  • Sharing bandwidth of a single port SRAM between at least one DMA peripheral and a CPU operating with a quadrature clock
    Patent number: 7739433
    Abstract: A dual or triple access interface (e.g., hardware and software implementation) allows a CPU and at least one DMA peripheral, e.g., Universal Serial Bus (USB) DMA engine, to transfer data in and/or out of a common single port SRAM by negotiating access requests between the CPU and the DMA peripheral, and then subsequently forms memory cycles to the single port SRAM to satisfy both the CPU's and DMA peripheral's memory access throughput requirements. This allows the CPU and the at least one DMA peripheral to access a shared single port SRAM by time multiplexing granted accesses between, for example, two or three simultaneous memory access requests, thus eliminating the need for a dual port memory.

  • Display device using demultiplexer
    Patent number: 7738512
    Abstract: Disclosed is a display device using a demultiplexer. The demultiplexer sequentially samples the data current that is time-divided and applied by a data driver, and holds it to the data lines. Since the demultiplexer is to sample the data currents corresponding to N data lines during one horizontal period when performing 1:N demultiplexing, the data current corresponding to one data line is sampled during the 1/N horizontal period. In the present invention, a signal line coupled between the demultiplexer and the data driver is precharged with the current before coupling a precharge circuit to a sample/hold circuit and sampling the data current. The precharge current is M times the data current where M is a real number greater than 1.
