TSPC603R
1. Description
The PID7t-603e implementation of the PowerPC 603e (renamed after the 603R) is a low-power imple-
mentation of the Reduced Instruction Set Computer (RISC) microprocessor PowerPC family. The 603R
is pin-to-pin compatible with the PowerPC 603e and 603P in a Cerquad package. The 603R 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 603R is a low-power 2.5/3.3V design and provides four software controllable power-saving modes.
This device is a superscalar processor capable of issuing and retiring as many as three instructions per
clock. Instructions can be executed in any order for increased performance, but, the 603R makes com-
pletion appear sequential. It integrates five execution units and is able to execute five instructions in
parallel.
The 603R provides independent on-chip, 16-Kbyte, four-way set-associative, physically addressed
caches for instructions and data, as well as on-chip instructions, and data Memory Management Units
(MMUs). The MMUs contain 64-entry, two-way set-associative, data and instruction translation look
aside buffers that provide support for demand-paged virtual memory address translation and vari-
able-sized block translation. The 603R has a selectable 32- or 64-bit data bus and a 32-bit address bus.
The interface protocol allows multiple masters to compete for system resources through a central exter-
nal arbiter. The device supports single-beat and burst data transfers for memory accesses, and supports
memory-mapped I/Os.
The 603R uses an advanced, 2.5/3.3V CMOS process technology and maintains full interface compati-
bility with TTL devices. It also integrates in-system testability and debugging features through JTAG
boundary-scan capabilities.

4. Overview
The 603R is a low-power implementation of the PowerPC microprocessor family of Reduced Instruction
Set Computing (RISC) microprocessors. The 603R implements the 32-bit portion of the PowerPC archi-
tecture, 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 architec-
ture provides 64-bit integer data types, 64-bit addressing, and other features required to complete the
64-bit architecture.
The 603R provides four software controllable power-saving modes. Three of the modes (nap, doze, and
sleep) 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 603R to auto-
matically enter a low-power mode when the functional units are idle without affecting operational
performance, software execution, or any external hardware.
The 603R is a superscalar processor capable of issuing and retiring as many as three instructions per
clock. Instructions can be executed in any order for increased performance, but, the 603R makes com-
pletion appear sequential.
The 603e integrates five execution units:
• an Integer Unit (IU)
• a Floating-point Unit (FPU)

• a Branch Processing Unit (BPU)
• a Load/Store Unit (LSU)
• 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 603R-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 603R provides independent on-chip, 16 Kbyte, four-way set-associative, physically addressed
caches for instructions and data, as well as on-chip instruction and data Memory Management Units
(MMUs). The MMUs contain 64-entry, two-way set-associative, Data and Instruction Translation Looka-
side 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) replace-
ment algorithm. The 603R 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 has priority.
The 603R has a selectable 32- or 64-bit data bus and a 32-bit address bus. The 603R interface protocol
allows multiple masters to compete for system resources through a central external arbiter. The 603R
provides a three-state coherency protocol that supports the exclusive, modified, and invalid cache
states. This protocol is a compatible subset of the MESI (Modified/Exclusive/Shared/Invalid) four-state
protocol and operates coherently in systems that contain four-state caches. The 603R supports sin-
gle-beat and burst data transfers for memory accesses, and supports memory-mapped I/Os.
The 603R uses an advanced, 0.29 µm 5-metal-layer CMOS process technology and maintains full inter-
face compatibility with TTL devices.
5. Signal Description
Figure 5-1 on page 5, Table 10-5
and
Table 10-6 on page 20
describe the signals on the TSPC603R and
indicate signal functions. The test signals, TRST, TMS, TCK, TDI and TDO, comply with the subset
P-1149.1 of the IEEE testability bus standard.
The three signals LSSD_MODE, LI_TSTCLK and L2_TSTCLK are test signals for factory use only and
must be pulled up to V
DD
for normal machine operations.
