30 / 94 page 30 Altera Corporation Cyclone FPGA Family Data Sheet Preliminary Information Independent Clock Mode The M4K memory blocks implement independent clock mode for true dual-port memory. In this mode, a separate clock is available for each port (ports A and B). Clock A controls all registers on the port A side, while clock B controls all registers on the port B side. Each port, A and B, also supports independent clock enables and asynchronous clear signals for port A and B registers. Figure 17 shows an M4K memory block in independent clock mode. Figure 17. Independent Clock Mode Note (1) Note to Figure 17: (1) All registers shown have asynchronous clear ports. Input/Output Clock Mode Input/output clock mode can be implemented for both the true and simple dual-port memory modes. On each of the two ports, A or B, one clock controls all registers for inputs into the memory block: data input, wren , and address. The other clock controls the block’s data output registers. Each memory block port, A or B, also supports independent clock enables and asynchronous clear signals for input and output registers. Figures 18 and 19 show the memory block in input/output clock mode. 6 D ENA Q D ENA Q D ENA Q data A[ ] address A[ ] Memory Block 256 ´ 16 (2) 512 ´ 8 1,024 ´ 4 2,048 ´ 2 4,096 ´ 1 Data In Address A Write/Read Enable Data Out Data In Address B Write/Read Enable Data Out clken A clock A D ENA Q wren A 6 LAB Row Clocks q A[ ] 6 data B[ ] address B[ ] clken B clock B wren B q B[ ] ENA AB ENA D Q D ENA Q byteena A[ ] Byte Enable A Byte Enable B byteena B[ ] ENA D Q ENA D Q ENA D Q D Q Write Pulse Generator Write Pulse Generator |
