Data Movement
The DMA controllers support the following data movement scenarios:
•
•
•
•

Interrupter and Interrupt Handler
Tsi148 can be programmed to act as interrupter and an interrupt handler in a VME system. As
an interrupter, Tsi148 is capable of asserting interrupts on IRQ[7:1]O.
As an interrupt handler, Tsi148 has several VMEbus Interrupt Acknowledge registers which,
when read, generate an IACK cycle on the VMEbus (see
PCI/X-to-VME: Data is read from PCI/X and written to VME. The DMA buffer is
emptied while being filled.
VME-to-PCI/X: Data is read from VME and written to PCI/X. The DMA buffer is
emptied while being filled.
PCI/X-to-PCI/X: Data is read from PCI and written back later.
VME-to-VME: Data is read from VME and written back later
Data Pattern-to-VME: Data pattern written into DMA buffer, then written to VMEbus.
The DMA buffer is emptied while being filled.
Data Pattern-to-PCI/X: Data pattern written into DMA buffer, then written to PCI/X bus.
The DMA buffer is emptied while being filled.
Data patterns can be used for system debugging or clearing registers.
