#77148 - RAM quantity & Interrupts Responding to: ???'s previous message |
Movies - not really, but Amiga .mod music - if we can only fit all the samples in RAM, playing them should be easy. Speaking of RAM, I think we should have more than 64k. Whether we try to provide programs with a way to bank code RAM to allow for programs larger than 64k is another question, but we should at least have more than 64k of space for pure data. Especially if we end up with DMA capability. We could poll one "activity bit" only. Then if set, just find the source. But true, interrupts and buffers are a prettier way to do it. Agreed on the activity bit and subsequently identifying the source. I'd like to have a maskable vblank interrupt. Allows for making smooth animation and a hundred of other valuable applications. vblank seemed to be the most used and abused interrupt both in Amiga and in Atari, and with 3 INT lines of the CPU we can afford it I think. Ahh, forgot all about the infamous Vertical Blank Interrupt. Oh, the memories of, as you said, abusing that poor little interrupt. Isn't that where I used to install my "real time clock" code that gave the Atari an hour/minute/second clock? :) Regards, Craig Steiner |
