  2. Introduction • PowerPC is a RISC architecture based on IBM's POWER (Performance Optimization With Enhanced RISC). • It was jointly designed by Apple, IBM, and Motorola by early 1990s. • Aim was to form the basis of a new generation of high-performance low-cost products ranging from embedded controllers to massively parallel supercomputers. • PowerPC 600 family, PowerPC 700 family, PowerPC 900 family, PowerPC 400. ELEC6200-001: Han: PowerPC

  3. PowerPC 601 Architecture ELEC6200-001: Han: PowerPC

  4. Pipeline Structure ELEC6200-001: Han: PowerPC

  5. Instruction Queue and Dispatch Logic • It is Fed by eight-word bus from the cache. • During each cycle, the dispatch logic considers the bottom four entries of the instruction queue and dispatches up to three instructions. ELEC6200-001: Han: PowerPC

  6. Branch Processing Unit ELEC6200-001: Han: PowerPC

  7. Fixed-point execution unit ELEC6200-001: Han: PowerPC

  8. Floating-point Execution Unit • Supports IEEE-754 FP data types For both single and double-precision floating-point arithmetic operations. ELEC6200-001: Han: PowerPC

  9. Cache Unit & Memory Management Unit • 32 Kbytes • 8-way associative • Unified (instruction and data) • Capable of performing a complete read-modify- write every cycle • Performs the virtual to real address translation for load and store instructions • Acts as a backup for instruction fetch address translations • Provides support for segment oriented, page oriented and block oriented translations. ELEC6200-001: Han: PowerPC

  10. Sequencer Unit • It is an embedded support processor that assists the core CPU in handling many of the algorithmic functions of the PowerPC architecture. • It contains 1) 1K entry microcode ROS (Read-Only-Storage) 2) 8 single word general purpose registers 3) 32 word Private RAM 4) control logic required to execute the robust 18 bit instruction set ELEC6200-001: Han: PowerPC

  11. COP Unit • The Common On-chip Processor is the master control logic for the build-in self-test, debug and test features of the 601 chip. • It contains a linear feedback shift register (LFSR), a multiple input signature register (MISR) and the control logic required to sequence BIST operations. • It provides the capability to stop and start the internal clocks and to dump the state of all registers, RAMs and register files on the chip.
