Multi-channel DMA Controller Page 1 of 4 Home > Products > Intellectual Property > Lattice IP Cores > Multi-channel DMA Controller Multi-channel DMA Controller Overview The Multi-Channel Direct Memory Access (MCDMA) Controller is designed to improve microprocessor system performance by allowing external devices to directly transfer information from the system memory. Memory-tomemory transfer capability is also supported. The MCDMA Controller core supports two modes: 8237 and non-8237. When the 8237 mode is selected, it configures the core to be compatible with the Intel 8237A DMA Controller with a few variations. These variations are listed in the "Compatibility Differences with the 8237 Intel Device" section of the datasheet. The 8237 mode supports four independent channels while the non-8237 mode supports up to 16 independent channels. Features Selectable 8237 Mode Configurable up to 16 Independent DMA Channels for Non-8237 Mode Configurable Data Width of 8, 16, 32 or 64 Bits for Non-8237 Mode Configurable Address Width of 16, 24 or 32 Bits for Non-8237 Mode Configurable Word Count Register Width for Non-8237 Mode Independent Auto-initialization of All Channels Memory-to-Memory Transfers on Single, Block, and Demand Transfer Modes Memory Block Initialization Software DMA Requests Evaluation Configurations Evaluation Configurations Available for Series 4 ORCA FPGAs and 1 FPSCs Name of Parameter File dma_mc_o4_2_001.lpc dma_mc_o4_2_002.lpc http://www.latticesemi.com/products/intellectualproperty/ipcores/multichanneldmacontro... 10/11/2011 Multi-channel DMA Controller Page 2 of 4 Mode 8237 Non-8237 LUTs 1258 2661 200 499 Registers 524 1187 SysMem EBR N/A N/A External Pins 59 125 fMAX (MHz) 58 66 # of Channels 4 4 Data Bus Width 8 32 Address Bus Width 16 32 Word Count Width 16 16 ORCA4 PFUs 2 1 TM 2 PFU is a standard logic block of some Lattice devices.
