43、 module. The board requires 1 amp. The power is supplied via 2 millimeter jack J1. If expansion boards are connected to the module a higher amperage power supply may be necessary. The board also has a 3.3 and 2.5 volt regulator to provide power to the lower voltage components.2.2 TMS320C54XX Memory

44、InterfaceThe EVM includes 192k Words of on board program ram memory and 64k words of on board data ram memory, providing a total of 256k words of off chip static ram. The board also features two 32k flash ROMs for boot loading.It is important to remember that internal memory has a higher precedence

45、than the external memory. For more information on the memory in the device populated in your EVM card please refer to Texas truments TMS320C54XX Users Guide. Futhermore, it is important to take into account that external memory is affected by wait-states. Wait state generation for off-chip memory sp

46、ace (data, program, or I/O) is done with the Software Wait State Generation Register(SWWSR). To obtain one waitstate off-chip memory bits in the SWWSR must be appropriately programmed. The board powers up with 7 wait-states. The EVM board does not generate wait states via the ready signal for extern

47、al program and data memory accesses, only I/O accesses use the ready signal.External memory decode is done via U14 a GAL20V8. The generic array device selects the RAM, FLASH ROM, or on board peripherals. The equations for the GAL are included in Appendix A. The figure below shows a one wait state pr

48、ogram space memory read followed by a data space memory write.The external Flash ROM is mapped into the upper 32K words of data and I/O space for boot loading. Note that this memory requires multiple wait states. The main purpose of this memory is to allow for the boot loading of programs via the C5
