Have you ever used an embedded processor on an FPGA?

- G. n. R1 ?( Q% y4 k: hBoth processors are very similar to program. PowerPC offers substantial increase in performance, lower logic consumption, DCR and PLB bus. DCR bus is very handy while I think that PLB bus can replaced by OPB to simplify designs. There is a major drawback of hard processors - any errata cannot be corrected with updates (like PPC cache errata).

隨著消費性科技產品日新月異，功能日趨複雜，降低功耗、縮短產品上市時程、以及降低成本已達到量產效益已成為設計業者最關心的議題。可編程(programmability)技術自問世以來便成為系統設計業者到達成功彼岸的最佳利器？全球可編程邏輯解決方案領導廠商為滿足此市場需求，紛紛以全新低成本、高量產型FPGA元件產品為系統設計業者帶來更多功能與經濟效益，創造出符合市場需求的消費性電子產品。同時，各廠商更為設計業者在可編程邏輯、連結功能、和專屬的硬式IP與成本之間提供一個獨特的最佳平衡點？
