register are divided into a plurality of stage circuit groups, where each stage circuit group includes the stage circuits of P adjacent stages (two stages, for example). Each stage circuit group includes a stabilization node and a stabilization node controller that controls the voltage of the stabilization node. The stabilization node controller includes: thin-film transistors in which the gate terminals thereof are connected to output control nodes, the drain terminals thereof are connected to the stabilization node, and the source terminals thereof are connected to an input terminal for a DC supply voltage; and a thin-film transistor for changing the voltage of the stabilization node to a high level.

A shift register, a driving method, a gate driving circuit and a display device are disclosed. The input module controls the potential of the first node. The first reset module controls the potential of the first node. The second reset module controls the potential of the driving signal output terminal. The first output module controls the potential of the driving signal output terminal under the control of the first node. The second output module controls the potential of the driving signal output terminal under the control of the second node. The pull-down driving module controls the potentials of the first node and the second node. Since the node control signal at the node control signal terminal can eliminate the noise on the first node resulting from the change in the first clock signal, the output stability of the shift register can be improved.

A memory system and memory controller for interleaving volatile and non-volatile memory accesses are described. In the memory system, the memory controller is coupled to the volatile and non-volatile memories using a shared address bus. Activate latencies for the volatile and non-volatile memories are different, and registers are included on the memory controller for storing latency values. Additional registers on the memory controller store precharge latencies for the memories as well as page size for the non-volatile memory. A memory access sequencer on the memory controller asserts appropriate chip select signals to the memories to initiate operations therein.
