Math with a twist

摘要

Regardless of whether you can use Quick-Logic's QuickDSP chips, you have to give the company credit for creative interpretation of the term "digital-signal processing." QuickDSP is the second of QuickLogic's embedded-standard-product family; the first, QuickPCI, combines a range of ASIC-based PCI cores with RAM blocks and antifuse-based user-programmable logic. This time around, the company devotes the ASIC gates to arithmetic circuits, which it calls embedded computational units (ECUs). Each ECU can implement several single-pass asynchronous and registered functions (8 X 8-bit multiply, 16-bit add, or accumulate with carry) with multiple passes through the ECU sup- porting the common multiply/accumulate function.
