TSPC603E
PowerPC 603e™ RISC MICROPROCESSOR Family
PID6-603e Specification
DESCRIPTION
The PID6-603e implementation of PC603e (after named 603e)
is a low-power implementation of reduced instruction set com-
puter (RISC) microprocessors PowerPC™ family. The 603e
implements 32-bit effective addresses, integer data types of 8,
16 and 32 bits, and floating-point data types of 32 and 64 bits.
The 603e is a low-power 3.3-volt design and provides four soft-
ware controllable power-saving modes.
The 603e is a superscalar processor capable of issuing and
retiring as many as three instructions per clock. Instructions
can execute out of order for increased performance ; however,
the 603e makes completion appear sequential. The 603e inte-
grates five execution units and is able to execute five instruc-
tions in parallel.
The 603e provides independent on-chip, 16-Kbyte, four-way
set-associative, physically addressed caches for instructions
and data and on-chip instruction and data memory manage-
ment units (MMUs). The MMUs contain 64-entry, two-way set-
associative, data and instruction translation lookaside buffers
that provide support for demand-paged virtual memory
address translation and variable-sized block translation.
The 603e has a selectable 32 or 64-bit data bus and a 32-bit
address bus. The 603e interface protocol allows multiple mas-
ters to complete for system resources through a central exter-
nal arbiter. The 603e supports single-beat and burst data
transfers for memory accesses, and supports memory-
mapped I/O.
The 603e uses an advanced, 3.3-V CMOS process technology
and maintains full interface compatibility with TTL devices.
The 603e integrates in system testability and debugging fea-
tures through JTAG boundary-scan capability.

1. INTRODUCTION
The 603e is a low-power implementation of the PowerPC microprocessor family of reduced instruction set commuter (RISC) micro-
processors. The 603e implements the 32-bit portion of the PowerPC architecture, which provides 32-bit effective addresses, integer
data types of 8, 16 and 32 bits, and floating-point data types of 32 and 64 bits. For 64-bit PowerPC microprocessors, the PowerPC
architecture provides 64-bit integer data types, 64-bit addressing, and other features required to complete the 64-bit architecture.
The 603e provides four software controllable power-saving modes. Three of the modes (the nap, doze, and sleep modes) are static in
nature, and progressively reduce the amount of power dissipated by the processor. The fourth is a dynamic power management
mode that causes the functional units in the 603e to automatically enter a low-power mode when the functional units are idle without
affecting operational performance, software execution, or any external hardware.
The 603e is a superscalar processor capable of issuing and retiring as many as three instructions per clock. Instructions can execute
out of order for increased performance ; however, the 603e makes completion appear sequential.
The 603 e integrates five execution units - an integer unit (IU), a floating-point unit (FPU), a branch processing unit (BPU), a load/store
unit (LSU) and a system register unit (SRU). The ability to execute five instructions in parallel and the use of simple instructions with
rapid execution times yield high efficiency and throughput for 603e-based systems. Most integer instructions execute in one clock
cycle. The FPU is pipelined so a single-precision multiply-add instruction can be issued every clock cycle.
The 603e provides independent on-chip, 16 Kbyte, four-way set-associative, physically addressed caches for instructions and data
and on-chip instruction and data memory management units (MMUs). The MMUs contain 64-entry, two-way set-associative, data
and instruction translation lookaside buffers (DTLB and ITLB) that provide support for demand-paged virtual memory address
translation and variable-sized block translation. The TLBs and caches use a least recently used (LRU) replacement algorithm. The
603e also supports block address translation through the use of two independent instruction and data block address translation (IBAT
and DBAT) arrays of four entries each. Effective addresses are compared simultaneously with all four entries in the BAT array during
block translation. In accordance with the PowerPC architecture, if an effective address hits in both the TLB and BAT array, the BAT
translation takes priority.
The 603e has a selectable 32 - or 64-bit - data bus and a 32-bit address bus. The 603e interface protocol allows multiple masters to
compete for system resources through a central external arbiter. The 603e provides a three-state coherency protocol that supports
the exclusive, modified, and invalid cache states. This protocol as a compatible subset of the MESI (modified/exclusive/shared/in-
valid) four-state protocol and operates coherently in systems that contain four-state caches. The 603e supports single-beat and burst
data transfers for memory accesses, and supports memory-mapped I/O.
The 603e uses an advanced, 3.3 V CMOS process technology and maintains full interface compatibility with TTL devices.
