Any Processor Code Compatibile with C31 ? - piyush kaul - Jul 11 5:25:00 2001

Hi, I want to upgrade my C31 chip to a higher memory chip, which is code compatible with C31. We have to add some new code but the current memory of C31 is proving to be insufficient. There is already a lot of code(in assembly) written for the C31 chip. Is there a way of changing the chip without having to rewrite the code. Regards Piyush __________________________________________________ |

Hello Piyush You may want to take a look at the TMS320VC33. This is essentialy a C31 built with the same process technology as the C5xxx and C6xxx families, so its like being on steroids! In your particular case you will find in addition to the original 2x1K blocks two more blocks of 16K words starting at 0x800000. All 34K words are dual access SRAM, so performance on a cycle by cycle basis is far better than external SRAM on a C31. Other benefits include Much lower power (3.3v IO and 1.8V core voltages) ~1mw/mhz using the C54x method of power measurement This is only 2x that of the C54x and its 32 bit float! Higher speed: -120 and -150 equivelent speeds to the C31 On chip x5 PLL for simpler clocking Internaly decoded strobes to simplify high speed external interfaces Selectable Edge triggerred interrupts (easier interrupt logic) JTAG debug (MPSD was getting pretty old) 144 TQFP package Volume pricing of $5 (-120 version in 100K volume) Hope this helps, Keith Larson Texas Instruments -------------------------------------------- At 10:25 PM 7/10/01 -0700, you wrote: >Hi, > >I want to upgrade my C31 chip to a higher memory chip, >which is code compatible with C31. >We have to add some new code but the current memory of >C31 is proving to be insufficient. >There is already a lot of code(in assembly) written >for the C31 chip.
