The invention provides a packet processing apparatus and an associated packet processing method. The packet processing apparatus includes a buffer manager (BM) circuit, an ingress drop queue manager (IDQM) circuit, and a queue manager (QM) circuit. When the ingress packet is decided to be dropped for at least one egress port designated by the ingress packet, the QM circuit enqueues the ingress packet into the IDQM circuit without enqueuing the ingress packet into at least one egress queue of the at least one egress port, and the IDQM circuit refers to the ingress packet enqueued therein to request the BM circuit to perform cell release of the ingress packet. The packet processing apparatus and the associated packet processing method may quickly release used cells of a received packet in the multicast counter memory. 本发明提供种分组处理装置及相关的分组处理方法。分组处理装置包含有缓冲管理器电路，入口丢弃队列管理器电路，以及队列管理器电路，其中对于由输入分组所指定的至少输出端口而言，当输入分组被决定丢弃时，队列管理器电路用来将输入分组入队于入口丢弃队列管理器电路之中而无需将输入分组入队于至少输出端口的至少输出队列，以及入口丢弃队列管理器电路用来参照入队于其中的输入分组，来请求缓冲管理器电路来进行输入分组
