Description
The PID7t-603e implementation of PowerPC 603e (after named 603r) is a low-power
implementation of reduced instruction set computer (RISC) microprocessors Pow-
erPC family. 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 2.5/3.3-volt design and provides four software controllable
power-saving modes.
The 603r is a superscalar processor capable of issuing and retiring as many as three
instructions per clock. Instructions can execute out of order for increased perfor-
mance; however, the 603r makes completion appear sequential. The 603r 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 and on-chip instruction and data Memory
Management Units (MMUs). The MMUs contain 64-entry, two-way set-associative,
data and instruction translation look aside bu ffers that provide suppor t for
demand-paged vir tual memor y address translation and variable-sized block
translation.
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 complete for system resources through a
central external arbiter. The 603r supports single-beat and burst data transfers for
memory accesses, and supports memory-mapped I/O.
