ocp 2.2 released

OCP-IP (Open core protocol international partnership) plans to release the new version of specifications OCP 2.2, directed toward to the improvement of performance system-on- chip (SoC). Into composition OCP-IP, created by the developer soC sonics, now enter more than 140 companies, among which vendor of solutions for the automation of design (EDA), the creators of intellectual property, designer and universities. OCP-IP as organization asserts that they allows the standard of universal interface socket, which can be applied to any micro-architecture or processor cores.

In OCP 2.2 will be the support to the flexible multifrequency synchronization also of the sequences of data bits, read from the two-dimensional blocks, the precise unblocked options of the data control, more flexible behavior with the restart, new profiles for security, necessary for the protection of information, and also new section with the control code for the verification.

In particular, in OCP 2.2 is added the signal enableClk, which makes possible for system to dynamically control effective clock frequency, without having the resorted phase self-alignment or to the additional chains of the distribution of clock signals with small distortions. The support of sequences data bits from the two-dimensional blocks in the batch mode is necessary for interaction with the graphic which work with the two-dimensional buffers of sequence, preserved in the external memory. In these sequences is coded all necessary information for obtaining entire two-dimensional packet with one demand, which makes possible to increase the performance of interface and to optimize access to the pages of operational memory.

The new unblocked data control is added for facilitating the development of completely synchronous designs. This makes possible to control the plural flows of data even with the considerable increase for clock frequency. Additionally, the section of specifications describes the verification of compatibility, configuration and functionality for interface OCP.

The work on OCP 2.2 was excuted within the OCP-IP specification working group, into which entered the representatives OF MIPS technologies, Nokia, Sonics, Texas instruments and Toshiba.
