NOTES: [1] Instruction clock speed for fastest member of family. Most processors issue one instruction per clock cycle; VLIW and superscalar processors may issue multiple instructions. [2] The BDTImark is a summary measure of DSP speed; higher is faster. See www.bdti.com for additional BDTImark scores. [3] In native words. Some processors share address space between program and data memories. [4] Unit prices quoted by manufacturers as of October, 1998. [5] CV = Contact vendor; n/a = information not available [6] Data is projected; processor has not yet been fabricated or is not yet available at speed shown.
