14 | NOTE: the SEC 4 is also known as Freescale's Cryptographic Accelerator | ||
15 | Accelerator and Assurance Module (CAAM). | ||
16 | |||
17 | ===================================================================== | ||
18 | Overview | ||
19 | |||
20 | DESCRIPTION | ||
21 | |||
22 | SEC 4 h/w can process requests from 2 types of sources. | ||
23 | 1. DPAA Queue Interface (HW interface between Queue Manager & SEC 4). | ||
24 | 2. Job Rings (HW interface between cores & SEC 4 registers). | ||
25 | |||
26 | High Speed Data Path Configuration: | ||
27 | |||
28 | HW interface between QM & SEC 4 and also BM & SEC 4, on DPAA-enabled parts | ||
29 | such as the P4080. The number of simultaneous dequeues the QI can make is | ||
30 | equal to the number of Descriptor Controller (DECO) engines in a particular | ||
31 | SEC version. E.g., the SEC 4.0 in the P4080 has 5 DECOs and can thus | ||
32 | dequeue from 5 subportals simultaneously. | ||
33 | |||
34 | Job Ring Data Path Configuration: | ||
35 | |||
36 | Each JR is located on a separate 4k page, they may (or may not) be made visible | ||
37 | in the memory partition devoted to a particular core. The P4080 has 4 JRs, so | ||
38 | up to 4 JRs can be configured; and all 4 JRs process requests in parallel. | ||
39 | |||

41 | SEC 4 Node | ||
42 | |||
43 | Description | ||

47 | configuration registers for the SEC 4 block. It | ||
48 | also receives interrupts from the Run Time Integrity Check | ||
49 | (RTIC) function within the SEC 4 block. | ||
