what architectural features in DSP prevent DSP from executingcontrol code efficiently?
Andrew Reilly wrote: [2] I've used simple post-increment addressing modes for the two loads, here, but most DSPs can do post decrement, non-unit stride, circular constraint and bit-reverse update modes as well. Describing bit-reverse addressing in C is a something involving a loop all on its own. The on... 5 Feb 2007 14:31

Designing a stack-machine CPU
Hi all, I am about to design a CPU, specialized for execution of compiled Lisp code. The basic design that proved useful in writing the compiler was that of a machine with two stacks: data stack and code stack indexed by two stack pointers *dsp* and *csp* respectively. These point into memory. Additionally... 12 Feb 2007 15:47
