The SETC CNF (configure B0 as data memory) and CLRC CNF (configure B0 as program memory) instructions allow dynamic configuration of the memory maps through software by Crack DSP Controller TMS320F28021 Memory. When using block 0 as program memory, instructions can be downloaded from external program memory into on-chip RAM and then executed. When using on-chip RAM, or high-speed external memory, the ’x240 runs at full speed with no wait states.
The ability of the DARAM to allow two accesses to be performed in one cycle coupled with the parallel nature of the ’x240 architecture enables the device to perform three concurrent memory accesses in any given machine cycle only after Crack DSP MCU TMS320F28035 Eeprom Memory. Externally, the READY line can be used to interface the ’x240 to slower, less expensive external memory. Downloading programs from slow off-chip memory to on-chip RAM can speed processing while cutting system costs.
The ’C240 device contains 16K words of mask-programmable ROM located in program memory space. Customers can arrange to have this ROM programmed with contents unique to any particular application from Crack DSP Controller TMS320F28021 Memory. The ROM is enabled or disabled by the state of the MP/MC control input upon resetting the device. The ROM occupies the lowest block of the program memory when enabled. When disabled, these addresses are located in the device’s external program memory space.
