Page 25: Theory Of Operation
Theory of Operation Processor Board : F9601-11-16 MPC603e Processor This processor board is based on the Power MPC603e processor. It is a 64-bit RISC processor with 2x32kbyte cache. It features high speed processing and fast memory accesses. The F9601-11-16 processor is set to an internal clock of 96MHz and is used in a 32- bit mode.

Page 27: Dram
DRAM The DRAM consists of two SIMM modules from 4 MB up to 32 MB each. By interleaving two SIMMs, the access time is dramatically reduced (one beat every 30ns, while the other module “recovers” from the previous access). The DRAM control logic, including refresh control, is built around several GALs and a few gates.
Page 28: Memory Mapping
Memory Mapping By default, the board is set to the biggest memory size possible. The software checks out for “holes” in the addressing space, and sets accordingly two configuration lines, MAP1 and MAP0. MAP1..0 meaning 2x4, single sided SIMMs 2x8 MB SIMMs 2x32 MB SIMMs The VGA 65545 controller chip (A27) includes its own address decoding logic.
Page 29: Bus Sizer
Bus Sizer The MPC603e processor does not support dynamic bus sizing, as did the 68k family. Many parts of the software and the hardware rely on that feature. A Motorola MC68150 chip ‘translates’ the PowerPC 32-bit data bus to a 68030 8 or 16-bit bus. Except DRAM and VGA controller, all peripherals work on this 68k-type bus.
Page 30: Flash Prom
Flash PROM Two Intel 28F008-compatible 1MB PROMs (A24 and A25), are used. From a hardware point of view, a flash PROM is the same as an EPROM in read mode. To write to it, however, a programming voltage (Vpp) needs to be applied to a pin.
Page 31: Small Peripheral Interface
Small Peripheral Interface This 8-bit interface is intended to allow external expansion to the processor board. A56 and A53 (74HCT541 tri-state buffers) buffer the address and control lines, and A62 (74HCT245, bi-directional tri-state buffers) buffer the data lines. The address decoding is done on each peripheral board. The acknowledge for each access is also done by the peripheral device, so that there is no restriction on wait-states.
Page 32: Bus Error Generation
The power supply is monitored by a TL7770-5 chip. Whenever the Vcc voltage goes below 4.8V (even for a short time !), a reset pulse is generated, whose width is determined by an RC time constant (33uF and internal resistor). The second half of this chip serves as watchdog circuit.

Page 90: Bandwidth
Bandwidth 5.9.1 Description The purpose of this test is to ensure that the entire system has a bandwidth of at least 1.0 GHz. An external source is used as the reference to provide a signal where amplitude and frequency are well controlled. The amplitude of the generator as a function of frequency and power is calibrated using an HP8482A sensor on an HP437B power meter or equivalent.
