Abstract: Methods and apparatus for programmable logic devices including embedded processors having a dual-port SRAMs. A programmable logic integrated circuit includes a programmable logic portion having a plurality of logic elements, programmably configurable to implement user-defined combinatorial or registered logic functions, and an embedded processor portion coupled to the programmable logic portion. The embedded processor portion includes a processor, and a memory block coupled to the processor. The memory block includes a first plurality of memory cells for storing data, a second plurality of memory cells for storing data, a first port coupled to the first and second pluralities of memory cells, a second port coupled to the first and second pluralities of memory cells, and an arbiter coupled to the first port and the second port.

Abstract: A source synchronous external memory device returns data to a memory controller of an electronic device with its own clock signal, which allows the returned data to be captured with a high degree of accuracy. The captured data must then be resynchronized with the clock signal which controls the other components of the electronic device. This problem is particularly acute in the case of high speed memory devices, such as DDR (Double Data Rate) memory devices, and similar memory devices. Test data is written to the external memory device, and is then read back several times. Attempts are made to resynchronize the captured data with the system clock, with different relative variations in the phase of the captured data and the system clock, in order to select a value for the relative phase, which allows for optimum resynchronization.
