类型：Soft IP
简短描述：Programmable DMA Controller Core
详细描述：
The C8237 Programmable DMA Controller core (C8237 core) is a peripheral interface circuit for microprocessor systems. The core is designed for use with an external, 8-bit address latch. It contains four independent channels and may be expanded to any number or channels by cascading additional controller chips. Each channel has a full 64K address and word count capability.
工艺：0.18um
代工厂：UMC
应用：The C8237 core is designed to improve system performance by allowing external devices to directly transfer information from the system memory.
特色：
Enable/Disable control of individual DMA requests
Four, independent DMA channels
Independent auto-initialization of all channels
Memory-to-Memory transfers
Memory block initialization
Address increment of decrement
Directly expandable to any number of channels
End of process input for terminating transfers
Software DMA requests
Independent polarity control for DREQ and DACK signals
The C8237 was developed in HDL and synthesizes to approximately 5,500 gates depending on the technology used
Functionality based on the Intel 8237
