1.	What does MAC instruction of DSP56000 stand for?(a) multiply accumulator(b) multiple access(c) multiple accounting(d) multiply accumulator counterI have been asked this question in an interview.The query is from The Berkeley RISC Model and Digital Signal Processing in section Embedded Processors of Embedded Systems
Answer» The correct choice is (a) multiply accumulator The EXPLANATION is: When MAC instruction is EXECUTED, the two of the 24-bit ADDITIONAL REGISTERS are multiplied together and then added or subtracted from A and B. It takes place in a single machine cycle of 75ns at 27MHz.
