## Field Documentation

### uint16\_t k\_neg

The K- size of the input CB, in bits \[40:6144\], that is in the Turbo operation when r \< C-, as in 3GPP TS 36.212.

Definition at line **355** of file **rte\_bbdev\_op.h**.

### uint16\_t k\_pos

The K+ size of the input CB, in bits \[40:6144\], that is in the Turbo operation when r \>= C-, as in 3GPP TS 36.212.

Definition at line **359** of file **rte\_bbdev\_op.h**.

### uint8\_t c\_neg

The number of CBs that have K- size, \[0:63\]

Definition at line **361** of file **rte\_bbdev\_op.h**.

### uint8\_t c

The total number of CBs in the TB, \[1:RTE\_BBDEV\_TURBO\_MAX\_CODE\_BLOCKS\]

Definition at line **365** of file **rte\_bbdev\_op.h**.

### uint8\_t cab

The number of CBs that uses Ea before switching to Eb, \[0:63\]

Definition at line **367** of file **rte\_bbdev\_op.h**.

### uint32\_t ea

The E size of the CB rate matched output to use in the Turbo operation when r \< cab

Definition at line **371** of file **rte\_bbdev\_op.h**.

### uint32\_t eb

The E size of the CB rate matched output to use in the Turbo operation when r \>= cab

Definition at line **375** of file **rte\_bbdev\_op.h**.

### uint8\_t r

The index of the first CB in the inbound mbuf data, default is 0

Definition at line **377** of file **rte\_bbdev\_op.h**.
