CBGA Thermal Management Example
Assuming an air velocity of 1.0 m/sec, the associated overall thermal resistance and junction
temperature, found in Table 6 will result.
Vendors such as Aavid Engineering Inc., Thermalloy, and Wakefield Engineering can supply
heat sinks with a wide range of thermal performance.
Power Consideration
The PowerPC603r is a microprocessor specifically designed for low-power operation. As the
603e microprocessor version, the 603r provides both automatic and program-controllable
power reduction modes for progressive reduction of power consumption. This chapter
describes the hardware support provided by the 603r for power management.
Dynamic Power Management
Dynamic power management automatically powers up and down the individual execution units
of the 603r, based upon the contents of the instruction stream. For example, if no floating-point
instructions are being executed, the floating-point unit is automatically powered down. Power
is not actually removed from the execution unit; instead, each execution unit has an indepen-
dent clock input, which is automatically controlled on a clock-by-clock basis. Since CMOS
circuits consume negligible power when they are not switching, stopping the clock to an exe-
cution unit effectively eliminates its power consumption. The operation of DPM is completely
transparent to software or any external hardware. Dynamic power management is enabled by
setting bit 11 in HID0 on power-up, of following HRESET.
Programmable Power Modes
The 603r provides four programmable power states—full power, doze, nap and sleep. Soft-
ware selects these modes by setting one (and only one) of the three power saving mode bits.
Hardware can enable a power management state through external asynchronous interrupts
The hardware interrupt causes the transfer of program flow to interrupt handler code. The
appropriate mode is then set by the software. The 603r provides a separate interrupt and inter-
rupt vector for power management—the system management interrupt (SMI). The 603r also
contains a decrement timer which allows it to enter the nap or doze mode for a predetermined
amount of time and then return to full power operation through the decrementer interrupt (DI).
