Embedded Computational Unit (ECU)
Traditional Programmable Logic architectures do not implement arithmetic functions efficiently or effectively—
these functions require high logic cell usage while garnering only moderate performance results.
The QL58x0 device family architecture allows for functionality above and beyond that achievable using
programmable logic devices. By embedding a dynamically reconfigurable computational unit, the QL58x0
device family can address various arithmetic functions efficiently. This approach offers greater performance
and utilization than traditional programmable logic implementations. The embedded block is implemented at
the transistor level as shown in Figure 6.
Figure 6: ECU Block Diagram
The QL58x0 device family ECU blocks (Table 8) are placed next to the SRAM circuitry for efficient
memory/instruction fetch and addressing for DSP algorithmic implementations.
Up to twelve 8-bit MAC functions can be implemented per cycle for a total of 1 billion MACs/s when clocked
at 100 MHz. Additional multiply-accumulate functions can be implemented in the programmable logic.
The modes for the ECU block are dynamically re-programmable through the programmable logic.
