6MACH 4 Family
Table 4. Architectural Summary of MACH 4 devices
The Macrocell-I/O cell ratio is dened as the number of macrocells versus the number of I/O
cells internally in a PAL block (Table 4).
The central switch matrix takes all dedicated inputs and signals from the input switch matrices
and routes them as needed to the PAL blocks. Feedback signals that return to the same PAL block
still must go through the central switch matrix. This mechanism ensures that PAL blocks in MACH
4 devices communicate with each other with consistent, predictable delays.
The central switch matrix makes a MACH 4 device more advanced than simply several PAL
devices on a single chip. It allows the designer to think of the device not as a collection of
blocks, but as a single programmable device; the software partitions the design into PAL blocks
through the central switch matrix so that the designer does not have to be concerned with the
internal architecture of the device.
Each PAL block consists of:
◆ Product-term array
◆ Logic allocator
◆ Macrocells
◆ Output switch matrix
◆ I/O cells
◆ Input switch matrix
◆ Clock generator
