Patent ID: 7356671

Claim:
An integrated circuit for voice and video over data network applications, the circuit comprising: a first and a second processors; a plurality of coprocessors coupled to the processors, the plurality of coprocessors includes, at least first and second digital signal processing coprocessors (DSP-COP), a VCODEC engine, a security engine, a network processor (NP) and a video scaling controller (VSC), wherein the first and second DSP-COP perform signal processing and audio codec, the VCODEC engine compresses and decompresses video frames, the security engine encrypts and decrypts data packets, the NP parses data packets to accelerate routing of the data packets and the VSC scales up and down size of video frames; a shared memory coupled to the processors and the coprocessors; a memory controller coupled to the processors for accessing data stored on an off-chip memory; and a transaction management engine (TME) coupling to the shared memory and to the memory controller, wherein the TME manages at least one transaction in accordance with at least one task queue, respectively.
