Digital control for embedded applications
Rachel Leach · 2002
With the reduction of the cost and increase in performance of digital microprocessors, many system designers are performing both system control and signal processing with the same microcontroller. The author presents the PowerPC Architecture/sup TM/ which has many implementations with different pipeline depths, number of execution units, instruction timings, and instruction issue rates and protocols. The Power Architecture has two instruction classes: a floating point multiply-add instruction and a load/store with update. Examples are given using the MPC505, MPC602, MPC603, MPC604, MPC821, and MPC860 microprocessors.
