RAM Power Consumption
In XC4062XL devices, each CLB can be used as a 32
×
1 RAM structure, and larger RAM blocks are built
by combining multiple CLBs. In EPF10K100A devices, RAM is implemented in EABs, which contain
2,048 bits of RAM that can be configured in several configurations with widths up to 8 bits wide. On
average, RAM implemented in FLEX 10KA EABs used 90% less current than RAM implemented in
XC4000XL CLBs (see
Figure 3
).
Figure 3. RAM Power Consumption
Clock Tree Power Consumption
The EPF10K100A device consumed less power than the XC4062XL device for several reasons. For
instance, the XC4062XL device had a large clock tree that consumed more power than the EPF10K100A
clock tree (see
Figure 4
). A global clock tree is a network of buffers and signal lines that are connected to
all of the registers in the device to ensure that all destinations receive signal transitions simultaneously. In
the experiments, the EPF10K100A clock tree consumed 42% less power than the XC4062XL clock tree.
Figure 4. Clock Tree Power Consumption
The clock tree power consumption is directly affected by the size of a clock tree, which, in turn, is directly
related to the device’s die size. The die of the XC4062XL device is 1.9 times larger than that of the
EPF10K100A device (see
Figure 5
). Therefore, the XC4062XL clock tree consumes more power than the
EPF10K100A clock tree.
